ATHRON
Coach for marathon & triathlon
Only for iPhone
Free
iPhone
ATHRON is your Decision Coach for triathlon, running and cycling. Instead of just showing plans, ATHRON decides with you every day: What's the right training today? Why? And what changes when recovery, sleep or life demands it?
Adaptive plan, not rigid cycles
Your training plan isn't a document. It's a continuous decision. ATHRON adapts day by day based on HRV, body battery, sleep, life load and your race goals.
TODAY: one decision, three modes
- Quick: What now? One sentence, one action.
- Coach: Decision + reason + next step.
- Analyse: Context, data, trade-offs.
Integrations without coercion
ATHRON works fully without any integration. Garmin, TrainingPeaks, Intervals.icu, Oura, WHOOP, Withings are additive data layers — not required. You decide which source leads.
Data sovereignty
Your health data stays in the EU (Hetzner Frankfurt). No sharing with training-data brokers. No ad tracking.
Honest empty states
No fake coaching, no fabricated numbers. When data is missing, ATHRON says so — and what the next step is.
Who it's for
Triathletes, runners and cyclists who want to plan like a coach, not like a calendar. Intermediate to advanced level.
Subscription
Free 30-day trial. Then ATHRON Pro: 19.99 EUR/month or 199 EUR/year (two months free). Cancel anytime. No ads, no trackers.
ATHRON is your decision layer. Not another data-dashboard app.
