I did the Colne Valley MTB Challenge Yesterday, and ended up quite far down the field.
Overall I was about 1/3 slower than the winner. However on the thread on here, a couple of the fast guys have said they 3 or 4 times more miles per week than I have the ability to do. ie I can not afford the time out to ride a bike, so will never get that kind of mileage in.
So in terms of miles trained to time slower, I was actually quicker than them
OK I know its not as straight forward as that, and any graph wouldnt be linear, but I am sure some clever bods must have worked out a way of correlating finish times v. effort training to work out who would actually have one the race if everyone had done the same amount of training... or is that just defeating the whole point of bike racing ??
