Minutes per km only?

No ability to change pace to minutes per mile?

Helped me reach PR is Chicago

This app definitely helped me reached my PR! I run with my phone (doing so for years) with the tall building my GPS watch is off... I tracked myself on the app. After crossing some of the timing mats I checked the app. It shows your estimated time at that pace. I knew when to slow my pace or pick it up. Was kike my own personal pacer!

Tracking my friend - Great

(1) The setup procedure was quick and easy
(2) The tracking map was spot on. It had my friend tracked that we had no problem spotting him and cheering him on.
(3) I was able to switch the map from Ks to miles

A special thanks to the developers of this app.
