Watching some of the highlights and I'm a bit confused. It isn't just MSR either it happens in other races.
There are riders quite clearly suffering in the cold, normally the hands. I don't want to sound like their mum's but why don't they dress properly?
Surely with the worlds best cycling kit makers lining up to sponsor them they can find a decent set of gloves that would keep them warm and not impact on there riding? Gabba gloves?
I know it is hard to get kit right for racing, especially over long distances but it is not like they are a bunch of 4th cats or don't have the resources (team car, domestiques?) to put in extra layers as the weather changes.
