Its fascinating how much conditions can play a part.
I only saw a few pictures and listened to a few post-race interviews, but I was really surprised to see what some of the top runners were wearing.
- Big billowing rain jackets in a head wind race!
- Completely bare legs
- Nothing on their heads - no tuques
It appears many of the race favorites succumbed to and suffered in the conditions. Those jackets that more than a few were wearing at the start, were acting like parachutes holding them back. Look to cycling for more form-fitting (aerodynamic or less wind grabbing) garments!
With air temps where they were and the wet conditions, they should have thought more about keeping the legs covered, and borrowing again from cycling and using some embrocation treatment before to help keep the legs warm
25% - 30% of heat loss is through the head - wear a tuque.
I spent many a winter in Vancouver running in wet and 0C - 5C conditions. Always ran in full tights or half-tights with knickers with a brushed inner surface to provide a bit more warmth and wicking - leg muscles are generating large amounts of heat so moisture moves well from skin to outside.
On upper body a skin tight stretchy thinner fleece material is best next to skin, and then some form of close fitting, windbreaker like vest over that that is vented well in the back, thin gloves/mittens and a tuque. In conditions like that, you are NEVER going to stay dry and the game is controlling the environment right next to your skin as best as you can. A thin micro-fleece moves great amount of moisture from inside to outside. A good amount of heat can be moderated by taking tuque on and off, and when off just stuffing it in the waist-band of your tights
