ENDURE: Cycling Training Coach

EVERY RIDE IS YOUR LAB TEST.
FTP and VO2max come from the rides you already do.

ENDURE is your coach and your performance lab in one app. It analyses every ride, on the smart trainer and outdoors through Strava and intervals.icu, and works out what a lab appointment would tell you: your FTP, your VO2max and where both are heading. You skip the ramp test and the 20-minute test. The AI coach reads your recovery, your training load and a short morning check-in, then tells you which session today should be. When you ride indoors, ENDURE drives your smart trainer through structured workouts: you connect the trainer, pick a workout and start riding.

We built the app because this is how we wanted to train ourselves: no game wrapped around it, just numbers you can trust and a coach who reads them.

START RIDING

• Works with Wahoo KICKR, Tacx, Elite, Saris, JetBlack and any FTMS smart trainer, plus power meters and heart rate straps over Bluetooth.
• Zwift Click, Play and Ride controllers are supported for shifting, so you change your target from the handlebar.
• Less than 30 seconds pass between opening the app and your first pedal stroke.
• In ERG mode the trainer holds your target watts, and smart smoothing evens out jumpy power data.
• If your phone crashes or the connection drops, auto-resume picks up exactly where you were.
• For days without a plan there is a free ride mode: type in your target watts and pedal.

STRUCTURED WORKOUTS

• The library is curated. Every structured workout has a physiological purpose, such as VO2max, threshold, sweet spot or endurance.
• Describe a workout in one sentence and the AI builds it around your FTP.
• You can import your own workouts. .ZWO, .MRC and .ERG files are read directly.
• The training calendar shows your sessions month by month.
• Before you ride, ENDURE picks today's session from your recovery score, your recent training load and a short morning check-in. You get one recommendation and two alternatives.

PROGRESS, ON THE SIDE

• ENDURE models your FTP and VO2max continuously from your recorded rides. You see where things are heading week by week instead of torturing yourself through an all-out test every eight weeks.
• The power profile shows where you're strong and where there's room, across all interval durations.
• The Potential analysis tells you what is holding your FTP back, your threshold or your aerobic ceiling, and which sessions work on it.
• Training load (TSS) and time in zones for power and heart rate are there after every session.
• Strava and intervals.icu are connected. Rides upload automatically, and on first launch ENDURE can import your ride history, so indoor and outdoor end up in one picture.

ANALYSIS AFTER THE RIDE

• Right after a workout, the AI reviews your session: did you hit the intervals, how clean was your pacing, and how much did your heart rate decouple from your power (Pw:HR)?
• Across your whole history, ENDURE spots trends, accumulated fatigue and the rides where something clicked.

IF YOU WANT TO GO DEEPER

• ENDURE is the first cycling app that lets you log lactate readings during the ride itself. From your values it estimates LT1 and LT2, with a confidence tunnel.
• The CORE sensor pairs natively over Bluetooth. Core body temperature and heat zones run live on the ride screen.
• Climbing Efficiency detects the climbs in your outdoor rides and calculates a climbing score based on VAM.

ENDURE is an Early Release and keeps growing. What the community asks for goes straight into the updates. Premium is free for 14 days with every feature included. After that, recording rides needs Premium.

Cycling training with ENDURE means structured interval workouts in ERG mode on any FTMS smart trainer, an AI coach that picks today's session, and FTP and VO2max estimates that update from every ride, indoors and outdoors.

Recent changes:
NEW
• Ride screen: redesigned with a large power readout, a zone scale up to 160 % FTP, interval cards and one chart for power, heart rate and the workout profile.
• Coach chat: works without a check-in. The chat asks for it in the thread and looks up your earlier rides when you ask about them.

Plus bug fixes and performance improvements. Thanks for every message.
