ComboPower estimates your running power and VO2max in real time — no external
power meter required.

How it works

ComboPower combines three physics-based power components using your GPS speed,
elevation, and heart rate:
- Rolling resistance — your weight and pace
- Air drag — your speed relative to the wind (set your local wind speed
  and direction as a field setting for more accurate results)
- Climbing power — the current grade, with an efficiency correction for
  steep uphill/downhill

The result is smoothed in real time and shown alongside your session and lap
averages, plus a live VO2max estimate corrected for ambient temperature.

What you see
- POWER — current estimated power (W)
- AVG P — session average power (W)
- LAP P — lap average power (W)
- VO2MAX — live VO2max estimate (ml/kg/min)

After your activity

Power and VO2max are written directly to your FIT file, so they show up in
Garmin Connect and any FIT-compatible analysis tool.

Setup

Enter your weight in the data field settings (two fields: tens + ones digit,
e.g. 7 and 2 for 72 kg) — that's it. No pairing, no external sensors.

Please note

ComboPower's power values are a physics-based *estimate* derived from GPS
speed, elevation, and heart rate — not a direct force/torque measurement from
a dedicated power meter. Accuracy depends on GPS signal quality and course
conditions (tunnels, dense tree cover, or erratic GPS will affect the
estimate).
