UBCraZ. I have run a 10K on a frozen lake, though, so I'm not that smart myself (It was called the Optimist Run).
I will say that the few times I've winter mountain biked with friends, it doesn't seem near as cold and it's pretty fun, plus no cars. A lot of the local road guys go straight to the off-road trails when it gets cold, stay there all winter, get back on the road in the spring.
