This is the first time in 15 year that someone's canceled Smashrun Pro because they're boycotting American companies.

We've updated Smashrun's heart rate zones. There's a new <60% zone and the Max zone has been shifted down from 97 - 95%.
Also, the colors have been adjusted a bit to better match the "feel" of running in these zones.
