Ride from Lava Hot Springs to Preston via Grace and Treasureton Pass. There are three climbs on this route - the first out of Lava is steep but short, the second to Treasureton Pass is 3-4% slow grind, and the last is a 3/4 mile grind to Preston. Reportedly there are two convenience stores in Grace that open on Sundays. There's also a water spigot in the Grace City Park.
