Great app

Used the app in the U.K. to follow my daughter and her partner. It was excellent. Many thanks

Awful app

The map tracker should be geared towards spectators. The mile markers would sometimes appear and it was hard to find what mile our runner was at. The map showed the water stations… I’m sorry but runner is watching the map while they run. It needs to be geared towards the spectators trying to find their specific runner.

Distance is labeled as miles but it shows as km

When tracking runners on the graph tab, the units should as kilometers (42 km for marathon) but the label shows as distance (mi). Good to update.
