I recently saw an article on iOS development, explaining the maps features available to developers. I had never realised it was possible to enable in an app the 3d views you see in the apple Map app. A little bit of fiddling later and you can now see your course in gorgeous 3d views if you have an iPhone that supports it and your city is covered by the feature.
I haven’t really yet figured out how it can help you with training or analysing your data better, but it looks great and is a pretty neat way to relive some of your runs or rides, so here it is available in connectstats 2.5 (under review by apple at the time of this writing)
