# DataFrame™ (https://sports.zurrieq.com)

> Free training analytics for endurance and hybrid athletes. Syncs Garmin Connect (and optionally TrainingPeaks / Garmin Coach / Google Sheet plans) into one athlete-owned dashboard for recovery-aware decisions.

DataFrame is **not** a replacement for Garmin Connect or TrainingPeaks. It is the decision layer on top: whether today's hard session still fits overnight recovery, and whether interval *quality* is trending the right way.

Not affiliated with Garmin, TrainingPeaks, Peaksware, or other fitness brands. Non-commercial personal project.

## Pitch

Garmin tells you what you did. TrainingPeaks tells you what was planned. DataFrame tells you whether today's plan still fits your recovery — and whether the quality of the work is trending the right way.
