What athletes are saying
I cut 13 minutes off my race time and qualified for the Boston Marathon by following my recommended pace from the Tyme Wear app.
Testing my threshold and knowing where I stood gave me the confidence to push beyond what I thought I was capable of.
Amazing product! The Tyme Wear app predicted my race time weeks before I was even on the starting line.
