Amanda isn't doing anywhere near the climbing. So where Amanda is doing the daily mileage of the race leaders, she's not trashing herself or going without sleep to do so. Similar to myself last year. When I was after the Audax points in 2007, I was riding at about the same speed as I was last year, except that last year I wasn't riding over the Welsh mountains every other weekend.
I agree that Amanda would be a contender on paper. I understand that she doesn't want to ride on roads with traffic, probably because of her very bad accident 5 years ago has scared her off. I expect that she'll do the whole year in the park she is riding in. It seems to be working very well for her in many ways.
