We give you a genuinely good coach, proven in the AI Thunderdome.
No subscription, no upsell, no ads. Bring your own AI key and a plan costs pennies, or nothing at all with the free models. We run on coffee money.
Coggan zones, CP/W'-individualized intervals, polarized periodization, heavy strength, durability work, heat prep, and a curated library that grows as new sports-science research lands every week. A real coach's logic, not a chatbot guessing.
Plans flow through intervals.icu into the apps and headunits you already ride. We do not reinvent the wheel, we point it downhill.
FREE AI TRAINING PLANS · CYCLING, ROWING & RUNNING
Plans push through intervals.icu and land wherever you train. Connect once, ride anywhere.
Not a chatbot freestyling intervals. Every plan is shaped by a deterministic science engine, then graded against the peer-reviewed literature. Here's some of what's baked in, and it keeps growing as the weekly research scan pulls in new studies.
Don't take our word for which AI builds the best plan. Watch them fight for it. Send your goal into the Thunderdome and a field of vetted models each builds you a complete plan, in parallel. Every plan is then scored scientifically against the sports-science literature, so you can see, not guess, which coach got it right.
Heavyweights and dark horses alike, including free models that punch well above their price. Generate your perfect plan and find your favorite AI coach.
I built this to help train the athletes I coach, my kids, and myself. Figured someone else might like it as well.
If it makes you faster, drop a coffee in the bottle.
