About Ultrarunning.AI
The complete platform for ultrarunners and everyone who shows up for them.
Ultrarunning.AI is the definitive ecosystem for athletes pushing past the marathon, built to help you train smarter, race farther, and coordinate the people who get you to the finish line. We combine adaptive coaching, race logistics planning, nutrition strategy, and performance analytics into a single free platform designed around the realities of ultramarathon preparation. From your first 50K to multi-day 200-mile efforts, the platform adapts to your goals, your terrain, and the way you actually run.
The platform is for ultrarunners of every level, first-timers working toward a debut, experienced athletes chasing personal bests, and frontier-distance runners tackling 200-mile and multi-day events. It's also for the people behind every finisher: crew chiefs coordinating aid-station handoffs, pacers jumping in for the dark miles, and coaches managing rosters of athletes. Crew Central brings race-day logistics, aid-station timing, pacer schedules, and shared trip planning into one place so no detail falls through the cracks on race weekend.
That's the platform. Below is why it exists, one founder's answer to a problem he lived through himself, long before it became a product.

Why I Built Ultrarunning.AI
Every ultra training plan I could find was the same: static, generic, built for a version of my life that doesn't actually exist. A twelve-week plan doesn't know that work got insane this month, that your knee's been off since Tuesday, or that you skipped last week's long run because life got in the way, again. It just sits there, unchanged, waiting for you to fail to keep up with it.
I wanted something that actually adapts. Not a plan you follow, but a coach that pays attention, to your fitness, your recovery, your schedule, your goals, and the hundred small things that shift every single week of training for something this hard.
But the bigger problem was never really the plan. It's the miles in between.
Ultra training is lonely in a way that's hard to explain to anyone who hasn't done it. Months of early mornings, alone, working toward something almost nobody in your life fully understands. And race day doesn't solve that, it just changes the shape of it. Now you need a crew. Pacers. Someone at mile 60 who knows exactly what you need before you can find the words to ask for it.
It takes a village to get someone to a hundred-mile finish line. Even if that village is a population of one (you), you can still use the organization, the planning, and the sense that someone's got your back when things go sideways at 2am on a mountain.
That's what I built. Ultrarunning.ai adapts to your actual life instead of an imaginary one, and Crew Central helps you build the support system that gets you to the finish, whether that's six people at five aid stations, or just you, better organized than you'd be on your own.
It's free, because I'd rather build something every ultra runner can actually use than gate the thing that might be the difference between finishing and a DNF.
