Fitness Apps Suck

Or if you're suddenly going from your walking pace to 20-30-65-75MPH, you probably aren't the fastest human on the planet. You got on a bus and forgot to turn the darn thing off when you reached your bus stop. Just like most of the tracking apps have an "auto-pause" feature for when it looks as if you're taking a breather, they should have a settable max point where it will break the activity into a separate segment when you're clearly going faster than you can make yourself go.

Also, skip the UI sugar for the main purpose - TRACKING - of your app. If I want a map, I'd click over to the mapping application to see where I am. It should start quickly and start recording quickly, possibly notifying me that while it can trivially determine my location from the wealth of Wi-Fi signals permeating the campus, it's going to throw up a modal d-box and demand a click from me b/c the GPS doesn't get an immediate fix when they turn it on until you've made three taps into the program.
