Gutted is not a big enough word.
I did Parkrun this morning and beat my previous PB by 24 seconds - all well and good. BUT I am SO furious with Fatbitch. As I usually do, I kept an eye on my pace (rather than distance or time elapsed) to try and keep a consistent speed through the whole run. Pace was fast, but I put that down to some of it being downhill. Finished the 5k course, and the stupid thing says I've run 7.2k, so of course it thinks I'm Speedy Gonzalez!!
This calls into doubt my Thursday night run of 5k in 30 minutes. Perhaps it wasn't that at all. Seems unlikely, given that I've just done 5k (albeit on a much hillier course) in 42 minutes. I'm feeling demoralised and angry with technology.
