It ain't on the profiles, but Pinkie canonically walked through the wilderness with her friends, without stopping.
Also without sleeping too.
I'll also point out that merely riding a train from Ponyville to Appaloosa takes 26 hours. And this is a lowball considering that timer started with them
in the desert. Meaning just a single small portion of the country takes a day. Who knows how many days it took them to walk south from Ponyville, all the way to the bottom of the continent? Without stopping, or sleeping?
This is their map for reference. Oh, and Klugetown is located near the end of an even bigger desert.
All I'm saying is, a almost a weeks worth of non-stop walking, through 2 deserts no less, is probably a better stamina feat than fighting for a day.
