I probably couldn't get my 'bent ready by this weekend unless someone's willing to loan me some V-brake levers, but I can probably get my Bianci Boardwalk ready to go. Only a couple of gears work, but that's probably good enough.
Indeed, it's not a race, a very slow ride for the first eight to fifteen miles (due to the logistics of 30K+ cyclists on one road), lots of kids and families and groups and clubs, extremely slow with back-ups and jams but great fun seeing so many fellow cyclists from nowhere!
