100 Mile MTB Training Specific Build Plan - 12 weeks

Plan Description

This plan is for Intermediate and advanced riders doing a 100 mile mountain bike race
It is designed to be start after a base plan where you accumulate a general base of fitness
*I have an offroad base plan that is a great option*

This plan will get you fit but also make sure you are prepared technically, tactically, and logistically. It follows the same progressions and ideas I have used to help athletes through big races like Leadville, Marji Gesick, Lumberjack and more.

Because 100 mile mountain bike races can range in technicality and physiological demands there are a few notes on how to adjust key preparation workouts to better prepare you for your specific 100 miler.

The plan requires about 6-8 hours in shorter weeks up to 12-15 hours in longer weeks. The workouts suggest a range that you choose based on your daily availability and your baseline fitness.

Weekly/monthly notes are included to help you prepare to succeed.

This plan has structured downloadable workouts (e.g. for Zwift/Garmin) but as the race approaches there are fewer as you are expected to be outside exploring and working on your pacing so a download file is redundant if not distracting from the goal of your workouts.
If you have an irregular schedule, want to race a lot, or if this race is a very big stretch for you then you will want to consider a 3- month 100% made for you plan
For $99, I offer 3 months 100% Made For You Plans, which often works better as it takes your schedule, goals, equipment, and abilities into account =
