For a change I ran 12km on the road this morning. The route through Totley and Dore used to be my regular winter Tuesday evening run but for some reason I stopped. I think I felt it was too long to run fast and too short to run slowly. Either way it's quite a challenging route as although it's tarmac the whole way the central 2.5km has 100m of gradual ascent. It doesn't sound much written down but it is quite an effort.
I was pleased to complete in a shave under an hour which is benchmark for having made an effort on the route. I once managed 56 minutes but that was a chance event!
I've used the timings to reset my pace analysis on Strava as today's pace was in VO2 and anaerobic zones for an unfeasible time.
