This plan is the next plan in the set, so make sure you do the weeks 1-8 first before embarking on this adventure. Designed to solidify all the fitness you gained in the first 8 weeks, weeks 9-16 will continue to challenge you and push you to the next level. It's best used by someone with 10-14 hours a week to train and is a sport rider and ready to push to the next level. Hunter and I designed it to bring out the best in you each day and challenge you to become great. If you have a heart rate monitor or power meter, then this plan will be easy to follow and give you specific instructions each day. Get ready for yet another step up on the podium!
