Beat my 10k PB on Sunday by about 20 minutes, my first sub 1hour 10k run, so pretty happy with that! I never intended to go for it and actually started out at a very slow pace, but each km felt more and more comfortable, I'd started off doing a 6:40/km, each split getting faster, ending on a 5:08/km. I was only 30 seconds off beating my 5km PB.
I'd hit a bit of a plateau recently but starting doing some interval training, I'm thinking it might be starting to pay off.
