What is Flow State Endurance?
Flow State Endurance is an AI training calendar for endurance athletes. You set a race goal, and it builds a plan that balances your key sessions, recovery, and training load, then rebuilds the week when life gets in the way (travel, a missed run, a bad night of sleep). It pulls in your past activity by importing history from Strava and Garmin, so it can read where your fitness actually is before it plans anything.
The integration is a one-way history import, not a live two-way sync. Flow State reads your past activities to understand your load and readiness. It does not write activities back to Strava.
Key Features
AI planning and replanning. On the Coach tier, you talk to it in plain language and it creates or adapts a marathon or triathlon plan. Tell it your non-negotiables and availability, and it reorganizes the calendar around them instead of forcing you onto a fixed template.
Structured workout export to Garmin. It turns a key run into a Garmin-ready workout with warmup, reps, recovery, and cooldown already built. Push it to your device and run it as prescribed.
Training signals. The dashboard tracks load, readiness, HRV, sleep, and recovery context so the plan reflects how your body is actually doing, not just the calendar.
Plain-language explanations. When the AI moves a session or changes your week, the Coach tier tells you why in normal words instead of leaving you to guess.
Custom agent access via MCP. Coach includes Model Context Protocol support, so you can point your own AI agents at your training data and build custom workflows on top of it.
Who it's for
Flow State Endurance is built for endurance athletes training for a goal race, with marathon and triathlon plans called out specifically. It fits people who already use Garmin and want a calendar that adjusts to a real schedule instead of a rigid PDF plan. The free tier covers the calendar, builder, signals, and device exports, so you can run the whole thing without paying. The Coach tier is for athletes who want the AI to do the planning and adjusting for them.
