What Ergon is and how your workout data gets in.
Ergon is a training platform for Concept2 ergs. The mobile app is the product; this site covers the questions that come up while using it.
Two ways data gets in
Concept2 Logbook sync. Connect your Concept2 account and Ergon pulls your workouts from the Logbook — history first, then new workouts as they appear. See Connecting Concept2.
Direct PM5 capture. Pair your erg's PM5 monitor over Bluetooth and Ergon records the workout live — splits, stroke data, heart rate — without waiting for a Logbook upload. See Pairing your PM5.
Both paths land in the same log. If the same workout arrives twice — captured live, then later synced from the Logbook — Ergon merges them instead of creating a duplicate.
Your account
Ergon accounts use email and password. Concept2 is an optional connection, not a login method — you can use Ergon without ever linking it, though most of the app is built around your erg data.
