This 14 week half marathon plan incorporates swimming, biking and weights as cross training and is perfect for an athlete training for a half marathon prior to beginning half distance triathlon training.

Weekly training totals are 8 to 11.5 hrs per week with 3 runs, 2 swims, 2 bikes, and 2 strength sessions. The plan begins with a weekly total of 1:30 running, 2:45 biking, 1:05 swimming.

Fridays are days off for maximum flexibility (if something comes up during the week, that becomes your off day and you make up training on Friday). The training cycle is 2 weeks of build followed by 1 week of recovery.
