Smart Tips for Running Marathons

The journey from the starting line to the finish line of any race is smoother when you train smart and care for your body. “Preparing for a running race requires planning, discipline, and the right support, no matter if it’s a 5k, half-marathon, or full marathon,” says PIH Health Physician David Lewis MD.

Start with a training plan. Each race distance demands a different level of preparation. A 5k may take six to eight weeks of training, a half-marathon around three to four months, and a marathon up to six months. A structured training plan should gradually build mileage and balance running with rest and cross-training.

Invest in the right shoes. “Running long distances on the wrong shoes can cause injuries like shin splints, knee pain, or blisters,” says Dr. Lewis. The best shoes for you depend on your gait and foot type. Specialty running stores are recommended to analyze your stride and help find the right shoe. Most pairs last about 300–500 miles, so make sure to replace them before they lose their support.

Prioritize warm-ups and cool-downs. A proper warm-up should include a short, brisk walk or light jogging followed by dynamic stretches like high knees or lunges. After a run, slow to a walk and then stretch your calves, hamstrings, and quads. This routine can help prevent common running injuries and speed recovery.

Fuel and hydrate properly. Race-day success begins long before the starting line. For a 5k, a small snack like a banana or oatmeal may be enough. Half-marathoners and marathoners, however, need to practice “fueling” during long runs. Energy gels, chews, or sports drinks provide carbohydrates that keep your body fueled mile after mile. Drink water throughout the day and add electrolytes on longer training runs or in hot weather.

Prepare for race day. Sticking to your routine on race day is key to performing at your best. Avoid introducing anything new including shoes, clothing, nutrition, or gear. Small changes can throw off your rhythm or cause discomfort. Your routine is designed to work with the habits your body and mind are familiar with.
