I'm a teacher, so about to be unemployed for a few months (yay--more riding time ), but thinking about bike-commuting in the fall. I've figured out the only possible route is 23 miles each way. I couldn't do that now--AND then teach all day, then get my tired a$$ home in the afternoon--but with all summer to train, it could be possible.

Does anyone do a commute of this distance on their bike? What's a source for me to read up on possible pitfalls, preparation, bike mods for commuting? TIA!
