I wasn’t prepared this time, but perhaps on my next trip to Denver I will be ready to avail myself of the designated bike route that has signs posted all over the airport.
Here you can see that the bike route starts inside the terminal!
This route is not for the faint of heart. People who have done it report that riding so close to cars zipping by at 70 is nerve racking (but something they would do again). Still, I’m just happy that some facility has been made to make a distant and rather inaccessible airport more accessible.
MassBike has information about riding your bike to Logan.
