Hal Higdon: Triathlon 2 Training Program: This Triathlon 2 Training Program is designed for runners who would like to test their fitness in a triathlon by adding swimming and cycling to their workout routines. It assumes a moderately high level of fitness, certainly an ability to finish 5-K or 10-K races if not marathons. It can prepare you to participate in sprint triathlons, those shorter than the Olympic distances: 1500 swim, 40-K bike, 10-K run. Each day I will send you an email telling you how to work out and offering training advice. For more information, visit my website: halhigdon.com.
