Gosh, you icebike commuters are hardy souls! My fun/agony tolerance ratio must be set much lower. My commute is only six miles each way but I stopped when it got dark with the same thoughts JanT had - my kids still needed a mom! I was also having a lot of trouble regulating my temperature in the cold, despite shedding layers like a moulting bird - is there a trick (wearing wool or whatever) to this or do you just get used to the icy/sweaty condition (this is the first winter I've tried riding in)?

Also, I've noticed that reducing my two-way commute to a single ride on a trainer indoors has left me really groggy in the afternoon - that afternoon ride back home was a real stimulant.

Ditto - c'mon spring!
