This training plan is designed for first-time half Ironman participants who want to do just enough training for a successful finish. The plan is 20 weeks long. It begins with an 8-week base phase, followed by a 6-week build phase and a 6-week peak phase. Odd-numbered training weeks include 3 swims, 3 rides, and 3 runs. Weeks 2, 6 and so forth include 3 swims, 2 rides, 3 runs, and a bike-run brick workout. Weeks 4, 8 and so forth include 3 swims, 3 rides, 2 runs, and a bike-run brick. Every fourth week is a recovery week. Optional tune-up triathlons are scheduled in Week 12 (sprint) and Week 16 (Olympic distance). The final 10 days of each plan constitute a tapering period. The plan begins with 3,900 yards of swimming, 2 hours and 45 minutes of cycling, and 1 hour and 45 minutes of running in Week 1. It peaks with 6,700 yards of swimming, 5 hours and 20 minutes of cycling, and 3 hours and 7 minutes of running in Week 17.
