“The woods are lovely, dark, and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.” Robert Frost
On March 30, 2026, NEPA lost one of its most dedicated conservationists, Dorrance Reynolds Belin…our version of John Muir, Theodore Roosevelt, and Rachel Carson. While Dorrance served on numerous boards, in my view, he will be most fondly remembered for his environmental stewardship as founder of the Eastern Pennsylvania Chapter of the Nature Conservancy and Countryside Conservancy. I am not sure if Dorrance ever had the pleasure of meeting Robert Frost, Pulitzer Prize winning American Poet, but it is not hard to imagine that he had Dorrance in mind when writing the above poem. Thank you Dorrance, and those who worked with you, for the vision and foresight to preserve these special places for our children, grandchildren and great grandchildren to enjoy!
According to their mission statement, The Countryside Conservancy manages 1,190 acres of lands and waters to protect their conservations value. Most of these acres are open to the public for visitation and many have trails. Collectively, the conservancy contributes to 10 miles of singletrack hiking and biking trials to the 30-mile Lackawanna State Park/Countryside Conservancy Trail System …for more information visit: countrysideconservancy.org.
Please get outdoors and enjoy the trails…walking, running, biking, snowshoeing, cross-country skiing or horse back riding. But if you want to try something new this spring that will allow you to exercise on more interesting and less stressful surfaces in the beautiful woods of Northeast Pennsylvania…try trail running!
Trail running forces one to run 25% slower due to the uneven terrain (rocks, tree roots, stumps), incorporate “light running” techniques by running with short strides on the balls of my feet. You will feel much more refreshed by avoiding the direct sunlight under the cover of the trees. Furthermore, you can enjoy the up-close view of nature as I ran by cool streams and wet mossy rocks, beautiful flowers, rhododendron, and mountain laurel. Observe deer, chipmunks and birds. In my quest to avoid the hot sun, I discovered the beautiful underworld of “trail running” - it is beautiful, peaceful, natural and unique. It is fun to get in touch with your inner child as you run in the woods and get muddy. Trail running makes running fun…and it’s good for your joints!
The trail running community purports that trail running is popular because it satisfies a primal need for man to move through nature, derived from hunter/gatherer days. Others who promote trail running feel the popularity is due to the many advantages it offers. One, trail running prevents impact injuries due to soft surfaces. Two, the training style of running with shorter strides on the ball of the foot, lessens impact. Three, this type of running will develop stronger ankles and trunk core muscles while improving balance, coordination and proprioception from running on uneven surfaces. Lastly, the ability to release copious amounts of endorphins while breathing fresh air instead of roadside fumes is invaluable.
Find a Trail – Start by asking around. Hikers, mountain bikers, and horseback riders are a good start. The American Trail Running Association has a website with a free directory of trails in the United States. PA State Parks such as Lackawanna State Park in Dalton, offer many options www.visitPAparks.com, countrysideconservancy.org. or download the app AllTrails. Learn the difference between “nontechnical trails” which are wider with a paved, dirt or gravel base and much easier than “technical trails” which are narrow, rocky, hilly and challenging.

Spring has sprung in NEPA and summer is just around the corner... great news for outdoor enthusiasts! It is also good news for those who need walk for health reasons. However, for many who have not maintained an active lifestyle or have health issues, it is challenging to know where to begin. Moreover, beginning without a good plan can lead to injury and leave you discouraged. For example, those overweight and de-conditioned should not start a walking program too aggressively. Walking at a fast pace and long distance without gradually weaning into it will most likely lead to problems.
There is probably nothing more natural to human beings than walking. Ever since Australopithecus, an early hominin (human ancestor) who evolved in Southern and Eastern Africa between 4 and 2 million years ago, that our ancestors took their first steps as committed bipeds. With free hands, humans advanced in hunting, gathering, making tools etc. while modern man uses walking as, not only a form of locomotion, but also as a form of exercise and fitness. It is natural, easy and free...no equipment or fitness club membership required!
“There’s no question that increasing exercise, even moderately, reduces the risks of many diseases, including coronary heart disease, breast and colon cancer, and Type 2 diabetes,” said Dr. Jennifer Joyce, MD, professor of family medicine at GCSOM. “Research has even shown that you could gain two hours of life for each hour that you exercise regularly.” A recent study demonstrated that a 15 minute walk after a meal is very effective in reducing blood sugar levels.
According to the American Heart Association, walking as little as 30 minutes a day can provide the following benefits:
Anything is better than nothing! However, for most healthy adults, the Department of Health and Human Services recommends at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity, or an equivalent combination of moderate and vigorous aerobic activity. The guidelines suggest that you spread out this exercise during the course of a week. Also aim to do strength training exercises of all major muscle groups at least two times a week.
As a general goal, aim for at least 30 minutes of physical activity a day. If you can't set aside that much time, try several short sessions of activity throughout the day (3 ten or 2 fifteen minute sessions). Even small amounts of physical activity are helpful, and accumulated activity throughout the day adds up to provide health benefit.
Remember it's OK to start slowly — especially if you haven't been exercising regularly. You might start with five minutes a day the first week, and then increase your time by five minutes each week until you reach at least 30 minutes.
For even more health benefits, aim for at least 60 minutes of physical activity most days of the week. Once you are ready for a challenge, add hills, increase speed and distance.
Keeping a record of how many steps you take, the distance you walk and how long it takes can help you see where you started from and serve as a source of inspiration. Record these numbers in a walking journal or log them in a spreadsheet or a physical activity app. Another option is to use an electronic device such as a smart watch, pedometer or fitness tracker to calculate steps and distance.
Make walking part of your daily routine. Pick a time that works best for you. Some prefer early morning, others lunchtime or after work. Enter it in your smart phone with a reminder and get to it!
Studies show that compliance with an exercise program is significantly improved when an exercise buddy is part of the equation. It is hard to let someone down or break plans when you commit to someone. Keep in mind that your exercise buddy can also include your dog!

Like everything, there is a right way of doing something, even walking. For efficiency and safety, walking with proper stride is important. A fitness stride requires good posture and purposeful movements. Ideally, here's how you'll look when you're walking:

Spring sports and outdoor activities are here…tennis, pickleball, baseball, soccer, running, walking, hiking, golfing, etc. One of the most common injuries associated with physical activity, especially after a sedentary winter or change in temperature is a “pulled hamstring.” This painful injury is not only for the weekend warrior. Well-trained, healthy and fit professional athletes often have their season interrupted for weeks and months due to a hamstring injury. What is the hamstring? How is it injured? What is the best treatment?
A hamstring strain is a tear of the muscle fibers of the muscle group in the back of the thigh called the hamstring. The hamstring muscle is a group of three muscles that run from the back of the hip (lower pelvis), crossing the back of the knee and attaches to the knee bone (tibia). The hamstring muscles work to extend the hip and bend the knee during running and walking activities. They are very active when an athlete changes direction, especially forwards and backwards or decelerating. This injury, like others muscle strains, varies in intensity.
Severe hamstring strain occurs when many muscle fibers are torn. The athlete may experience a sudden onset of severe pain in the back of the thigh and occasionally report a popping sensation. Pain, swelling and black and blue skin from tissue damage and bleeding is often reported. Also, pain is reproduced when attempting to bend the knee. In very severe cases, the boney attachment can be pulled so strongly that a small fracture can occur. Healing time can be as short as a few days or as long as weeks or even months.
Your family physician will examine the back of your leg to determine if you have hamstring strain. Sometimes, pain in the buttocks and back of the leg can be referred from your lower back if the sciatic nerve is inflamed. In more advanced cases, you may be referred to an orthopedic surgeon for further examination and treatment. An X-ray, MRI or bone scan will show the extent of the tear and if the bone is involved. The diagnosis will determine if your problem is minor, moderate or severe.
There are many conservative options. Your family physician or orthopedic surgeon will help you decide which choices are best.
Recent studies have determined that a training program specifically designed to prevent hamstring injuries is effective, especially for the competitive athlete. This program includes:

Patients often tell me that they would like to exercise but hesitate due to their knee or hip pain. They want to know what they should avoid, how to prevent and what is recommended to prevent or limit the progression of arthritis. Osteoarthritis (OA) is also known as degenerative arthritis. It is the most common form of arthritis in the knee. OA is usually a gradual, slow and progressive process of “wear and tear” to the cartilage in the joint which eventually wears down to the bony joint surface.
It is most often found in middle-aged and older people and in weight bearing joints such as the hip, knee and ankle. It causes gradual onset of pain, swelling and stiffness in the joint involved, especially after increased activity. While diet and exercise help, some people are more likely to develop OA based on previous trauma or injury, labor intensive occupations and genetics. Either way, we all get OA to some degree but there are a few things you can do to limit wear and tear to your joints.
However, OA is not an excuse to avoid exercise, but it is important to be smart about it. Regular exercise is essential to maintain a normal lifestyle for those with OA. However, if you make poor lifestyle choices, do the wrong exercise, use poor technique, or are too aggressive, you could flare-up your joints and do more harm than good.

It is one week away from the 28th Steamtown Marathon. This column is dedicated to all the runners preparing for the big day. One small piece of advice; start slowly, avoid the first mile adrenaline sprint downhill, and enjoy the journey! Remember, only one Olympic marathon winner (Juan Zabala, Argentina, 1932) was in the lead at the 5 mile mark. Lesson: The last miles matter more than the first!
Today, I hope to address some common questions for the novice marathon runner or for those coming from other locations to run in the race. What should you pack? How should I dress? What supplies will I need?
Elite runners are so experienced that they know exactly what to pack in preparation for the big day. However, those, running in marathon for the first or second time usually have lots of questions. First, what you need and what you can bring will depend on your support team. If you are running alone and will not have family or friends meeting you along the way, then you are limited to a fanny pack and a few supplies. If you have a support team, then they can carry a bag with supplies, meet you along the course and you can have a sense of security.
Remember; do not do anything different on race day. Try out special clothing, water with supplements and snacks on a practice run. Also, experiment with your best pre-race meal. You will be getting up at 5-6:00am to catch the bus from Scranton to Forest City. You may want to pack breakfast to eat in the high school gym such as; bagel, peanut butter, jelly, banana and coffee or Gatorade. Moving your bowels before the race is a must.
Columbus Day Weekend in NEPA could bring 30 to 40 degree temperatures when you catch the bus in Scranton and at the 8:00 am race starting time in Forest City.
If you don’t mind the little pack on your butt, a fanny pack can be valuable. In it, you will want supplies such as: small bandages, small roll of medical tape, ibuprofen, antacid tablets, small tube of lubricant, favorite running snack, and extra shoe laces. One might also consider packing a little money, credit card, ID, emergency contact numbers and medical insurance cards. A cell phone is optional.
Have your support team meet you at prearrange locations along the race route and bring your supply bag. In the bag, you might consider all of the above fanny pack items and: A change of clothes such as: extra running shoes, socks, shorts, shirt, water proof wind breaker, according to the weather, especially if rain is predicted. Towels, ace bandages, gauze pads and wrap, antibiotic cream, mole skin, sunscreen, petroleum jelly, safety pins, extra water and favorite sport drink, favorite sport snacks, extra ibuprofen, antacid, anti diarrhea medicine, chemical ice pack, mobile phone, money, credit cards, ID, medical insurance cards.
For those with allergic reactions, remember to pack: epinephrine, antihistamine, and other important medications.

It is two weeks away from the 28th Steamtown Marathon. After training all spring and summer for the first seven Steamtown Marathons, not a Columbus Day Weekend goes by without my thoughts of this great event.
I would like to introduce this topic with some marathon history. In 490 B.C. Athens was under attack by the Persians and was outnumbered more than two to one. The Athenians fought bravely and defeated the enemy in the town of Marathon. The victory kept the intruders 26 miles away from Athens. To keep the anxious citizens of Athens calm, leaders immediately ordered a foot soldier, Phedippides, to run to the capital city to share the news. Phedippides ran, in full armor, for 26 miles from Marathon to Athens, delivered the message and died immediately. Now, people do the same thing of their own free will!
Each year at this time, dozens of runners preparing for the Steamtown Marathon come to my office with severe shin pain known as shin splints. Unfortunately, in many of these athletes, this problem can lead to a much more severe and advanced problem with shin splints called a stress fracture.
A stress fracture is fatigue damage to bone with partial or complete disruption of the cortex of the bone from repetitive loading. While standard x-rays may not reveal the problem, a bone scan, and MRI will. It usually occurs in the long bones of the leg, mostly the tibia but also the femur (thigh) and foot. Occasionally, it occurs in the arm.
10-21% of all competitive athletes are at risk for stress fractures. Track, cross country and military recruits are at greatest risk. Females are twice as likely as males to have a stress fracture. Other athletes at risk are: sprinters, soccer and basketball players, jumpers, ballet dancers are at risk in the leg and foot. Gymnasts are also vulnerable in the spine while rowers, baseball pitchers, golfers and tennis players can experience the fracture with much less frequency in the ribs & arm.
The problem is much more prevalent in weight bearing repetitive, loading sports in which leanness is emphasized (ballet, cheerleading) or provides an advantage (distance running, gymnastics).
Stress fractures usually begin with a manageable, poorly localized pain with or immediately after activity such as a shin splint. Over time, pain becomes more localized and tender during activity and then progresses to pain with daily activity and at rest.
Visit your doctor regularly and listen to your body.

Happy Labor Day! There is little doubt that the workplace has been redefined since the pandemic as many employees continue to work from home. Sitting for many hours at a workstation that may not be optimal has also changed the way we define workplace health and safety. It may be more important than ever to pay close attention to designing an ergonomic workstation, changing position, and stretching regularly to prevent injury.
Since 1894 Labor Day has been designated as the national holiday that pays tribute to the contributions and achievements of American workers. Research supports the notion that healthier employees are happier and more productive. When employers encourage healthy behavior and safety at work, they benefit in many ways.
For example, in addition to improving job satisfaction and productivity, healthy employees save money by using less sick time, worker’s compensation benefits and health benefits. For example, according to the Centers for Disease Control and Prevention, approximately 75 percent of employers” health care costs are related to chronic medical problems such as obesity, diabetes, high blood pressure, and high cholesterol. Deconditioned, overweight employees are more likely to suffer from these preventable conditions and are at greater risk for injury. Employers, please consider using this holiday as an opportunity to start a health promotion program at your workplace…have a health fair, offer healthy snacks, encourage walking, smoking cessation, exercising at lunch, and offer fitness club stipends.
Lower back pain, one of the costliest illnesses to employers, is one example of a problem which can be prevented with a good health and safety program. It is widely accepted in the medical community that the best treatment for lower back pain (LBP) is prevention. Keeping fit, (flexible and strong), practicing good posture, and using proper body mechanics are essential in the prevention of LBP. At our clinic, significant time and effort is spent emphasizing the importance of these concepts to our patients, employees, and the businesses we work with through industrial medicine programs. A comprehensive approach can produce significant reductions in LBP injuries through an onsite safety program which promotes education, wellness, body mechanics, lifting techniques, postural and stretching exercises and ergonomics.
As little as 10 extra pounds puts great stress on your lower back. It also makes it more difficult to maintain good posture. Eat well, exercise regularly and don’t smoke. Smokers have a much higher incidence of LBP and failure from lower back surgery.
Good posture is critical for a healthy back. When sitting, standing or walking maintain a slight arch in your lower back, keep shoulders back, and head over your shoulders. In sitting, use a towel roll or small pillow in the small of the back. Also, consider sitting on a physio ball, which promotes proper posture for part of the day.
Perform postural exercises throughout the day. Most of the day we sit, stand, and reaching forward and bend our spine. These exercises are designed to stretch your back in the opposite direction of flexion. Please perform slowly, hold for 3-5 seconds and repeat 6 times each 6 times per day.
Chin Tuck: Tuck your chin back to bring your head over shoulders.
Shoulder Blade Pinch: Pinch your shoulder blades together.
Standing Extension: While standing, put your hands behind back and extend lower back 10-20 degrees.
Good Body Mechanics and ergonomics are also important in the prevention of LBP. When lifting, think twice. Think about the weight, shape and size of the object. Think about where the object is going and the surface resistance of the floor. Does it require two people to lift? Can I safely lift that high or bend that low?
When bending to lift an object think about safety:

This column is repeated every year at this time with the intent of raising the level of awareness to prevent death or serious illness from heat stroke in athletes and other active people in hot, humid weather.
It is early August, and we have managed to survive two “heat waves” in NEPA. While it is important to have fun in the sun, please be mindful of how your body reacts to high humidity and heat and take appropriate precautions. Athletes are particularly vulnerable this time of year due to daytime practice sessions. In response to this potential problem, the PIAA has established acclimatization guidelines for fall sports beginning in August. Visit www.piaa.org for more information. Keep in mind, you don’t have to be running a marathon or playing football in full uniform to suffer from heat stroke.
Heat stroke, one of the most serious heat-related illnesses, is the result of long term exposure to the sun to the point which a person cannot sweat enough to lower the body temperature. The elderly and infants are most susceptible and it can be fatal if not managed properly and immediately. Believe it or not, the exact cause of heatstroke is unclear. Prevention is the best treatment because it can strike suddenly and without warning. It can also occur in non athletes at outdoor concerts, outdoor carnivals, or backyard activities.
Some “old school” folks think that wearing extra clothing and “breaking a good sweat” is an optimal goal for exercise. However, it may be potentially very dangerous in hot and humid conditions. When exercising in hot weather, the body is under additional stress. As the activity and the hot air increases your core temperature your body will to deliver more blood to your skin to cool it down. In doing so, your heart rate is increased and less blood is available for your muscles, which leads to cramping and other more serious problems. In humid conditions, problems are magnified as sweat cannot be evaporated from the skin to assist in cooling the body.
The American Academy of Pediatrics and The American College of Sports Medicine has the following recommendations which are appropriate for both the competitive athlete and weekend warrior:
