This plan is designed for the busy athlete and can easily fit into your life. Weekday workouts are mostly kept to under 90 minutes. The concept is to build your power and speed during the week, then maximize the weekend hours to build your endurance. There are optional workouts and workouts you can move depending on your schedule. The goal is not only to increase your fitness, but to have you enjoy the journey.

It follows a 3 week build/ 3 day recovery cycle, which allows you to get in more aerobic training over the weekends. Tests in each sport at the start of the plan set your zones perfectly, and another set of tests at the end show your improvement and allow you to create the perfect race strategy.

More than just workouts, there are also tips on nutrition, terminology, pacing and race strategy as well as notes to keep you on track for success.

It features a 2 week taper and tips on building your perfect race plan.
With this plan, you'll be ready to be your best on race day.
