Named for the numerous seed potato operations that dot the route, this must-do loop connects the tiny towns of Churchill, Amsterdam, and Manhattan and mimics the same-named ride hosted by the Gallatin Valley Bicycle Club. Start at Lewis and Clark Park in Belgrade and cruise south out of town. After 11.7 miles, turn it up a notch by powering up a series of hills along Norris Road and Churchill Road before dropping into the hamlets of Churchill and Amsterdam.

After passing through Amsterdam, the route continues north into Manhattan where cyclists can refuel and refill their water bottles—you'll encounter another short stretch of rollers on Dyk Road. The final 15 miles of the ride trace the relatively flat and lightly traveled Dry Creek Road back to the start point in Belgrade. Post ride, park your bike on Belgrade's Main Street and grab a bite to eat at the Railway Sub Station.
