My Pro Coach training plans range from 8 to 40 weeks in duration (available in 4-week increments). When deciding on the length of your plan, you should count back from your "A" target race date and then choose a plan to fill that gap. You can calculate the number of weeks between two dates by using this online time duration calculator.
The longer the plan you choose, the better. As this will give you more chance to gradually build up your training and fitness. The body responds well to constant progression with regular recovery periods, and that's exactly what our training plans will give you.
The training plans will take you right up to race day (aside from the Winter base plans). The longer the plan the easier it starts and the more gradually it progresses. For example a 16 week plan starts off at a higher level than a 32 week plan, because there's not as much time left before race day.
