This Chrome Extension calculates your “total running pace” based on the total time and total distance, rather than moving time and distance. It then displays it in your activity’s statistics panel (on the overview page).
This is extremely useful when training for trail events like ultra-marathons where you’ll be refilling water bottles and be standing still, but the race clock keeps ticking.
The extension is run only when you’re on the actual Strava activity page. Being a simple extension, it doesn’t store any data (apart from being on or off) and doesn’t send it anywhere.
Have fun
