It so happens that today's Tour of California stage is the individual time trial (ITT) (not to be confused with indoor time trial).

The length of this ITT is 14.5 miles, which is roughly the length of my winter commute (in the winter months I drive a couple miles to the trail so it cuts a 17 mile commute to 15 miles).

The winning time for the ITT this year was 29 min, 40 sec. 30 mph average.
