If you’ve got the guts for a triathlon — but not enough hours to train — try a shorter version. A sprint triathlon is a half-mile swim, 12-mile bike ride, and 3-mile run. This is half the distance of an Olympic triathlon and less than a quarter of the distance of the Ironman. Distances may vary slightly from event to event, but they typically adhere to the above standards. Because of their shorter distances, sprint triathlons have become increasingly popular and are ideal for beginner or novice athletes.
A checkup is a must before any new workout if you’re 45 or older or you have health issues.
