I found some running buddies on this app, might help you out. The app is free, for iOS.

I didn't know there was one either, until I was surprised to learn about it. I may do the Christmas Cracker, but it may get in the way of the festivities. What was the route like for Bristol?
I hadn't run since leaving school a few decades ago. On Wednesday evening my wife returned from her running club and I suggested we go out for a short interval session to gauge my ability. Did 8 x 1 minute run: 1:30 minute walk intervals and thought ' that was easy' so was encouraged to sign up for my local Parkrun this morning.
Mrs SG set me a target time of sub 26 minutes so was very pleased to come in 56th out of 281 and get a time of 23:43.
I don't have any running gear so am currently browsing on Wiggle lol.
First track session in gawd knows. 5x4minutes...you run one way for two minutes, the klaxon sounds and you run back to cross the line you started from before the klaxon sounds again(!)
Weird, but a decent work out.
