The next best decision. Always. Your coach decides with you every day: what is right today, and why. ATHRON is your decision coach for triathlon, running and cycling. Instead of just displaying plans, ATHRON decides with you every day: What is the right session today? Why? And what changes when recovery, sleep or life demand it? An adaptive plan, not a rigid cycle Your training plan is not a document. It is an ongoing decision. ATHRON adapts day by day based on HRV, body battery, sleep, life stress and your race goals. TODAY: one decision, three modes - Quick: What now? One sentence, one action. - Coach: Decision + reasoning + next step. - Analysis: Context, data, trade-offs. Nutrition that matches the training Calorie and macro targets that move with your training week โ€” hard days differ from rest days. Log meals by photo or barcode. Recipes that respect your taste, your diet and your allergies. Understand your blood work (Premium) Upload your lab report and see what it means for your training: trends over time, the link to load and recovery, concrete conclusions for nutrition and regeneration. Not a diagnosis โ€” context. Integrations, never mandatory ATHRON works completely without any integration. Garmin, TrainingPeaks, Intervals.icu, Oura, WHOOP and Withings are additive data layers, not requirements. 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 invented numbers. When data is missing, ATHRON says so โ€” and tells you the next step. Who it is for Triathletes, runners and cyclists who want to plan like a coach, not like a calendar. Intermediate to advanced.
