Compare
How Nordik Lab compares to TrainingPeaks and Final Surge.
Same planning, analysis, and analytics you'd expect from a training log — plus an AI-native workout builder and a direct line from ChatGPT or Claude into your real calendar.
Smart Add
Type the session. It comes back structured.
“4×5 min Z3 run” becomes warmup, work, recovery, and cooldown blocks with duration and projected load — no manual builder required. Neither TrainingPeaks nor Final Surge offer an AI note-to-workout builder like this.
MCP tools
Plan from inside ChatGPT or Claude.
Ask your agent to check readiness, move a session, check race-week load, or build a full multi-week strength program — it edits the real calendar through Nordik Lab's MCP connector. This is a new category — legacy training logs don't have an agent-native way in.
Training Absorption
Know how well your body took the session, not just what you did.
An HRV-based absorption score, grounded in published research (Plews, Laursen, et al.), tells you how well you recovered from a workout — not just that you completed it.
Wind analysis
Every route, corrected for the wind you actually rode or ran in.
Hourly wind data interpolated against your GPS track gives a wind-adjusted pace, headwind/crosswind/tailwind split, and pace-cost — built into every outdoor session automatically.
