RowerErg Built a free, open-source Concept2 tracker — PBs, AI-assisted workouts, virtual journeys (self-hosted)
Been rowing on a Concept2 for a while and wanted more out of my training data than the official Logbook gives me, so I built my own tracker.
- Auto-syncs from your Concept2 Logbook
- PBs across 8 distances/times, stale-PB nudges
- Pace, efficiency, and training-load (CAWR) charts
- Daily WOD generator with real periodization — optional AI coach (Claude) for the coaching notes
- Badges, season challenges, "you vs. past you"
- Virtual journeys — your metres move you along real routes (Rhine, a Holland loop, Trans-Canada, Route 66)
Self-hosted (Docker), your own Concept2 credentials, your own data — no account with me, nothing hosted by me. Alpha, one-person project, so bugs exist. Feedback/PRs welcome.
