I was out there yesterday. I was in a tie-dyed St. Arnold jersey with grey long-sleeves under it. Had my speakers mounted on the bike with music playing the entire ride.
We left toward the end of the 60-mile start but only ended up doing 40 miles. It started to rain on us at the elementary school rest stop, so we said screw it and headed back toward the finish instead.
There were quite a few crashes, especially on the last 10-15 miles for us. I'm sure a lot of it had to do not just with the roads being wet but that the painted lines on the road get extremely slippery when wet. I'm sure people were changing direction on them and their bike went out from underneath them. I almost lost it a couple mile from the start because of exactly that. Going down one of the underpasses on Allen Parkway, I tried to move left around slower traffic and my rear wheel almost slid out from underneath me. Luckily I caught it, but it could have been nasty if I hadn't (I was going 25+mph at that spot).
We did notice a ton of flats, many more than typical rides and way more than what I remember from the MS150. I'm sure the cold weather (i.e. lower pressures) coupled with the crappy roads caused quite a few pinch flats.
One thing we did notice too was that the faster riders seems a lot more aggressive that other rides I'm used to. The vast majority of riders would just silently come up closely on your left without any notice and then just cut right back in front of you. Maybe we just were around a bunch of dumbfarts, I don't know. It just wasn't anywhere near as orderly as I'm used to.
Also, there were parts of the course that weren't marked all that well. We ended up going around the roundabout on Washington at least 3 or 4 times before we figured out where to turn off. I even joked to by buddy, "Hey Rusty and Audrey, there's Big Ben!" We even ended up riding the wrong way through the finish line because there wasn't anything stopping us from turning down Smith. I understand we have a map with directions, so part of it is our own fault.
