Meet Leo, your AI running coach

What is Coach Leo?

Coach Leo is an AI running coach application at coachleo.ai. It connects to your Strava account and builds your training plan from real data — your actual paces derived from 8 weeks of activities, not generic templates. Leo uses 11 specialized coaching tools and a scientific knowledge base of 65+ peer-reviewed papers to make coaching decisions autonomously, like a real coach with access to your training diary.

Leo has persistent memory across sessions. He remembers your training history, past coaching decisions, injury setbacks, shoe mileage, race goals, and what you discussed last Tuesday. Every recommendation builds on what came before — Leo never contradicts himself. After 3 months, he has a detailed coaching dossier that creates real switching costs.

Leo supports running, trail running, cycling, mountain biking, and nordic skiing. Cross-training sessions get specific roles (recovery, aerobic, strength, prevention) and are integrated into your weekly load. Whether you are preparing for a 10K or a 100-mile ultra trail, Leo adapts daily through conversation — based on your body signals, your schedule, and your life.

12 features that make Leo different

1. Strava-First Coaching — Leo never asks 'what's your weekly mileage?' — he already knows. Strava syncs every 30 minutes. When you open a conversation, Leo has already analyzed your last 10 activities, your training load trends, your acute-to-chronic workload ratio, and your weekly patterns.
2. Plans Built From YOUR Actual Paces — Leo derives your easy, tempo, interval, and long-run paces from 8 weeks of real Strava data. No generic templates. Your Zone 2 pace comes from YOUR heart rate and pace distributions.
3. Plans That Fit Your Life — Hard constraints are enforced, not just preferences. 'I can only run Tuesday, Thursday, and Sunday', 'maximum 40km per week', 'no interval sessions' — Leo respects these in every plan.
4. Multi-Indicator Overtraining Prevention — Leo never relies on a single metric. He cross-references ACWR trends, volume increase speed, rest days, subjective fatigue, recurring body signal patterns, and plan adherence rate.
5. Biomechanical Shoe Wear Analysis — Not just mileage tracking. Leo inspects 6 wear zones with visual scoring. Wear patterns reveal biomechanical signals — pronounced medial wear suggests overpronation.
6. Race Preparation With Web Search — Say 'I'm doing the UTMB CCC' and Leo searches the web for real race data: date, distance, elevation, terrain, participants, GPX file. No manual entry.
7. Sports Nutrition Guidance — Evidence-based race fueling adapted to your weight, duration, elevation, and gut tolerance. IOC/ISSN guidelines applied per session duration.
8. Scientific Knowledge Base — 65+ peer-reviewed papers with hybrid semantic search. Every recommendation must cite sources. Covers training methodology, overtraining, biomechanics, nutrition, psychology.
9. Persistent Coaching Memory — Leo searches past history before advising. He references specific conversations and never contradicts past decisions. After 3 months, Leo has a coaching dossier no new app can replicate.
10. Race Time Predictions and Training Zones — Race time predictions (5K, 10K, Half-Marathon, Marathon) from a 4-model ensemble (VDOT, Tanda, Cameron, Riegel) dynamically weighted by your profile. Trail-adjusted estimates for specific races. Pace zones (Z1-Z5, Daniels) and HR zones (Karvonen) derived from the same VDOT — the dashboard, the coach, and the plan all see the same numbers.
11. Running Character System — 9 animal archetypes computed from 9 real training dimensions — not a personality quiz. Calculated from your Strava data. Evolves through 3 stages as you train.
12. Cross-Training as Strategic Lever — Cycling, swimming, hiking, skiing — each session gets a specific role: recovery, aerobic development, muscular reinforcement, or injury prevention. Integrated into weekly training load.
