I live uphill about 300yds from work and I choose to ride the Trek 820. That calc's to about 1200yds a day with lunch trips. Fun and a great wakeup but not much of a workout. The Criterium Series is on the trainer for a 3xweek spin sessions. Shorter rides, less miles but much better than nothing and really hating myself for the first month of spring riding.
Up here is N Michigan (LP) we expect a milder winter. That would be nice.
