I rode my GT GRADE-150 Gravel bike with Clement Xplor USH tires(I put in Slime Teflon Liners and go one flat, but I think it was a wheel issue not a thorn). Lisa rode her Canondale Adventure 4 with Schwalbe tires. I think the bigger tires were better. She got a flat (on the bike rack) the day after we quit. So... That's what we rode.
