It's obvious how it tracks a run, using SatNav. But I'm dubious about it's accuracy when it measures elevation. Anyone know how it's done?
Second point is, why does any path in front of you look uphill, even when you run it and then turn around and retrace your steps? Ah, the mysteries of the universe!
Did my longest run yet this morning (business got in the way yesterday, and I didn't get to ParkRun after all!) of 9.2k, but I'm getting slower and slower. I have no doubt that I could do 10k tomorrow, but maybe I'm more suited to shorter distances. So when I've done the Bristol 10k in May, and a Run for Life in September, I think that'll be it.
Oh, and I need to mention my bargain Asda £10 trainers, that seemed a bargain. They've started to hurt my feet after 5k or so. So not such a bargain, and I'll go back to my old, battered New Balance that don't hurt!
