65 fairly leisurely miles this morning, and a beautiful day for it indeed. Set out looking for a 100km (62.2 miles) @ 17mph, ended up with 65 @ 18.5mph. Nothing but 3.5 water bottles for the ride. Average ride speed got killed when I got stuck behind a big group finishing their route, and didn't want to look like "that a-hole" by blowing by them. So I just sat about two bike lengths back of their group and slugged along at their 15-16mph for about 8 miles. If not for the rolling blockade, I would have finished the day like 19.2-19.3mph I'm sure. It was sorta relaxing, though.
As we got further and further up the street, pairs kept peeling off of the group, until the final handful of them were down to just over 13mph. You'd think all those shaved legs would make for some serious speed, but looking at the Strava Fly-bys, the group speed dropped dramatically once they hit about the 50 mile mark and the group started to shrink. They really blast down the SART in a group of 10+ riders, though.
