Rat Race hold a variety of events which involve elements of cycling, orienteering and obsactle courses This year they are running a London to Edinburgh sportive for instance.
Just for fun, I took a single run at Victoria Street, 5.3 miles into a ride yesterday and managed it in 41 seconds. I wasn't going all-out by any means so it was a poor time. I did get a bit of wheelspin even on the dry setts (we don't have cobbles in Edinburgh). If I decide to take it seriously, I'll need to shave a whole lot off that time.
I'd have done a few more runs but the standard of motorists and pedestrians left a lot to be desired (although Victoria St itself was clear) and put me off looping round again.
As for Danny McAskill, he's a name in Scottish cycling and that's what it's all about - being pitted against a random opponent. So what if it's Danny, David Millar or Jimmy McLeod from a local branch of Greggs?
