Decided to go out for an ambient 3.5k run, deliberately much shorter than usual to avoid any aches.
Was a good plan except MapMyRun played up and squiggled off on its own route (and thought I was on a bike) and when I checked I’d only actually done 2.65k. Pffff.
However it was ambient and quite relaxing run so a success of sorts! It seems that the app is more liable to screw up if the phone battery is low and/or there are more people around, or am I imagining it?
