Actually, it was only meant to be 7 days, 4 runs and 40k, but, annoyingly, I got the start date of the challenge wrong and so the first 10k didn't actually count towards the challenge. I wasn't going to let that get in my way though, so today, with rather weary legs, and between the showers, I set off to complete the challenge and run the final 10k.
Having had a quick recce earlier, the problematic riverside stretch that I ran on my first ever 10k turned out to be no longer submerged, so I decided to rerun that first 10k run from 1 July 2019.
So, despite it being decidedly squelchy in places and my poor trails shoes having had another 350km on them in the intervening year, the difference between then and now was just over 15 minutes.
Now, I think, I'm going to give my legs a couple of days off while I work out my next challenge.
