About the Half Marathon
The half marathon (13.1 miles) is often considered the perfect distance: long enough to be a challenge, but without the intensive preparation of a full marathon. It's one of the most popular road races worldwide.
The key to a successful half marathon is pace management. Start slightly below your target pace for the first 5 kilometers, settle into rhythm, then gradually accelerate in the final 5 kilometers if you feel strong.
