I signed up when they opened registration. I've never done it, either, but I watched people doing it earlier this year when I was first starting to ride a bike and knew I had to do it. I don't have a team or anything. That's a little intimidating. I have a road bike, but it's not in very good shape right now. I can't operate the front shifter very well. Hopefully I can figure out how to make that better soon.
My longest ride so far is 59 miles on a hybrid. That took 4.5 hours, and I felt pretty chipper at the end of it. I think the riding part of this won't be too hard for me.
