It's brutal out there 12F/-11C. I rode on Tuesday, took yesterday off because the kids were home from school, and did my first run commute this morning. (Starting last year I try to mix up my running and biking.) For running I choose three routes from 6.7 miles four miles and two miles depending on where I get off the inbound metro. Needless to say, today I chose the two miler and even that was rough with the headwinds.
