To start this plan you should already be capable of swimming 1 hour, biking 90 minutes and running 1 hour. The emphasis in the first 8 weeks of this plan is on running. In the last 4 weeks the emphasis shifts toward the bike. Each week there are 3 swims, 2-5 rides, 4-5 runs and 1-2 strength workouts. Weekly volume increases from 12 to 17 hours. The exception is in R&R weeks every fourth week when training is greatly reduced for 4-5 days culminating with self-testing. These R&R weeks will allow for adaptation and improved performance.
