Did it last year and I just registered last night for this year.

It's a good ride. You can catch a 7am Metro North train from Grand Central that will have you in East Norwalk by 8 am or so. You NEVER have to give up your bike and Metro North waives the bike permit requirement for the day.

There are three routes, 25 miles, 75 Kilometers, and the full metric century. Each has a fair amount of elevation gain. Cue sheets contain a map on the back and you can take a sheet for as many routes as you please.
