In my many years of D of E supervision I solved almost all the medical issues by feeding chocolate followed by a muesli bar to kids who simply ran out of steam as they had not eaten and were not fit.
The more serious ones all recovered after a hot chocolate and a flapjack.
Blisters were pretty much the rest of it.
