Decent function with some very weird quirks.

Over all this is a decent app. Individually tracking 40,000+ is impressive.

The disappointment is that the claimed tracking isn't real-time tracking. It's an estimate with check-in points every 5 k.

That brings me to the second strange quirk. It's in Chicago (which uses Imperial measurements), it's advertised as a, "Marathon" (which is 26.2 imperial miles) but the check in points are metric... Like it or not, 90% of American users will not be able to visualize the metric distances and be able to tell where the competitors are on the track.

Finally, the app insists of zooming back to my location on regular, 30 second intervals without prompting. As I'm scrolling around the map to see the runner or locations, I would just locate the desired information and the app would zip back to my location. I'd have to go back on the scroll hunt for the information I desired.

Basic functionality is good, just some weird things going on in the minds of the developers.


First Time "Marathoner"

We were thrilled that this app worked so well --- spot on after the 5K point which helped tremendously. It really didn't "locate" our runner on the map until then. It would be nice if splits could be viewed in miles or kilometers. As a first-time spectator we would have LOVED a spectator "viewing route" where it could tell us where to go and how to get there based on our runner's pace. Maybe even preload an anticipated pace to get recommended viewing points!


Marathon tracking

I ran my first Chicago marathon this weekend and the app missed me at the starting line and the 15K mark. This caused stress for my husband and kids that were tracking me and then the app reported a time of over an hour slower than my true finish time. It tracked my friends that I ran with just fine the whole way. But I had heard reports that happened to others. My time is correct on the race website but it’s been 2 days and it’s still wrong on the app. I hope it gets fixed as I trained so long for this race.
