Blimey Claire, that'd be a step too far for me. A lot of steps too far.
Hope it works out for you though. Gill looked at doing it the year before last, & it all looked great fun, but then she injured her back & had to quit jogging.
aw that's a shame - I actually found taking up running helped my back problems no end, but presumably different issues. I hope Gill has found some other form of exercise to replace it. I don't do a lot, but would be mightily peed off if the decision *whether* or not to get off my bum was taken out of my hands
