The TrainingPeaks alternative for endurance athletes and coaches.
Smart Add
Write the session. Get a structured workout.
Write “4×5 min Z3 run” and Smart Add builds warmup, work, recovery, and cooldown blocks with durations and projected load. Edit the result before you save it.
Smart Strength
Write the strength session. Get an editable workout.
Describe the sets, reps, and load — or just the intent — and Smart Strength builds an exercise-by-exercise strength session from the library, or a full multi-week strength program.
Dynamic plans & reusable sections
Plans that live on your real calendar, not a generic template.
Dynamic training plans stage phases, weekly targets, and strength work against actual calendar dates. Save any block or week as a reusable section and reapply it instead of rebuilding it.
MCP tools
Plan with ChatGPT or Claude.
Ask ChatGPT or Claude to check readiness, move a session, review race-week load, or build a multi-week strength program. Nordik Lab applies approved changes to your real calendar through its MCP connector.
Training Absorption
See how a session landed.
The HRV-based Training Absorption score estimates how well you adapted to a workout and puts the result alongside your fitness, fatigue, and form.
Wind analysis
Account for the wind on every outdoor session.
Nordik Lab matches hourly wind data to your GPS track, then shows adjusted pace, time spent in each wind direction, and the estimated cost of the wind.
