I reckon the complete offroad route (which works out at approx. 1200 miles) could be done in 10 days for people pretty fit – if you were race fit then I reckon you could do it in 9 but it would be a serious attempt.
120 miles offroad each day – the route suggested on the CTC site sounds fine but it will be very tough. CTC link here.
I'm using it as a target for 2011 as I fancy giving it a bash. For some bizarre reason, I don't see the appeal of taking my time to ride the distance – saying it took me 4 week to ride it just seems very flat (in my head I reckon anyone and everyone could do the ride if time wasn't an issue). However, putting a time limit on it seems to appeal to me…and I don't know why as I'm not in the slightest bit competitive.
Anyway, I was thinking of trying to get myself into some sort of shape for an attempt next summer…in 10 days to cover the 1200 miles – but I'm incapable of surviving 40 miles just now so there is a shed load of work to be done to even get close to doing this…
