Hmm, no idea, sorry.
I'm not really running this weekend. I'm doing a charity walk tomorrow, the main bit of the walk is apparently about 21 miles (it's more a getting from one place to another walk rather than something that's properly measured), but I'm also doing an extra 5 or 6 to get from the end where I'm going to park to the place where I can get the bus to the start. I may well run or jog that first leg, depending how much stuff I'm carrying (and if it's enough food to keep me going through 26 miles, that might be quite a lot

)
So I decided that as I'm effectively doing a marathon distance tomorrow, even if it's mainly walking, I wouldn't run today. Except I wanted to go to the shop, missed the bus and realised that instead of waiting 20 minutes for the next one, it would be quicker if I jogged down there. I had some old (retired) running shoes on anyway, so I decided to just set off. It was probably a bit over 2 miles, but I've not measured or recorded it as a proper run.
Hopefully the walk won't take too much out of me and I'll be OK to go to running club on Monday.
