Actually, I think it rather more likely that it was a genuine and helpful attempt from an incredibly genuine, helpful and knowledgeable poster to offer one other possible cause for MsCharly's discomfort, with a nod at forum humour about the sensitivity of the subject.
And anyway, if memory serves it would be a non-issue because I'm pretty sure that no helmets were involved in the creation of that particular nexk discomfort on that particular ride.
MrCharly, is your girl still enthused for getting further once the warm fuzzy glow of having got round (and THOROUGHLY trashed her big brother's longest distance ever
) has started to fade?
