29.04 miles. (46.73 Km for all you non-imperialists) All told it took like 2 hours 15 minutes.
That's the ride to work and back sticking to the bike paths, except for the like 1 to 2 mile connector between them. Means I can definitely make the ride there with a bag, work 8 hours, and then make it home in the afternoon. And we have showers at work, so I can not be gross working all day.
