All hail the mighty Strava.

So far this month in the distance challenge: 247,394 riders have ridden a total of 116,947,484 km (472.71km or 293.73 miles per rider)

In the elevation challenge: 193,766 riders have climbed a total of 1,206,966,819 metres (6,228.99m or 20,436.35 ft per rider).

This works out to an average of 13.177 metres gained per km or 69.57 ft per mile.

So for a 20 mile ride the average elevation gain for all strava riders would be 1391.5 ft so you're a bit under that figure.

Now, how accurate is the elevation gains on Strava? Good question.

For fun, my average gain per mile this year is 72.60 ft and this is using a Garmin 500 GPS with altimeter data.
