Coldest Day of the Year Bike Ride January 31st

CycleTO organizes a Coldest Day of the Year bike ride every year and it will take place January 31st beginning at noon.
There are few details as of yet, but I thought that you could pencil it in your calendar and, if you're new to frosty riding, take the time in advance to gear up for the experience.
Cheers,
Vanessa
