I solo'd the lastest addition to the Seattle Randonneurs list of Permanents today for my January R-12 ride. (The R-12 award is for completing 12 consecutive months of 200k or longer rides; no double ups in the summer to make up for bad winter conditions.)
The Three Rivers v2 200k is the flattest 200k course the club has, with only 2500' of total gain. The biggest challenge is the 55 mile stretch from Darrington, WA to Clear Lake, WA with no services.
I took over an hour off my time from the original Three Rivers Cruise 200k, and finished in 8h 29m.
