what's the windchill?

after again showing my middle finger to my trainer, i took my show outside. yes, i rode this morning. not very long.

i put on the warmest stuff i had, and grabbed the homegrown for a ride. the Sharp outside temp gauge said 19 degrees. with 20mph winds, that's a decently ugly windchill. a windchill my face felt, a LOT. i could only bear it for 45 minutes. i wanted to ride longer, as my legs and body were not cold. but, my fingers were starting to get numb, my toes were cold, and the stinging in my cheeks told me to get home.

i'm off-roading thursday morning, and i may take the chubb challenge.
