At roughly 14.0 miles per week on this pair, it has about 244 useful miles left before hitting your target.

How it works

The estimate is simple. The habit is the hard part.

The calculator divides weekly mileage by rotation size, then compares the remaining miles on a pair with the miles that pair is likely to take each week. Treadly does this continuously after you connect Strava or Apple Health, so the estimate stays current after every run.

Current miles

Start with the mileage already on the pair.

Weekly load

Split training volume across the active rotation.

Target lifespan

Estimate replacement before the shoe fully fades.
