Thunder Road GT: Slauterhouse
Approximately 30 and 60 mile routes starting in Auburn. We'll have a convenience stop around the halfway point of the long route, and the short route will likely pass through Loami if you need a snack. Expect gravel, decimated asphalt, field roads, and maybe even some old rail ballast if we're feeling spicy. Meet up at Slauterhouse Brewing afterward!
