We analyze every climb, descent, and technical section of your specific race. No more generic training.
AI Builds Your Plan
Up to 20 weeks of course-specific training. Hill repeats that simulate YOUR race segments exactly.
Train With Purpose
Every session references actual km markers from your course. Not generic mileage or generic heart rate zones.
“Week 12: Long run 25km. Easy pace.”
Week 12 Saturday: 25km trail with 800m gain. Full race vest + nutrition practice.
📍 Simulates km 0-10 gradual climb and km 30-40 steep descent
One is a template. The other knows your course.
This is what a $200/month coach tells you.
No $10/month app does this.
The Science
Not a chatbot with a nice UI.
Every plan follows a peer-reviewed methodology with 50+ rules, 8 training pillars, and automated validation. Here's what's under the hood.
Your Course, Decoded
We analyze your GPX file into 4-6 key segments — steepest climb, longest descent, technical sections, final push. Every workout simulates a specific part of YOUR race.
Each plan references actual km markers from your course
8 Pillars. 50+ Rules. Peer-Reviewed.
Our methodology draws from Seiler's polarized training, Johnston & Jornet's Uphill Athlete framework, and the latest sports science. Every rule has a citation.
Built from 50+ peer-reviewed studies

Base → Build → Peak → Taper isn't just labels. Each phase has scientifically calibrated intensity rules that shift from pyramidal to polarized — because that's what meta-analyses show works.

Your Body, Not a Template
First ultra? 8+ weeks of aerobic base. Veteran runner? 4-6 weeks is enough. Weak on descents? Eccentric training every 14-21 days. The plan molds to your experience.
Experience-tiered progression based on training science
Coach-Checked. Automatically.
Before you see your plan, it passes through an automated coach validator that checks every rule — from taper gradients to fueling protocols to intensity distribution.
50+ validation checks per plan

Your body isn't a machine that performs the same every week.
STI gets that.
For women runners: turn on cycle-aware planning and your training schedule works with your body's rhythms, not against them. Key workouts land when you're strongest. Recovery weeks align with when you need them most.
And if your cycle throws a curveball mid-plan? One tap to adapt. No guilt. No lost fitness. Just a plan that flexes with you.
No pseudoscience. No rigid phase calendars. Just smart adaptation based on how you actually feel.
Proactive
Recovery where it helps
Recovery-friendly structure lands where tougher weeks are more likely to feel heavy, while key work stays protected.
Reactive
Adapt when symptoms hit
Lower energy, cramps, rough sleep. Adjust this week and the next stretch without throwing the whole plan away.
