The Century is 100% road. It travels many of the same Carnation River Valley and Snoqualmie roads as the 50 Mile, but travels further North and West for some climbs around Upper Redmond and Duvall before returning South and East to the festival grounds.
Bring a road bike, or a touring bike for some low-gears climbing advantage!
The 50 Mile is 90% road, with a 5 mile section of packed dirt forest trail by the Snoqualmie Falls. The course tours the Carnation River Valley and upper Snoqualmie Valley, mixing farmland and forest with nice views of Mt Si and the Snoqualmie River.
Bring a road or touring bike. 26" tires with a little tread for the dirt section are great.
The 20 Mile is a 88% road scenic tour of the Snoqualmie Valley, with 2.5 miles of packed dirt trail with some gravel, on a fairly flat route winding along forests, rivers, and llama farms.
Bring a touring or commuter bike with a little tread.
