23.4 miles mostly flat (really!). We have 1:45 before sunset (7:17PM) so you can do this at a 13.3mph average and get in before the sun goes down. Bring a blinkie light if you have any doubts.

Ride leaves promptly at 5:30PM.

Ride leader will not sweep but will not leave until everyone is accounted for.

Cue sheets will be provided.

If you really want something shorter, here's a 19.9 that is flat and fast. I'll have cue sheets for it too.
