Post ride report....The tires were great. There was lots of mud, but it was dried out enough not the be problematic. For the most part, the mud was more like riding on Play-Doh than being a soupy, sticky mess I probably would have been okay with my usual Tufo 40s, but running 35s on this course worked out well. There were a couple of sections that the extra tread on the rear end was probably helpful. I did spray my frame with Pam before the start, but I couldn't really tell you if it was any better than not spraying. It certainly didn't do any worse. I didn't see anyone on the course who was having significant mud issues with their bike, but there were a couple folks who were stopped and scraping mud from around their cleats. We did a lot of walking that day.
