Barely functional enough to avoid 1 star

No way for runners to truly claim a profile, defaults to kilometers with no way to convert to miles, live tracking not very functional, no way for trackers to share real-time messages with runners, and no (easy) way for runners to access messages sent. And it wasn't even released until 3 days before the race. Expected much more from the official app for a world major

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.

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!
