Hey everyone,
I’m a dedicated cycling enthusiast logging about 10,000 km a year (mostly on the flats of Netherlands, as you might guess!). Like many of you, I found myself wanting a training tool that sits right in the middle: more actionable than a standard data dashboard, but without the commitment of hiring a full-time human coach. Combining that need with my background in tech and the current advancements in AI, I decided to build exactly what I was looking for.
What started as a personal side project to track my power PRs has evolved into PersonalBestPace—an AI-powered cycling coach that builds adaptive, periodized training plans based on your actual, real-time fitness data.
What makes it different?
Most AI training tools hand you a generic, static plan and call it a day. PersonalBestPace is built entirely around the CTL/ATL/TSB model (the same fitness-fatigue framework used by platforms like Intervals.icu). This means the AI actually understands where your body is at in your training cycle, not just where a calendar says you should be.
- Adaptive Weekly Planning: Your upcoming workouts adjust dynamically based on your current form and fatigue levels, rather than sticking to a rigid template.
- Choose your goals and coach : choose both your goals and approach as it feeds your.
- Life gets in the way Either your train 6 hours per week or 16, it will help your through
- Chat-Based Coaching: You can talk to it like a real coach. Describe how yesterday’s ride felt, ask training questions, or request a workout tweak, and it responds with your actual data in mind.
- Garmin & Wahoo Sync: Direct integration ensures your ride data flows in seamlessly and automatically.
- Power Zone Workouts: Structured around your FTP, either from existing library or some special custom one like , daily specials
Where it stands today
The platform is live, actively being developed, and goes wherever you ride (available as a web app, PWA, and native mobile app). You can check it out at app.personalbestpace.com.
I’m building this as a solo founder and genuinely want some feedback,
there is 2 weeks free trial period and 5 euros for first month
Cheers,
Mert
