The Pros Behind The Plans

The creators of our training programs have raced (and won!) the most competitive mountain and trail ultras, and they understand the unique demands of 50K to 100-milers: vert, fueling, recovery, and the long grind.

TRACER vs Traditional Training Plans

TRACER programs react to each user individually.

TRACER programs adjust to your schedule, your feelings, and your activities, on a daily basis.

TRACER takes your feedback and adjusts your plan going forward.

TRACER adaptations mean you build fitness more effectively, and are less likely to overtrain, burn out, or get injured.

Off-the-shelf static plans are made for a mass audience.

Static plans are inflexible, you have to work around them.

You can't give feedback to a traditional plan.

Static plans assign you workouts regardless of how you feel, increasing the risk of overtraining and injury.

Our Users Get Real Results

"I really couldn’t have asked for a better season. I had major PRs at several races and finished 3rd in the Elite division at the Spartan Killington Beast, ~14 miles with nearly 7,000 feet of climbing at 40% grades. Even more impressive has been how durable I feel. I’ve recovered much faster from races this year, and getting through a heavy mountain season at 40 without injury feels like an accomplishment of its own. I want to keep doing this for a very long time!"
