This plan is designed, specifically, for success at the Austin Rattler 100k Marathon MTB Race. The plan progresses from building aerobic foundation, increasing intensity and load, culminating with a final taper to race day. This plan works best for the intermediate rider with 10-13 hours per week to dedicate towards training. Training is designed with the working man and/or woman in mind, with rides of 90min or less Monday-Friday, and longer on the weekends. A power meter will make this plan the most beneficial, but both heart rate and power meter zones are outlined. In week two, the athlete will do a field test to establish power and/or heart rate zones.
