Most athletes plateau because they're leaving efficiency on the table, levers that don't show up in watts, pace logs, or weekly volume. Grepiac surfaces them. Turns them into race-day strategy.
Watts, pace, and Load only get you so far. Most athletes plateau not because they can't push more, but because they're leaving free seconds and watts on the table in technique, position, fueling, and race-day execution.
Those gains are invisible at first glance. They live in calculators, in technique observations, in equipment audits, in race-execution analysis. That's what we surface, and what we turn into action.
Grepiac is built for triathlon coaches running rosters of serious athletes, and for self-coached athletes who want lab-grade analysis without paying for a coach. Same platform; the audience determines depth and access, not which tools are unlocked.
Grepiac is built around four areas where coaches can move the needle, and where most other platforms either don't go, or stop short.
The analytical depth coaches actually want, surfaced in plain English. Calculators, metric history with regression detection, technique assessments, lab tests, sport-specific deep dives.
Pre-race planning to post-race learning, end-to-end. The race plan is built once, simulated, validated for feasibility, and then reflected on afterward to feed the next cycle.
The qualitative half of performance, made structured. Technique observations for swim and run; equipment changelogs for bike, shoes, wetsuit, kit.
The infrastructure for coaches running their roster inside Grepiac rather than spreadsheets, multi-team, assistant-coach hierarchy, subscription lifecycle, macrocycle templates.
Grepiac sits alongside your training calendar, not instead of it.
The schedule lives where you put it. The understanding lives in Grepiac.
Athletes upload their workouts (FIT or TCX), Grepiac enriches them with calculator-driven insights, technique flags, and race-context analysis. The training calendar itself stays wherever your coach already runs it (TrainingPeaks, Final Surge, a spreadsheet). Direct workout export to TrainingPeaks is on the roadmap so coaches who author structured workouts in Grepiac can push them to TP for delivery.
