I used to do my 26 miles. It was an ok commute. The only problem, we did 12. 5 hour shifts. I particularily liked commuting for nite shift. I'd leave late afternoon and return early morn.
But, with nite shifts' and 12.5 hours- I felt a need to cool it in order to get enough sleep. With a regular 8 hour shift, I'd commute every day.
Particularily, if the ride was flat. Which, mine was not.
