Factors Affecting Half-Marathon Times

Many factors can affect half marathon times. Age, gender, fitness level, weather, and course terrain are all significant factors. As runners age, they typically lose muscle mass, leading to slower times. Male runners usually outperform female runners in terms of speed. Fitter runners can run faster than less fit runners. After age 40, most runners’ times start to slow down. Most half-marathons use age grading to compare times to provide fair and equal opportunities. Weather and course terrain can affect half-marathon times significantly. Running on a flat rather than a hilly one will generally result in a faster time. It can be tough to race in the cold if you live and train in the heat.
