mapopolis does this, and can record all your information in GPS trails which can be clicked and viewed later.
Mapoplis is free, the maps used to cost money (but they went out of business and don't sell them anymore... abandonware?). Anyway, since the actual app is free before the maps, its perfect for stuff like trailblazing.
I use it on my motorbike to see how fast I was going after a trip because my speedometer is off.
Also used it on a boat once along the Hudson River to see where we came from and get back to our dock.
