What is PersonalBestPace?
PersonalBestPace is an AI cycling coach built for riders who train with power. It pulls your rides in from Strava, models your fitness over time, and writes a periodized plan that adjusts as your form changes. This is a cycling-specific tool, not a general running app, and a lot of what it does only makes sense once it has your power data to work with.
The app lives on the web at app.personalbestpace.com and on Android as "PBP - AI Cycling Training." There is no iOS app. It's run out of the Netherlands and bills in euros: the free tier covers tracking, and Premium is €4.99 for your first month and €11.99 a month after that.
Key Features
CTL, ATL and TSB fitness modeling
It tracks the classic training load picture: Chronic Training Load for fitness, Acute Training Load for fatigue, and Training Stress Balance for form. On top of that it follows your FTP, your power curve across different durations, and TSS scoring, which it can estimate from heart rate if you ride without a power meter. This is the data the rest of the app builds on.
Coach personas you pick
Rather than one voice, it ships several AI coach personas with different training philosophies — a data-driven one, a polarized-training specialist, a motivational one — and you choose which writes your sessions.
Adaptive periodized plans
Instead of a fixed block you follow to the letter, the plan reshapes itself around your schedule and how your training is actually going. Miss a session and you can skip, swap or reschedule without the plan falling apart. Premium is where the AI weekly planning and the deeper periodization live.
Execution scoring
Each workout is scored against how closely you actually rode it, across power, duration and zone compliance, so you get a debrief on what to change next time rather than a green checkmark for finishing.
Strava and Garmin sync, including write-back
Rides land automatically from Strava and Garmin on the free tier, with no manual entry. It can also write your findings back into your Strava activity descriptions.
Who It's For
- Self-coached cyclists who ride with power and already know what FTP and TSS mean
- Riders on a heart rate monitor, since TSS is estimated without a power meter, though most of the depth here is power-first
- Not runners or multi-sport athletes — this is cycling only, by design
- If you ride for fun and don't track numbers, the free tier's performance tracking is the only part likely to land
