Today’s hike was over Ingleborough in the Yorkshire Dales and I managed to pause my Apple Watch and forget to restart when we stopped for lunch, so god knows what these figures and the map means. You can safely double the elevation gain, likely the calories too as I missed recording the hardest, most technical part of the mountain to climb, and I think I would probably add around two miles or so.
It was a grand day out nonetheless.
Incidentally, Apple Watch in its current iteration is a quantum leap ahead of the turd I bought in the form of the first generation model. Superb battery life and excellent functionality. I got home after recording this hike and the battery had depleted to 68%. My previous watch used to last three hours recording workouts. This is a huge improvement.
