VO2 max, maximum volume of oxygen in milliliters consumed per minute per kilogram of body weight at maximum performance, averaged 50 for Garmin runners. Garmin also averaged 4.82 miles per run and 73 sleep score, while Strava ranked running first and loads do not compare directly.
Garmin builds Training Status from VO2 max trend plus recent load. Strava builds Relative Effort from heart-rate zones and Fitness and Freshness from chronic and short-term load. Pick one platform for trend decisions.

What VO2 Max and Training Load Mean
Garmin's Edge 830 manual defines VO2 max as an indicator of aerobic fitness that should rise with training. A higher number means the body consumes more oxygen at maximum effort.
Garmin support calculates Training Load as the sum of excess post-exercise oxygen consumption, called EPOC, from the last 7 days. EPOC reflects oxygen debt after hard effort. Higher load signals higher intensity and greater recovery need.
What Training Status Tells You
Garmin Training Status combines the VO2 max trend with recent training load. It uses Firstbeat Analytics methodology to label current training.
Labels are Productive, Maintaining, Unproductive, Strained or Detraining. Productive points to fitness moving the right way for the load done. Strained or Unproductive points to load outweighing fitness gain and need for rest.
How Does Strava Score Effort?
Strava describes Relative Effort as a score for each activity from time in personalized heart-rate zones. Higher-intensity time counts more, so a short hard run can outscore a longer easy ride.
Strava Fitness and Freshness tracks Fitness as chronic training load and Fatigue as short-term load. Form is Fitness minus Fatigue. RoadCyclingUK reporting explains the chart is used to anticipate peaks, valleys and race readiness.
- Garmin load: 7-day EPOC sum, tied to intensity and recovery need
- Strava effort: zone-time score, weighted toward hard minutes across sports
- Garmin status: VO2 max trend plus load, labeled Productive to Detraining
- Strava form: Fitness minus Fatigue, used to time peak or rest
What 2026 Runner Data Show
Garmin reports in its 2026 global running and cycling data report average run distance of 4.82 miles, average runner VO2 max of 50 and average sleep score of 73. The half-marathon was the most-used Garmin Coach plan.
Strava reports in its 12th annual Year in Sport report running remained its top sport with racing rising. Runna-connected data showed 26% beginner and 34% intermediate runners with 86% logging a personal best in 2025.
Why Watch Numbers Need Caution
A PLOS ONE validation study by Lambe and colleagues found Apple Watch underestimated VO2 max versus lab indirect calorimetry by 6.07 mL/kg/min on average in its watch accuracy study. Mean absolute percentage error was 13.31%, so single readings can miss by a wide margin.
Garmin and Strava figures cover only device owners and subscribers plus a 30,000-person survey, not all runners, according to Strava 2025 methodology described via Seasons Run Club. Garmin EPOC load and Strava heart-rate load use different inputs and are not interchangeable. Follow trends on one device and one platform rather than comparing absolute scores.
