Three weeks hard followed by a recovery week provide physical and mental adaptation to training stresses for a 100-mile race. We use training cycles of three weeks hard, one week easy to allow for recovery and help prevent overuse injuries or burnout.

The exception is that the 100-mile running plan will reach higher total weekly mileage (70 miles per week) than our other ultramarathon running plans. This running plan is very similar to our 50-Mile and 100k Training Plans.

Have you signed up to run your first 100-mile ultramarathon? Have you completed a few 100-mile races before and now are looking to follow a structured training plan on your way to the next finish line? The 100-miler is one of the most challenging events in all sports, and some of the most popular ultras in the world are set at this distance, such as the Western States 100 Mile Endurance Run, Hardrock 100, and Leadville 100! If you’ve completed a few 50k or 50-mile races, then you should be adequately prepared for our 100 Mile Ultramarathon Training Plan. Running Club and Running Stickers for the Endurance Enthusiasts
