I watched a bit of it earlier this evening, I know it's very different to running, but I'm sure I remember Angela Bell(??) being in Runners World magazine, as a marathoner??
So, maybe she has the fitness, but it's the techniques/adaptation?
Amy Williams should do fairly well, I'd guess??
I am happy, in a way, that they state how hard it is, as I'm sure we all know 'armchair experts' who tell us that riding up a hill can't be that hard
