I recall when Wiggins won in 2012, it was mentioned how much weight he had lost (Google reportss in the region of 6kg - so I would suggest that PFP's 4kg, taking their comparative body weights into the equation, is a very similar percentage of their original weight) and I recall it being hailed more as a great effort, and I don't recall anyone saying it was dangerous or might encourage any budding cyclists to do the same.
Latterly he said I think he was down to something like 4% bodyfat, and it was on the verge of being dangerous, but he did what he had to do to take home the 2012 title, and latterly went back to a more natural weight, which I am sure PFP will do as well - I think she has already stated that.
He was a skilled sportsperson, PFP very much still is, and they both made strategic decisions about what they wanted/needed to do to help them win the TDF.
Personally that seems pretty much common sense, hill climbers will target super low weight for the end of the year events etc.
With PFP it feels like they are trying to taint her win, not by saying she is cheating, but by saying she is doing something that maybe morally she shouldn't have done, which I personally think is wrong and casts a completely unfair shadow over her stellar victory.
And I say that as a PFP fan, but equally, and closer to home, a massive Kim Le Court fan as well.
I
really hope it has not detracted from the win for her.
I'm still disappointed that her colleagues in the peloton have seemingly waded in with very similar comments, rather than supporting her.
I believe she may be a slightly divisive figure (?) in the peloton, so maybe that has something to do with it.
I have to say I do agree with
@Cathryn - woman achieves something truly remarkable, what can we find to cast a negative light on it.
