I posted my best guesses on the proposed route for the 2010 Amgen Tour of California, but speculation is just that speculation. I had the opportunity to speak with one of the organizers and he was kind enough to fill me in. BTW, the official announcement of the route is scheduled for October 22.
The first stage of the race will be a point-to-point course starting in Nevada City in the Sierra Foothills and finishing in downtown Sacramento. Stage 2 will start in Davis and travel to Levi Leipheimer's hometown of Santa Rosa. The course will be lengthened from last year's route to include a spin by Bodega Bay which also means that the steep Coleman Valley climb may also be on the program.
Stage 3 is San Francisco to Santa Cruz which is similar to last year's stage, but it will probably not cross over the Golden Gate Bridge.
Stage 4 is San Jose to Modesto, most likely along the same route as was used in 2009 when Thor Hushovd claimed Cervelo Test Team's first ever win.
The details of Stage 5 are a bit sketchy, though it will finish in Bakersfield. Race organizers would like to put the actual finish line at Bakersfield College which sits on top of a bluff and would allow for several challenging finishing circuits once the race reaches town.
Stage 6 appears to be the mountain-top finish at Big Bear Lake. Stage 7 will be a flat, 30-mile individual time trial in the Los Angeles Area.
The final stage, Stage 8, will be very difficult. It starts with a descent from the Woodland Hills area down Encinal Road then a climb back up Decker Canyon Road. After that, multiple circuits of a local loop which includes the Rock Store Hill, a very steep climb that ascends 1000 feet in 2 miles, will be ridden before finally finishing in Thousand Oaks, the hometown of the race's primary sponsor, Amgen.
Previously, I reported that Yosemite Valley was on the agenda. Unfortunately, the Park Superintendent decided not to allow the race to come into Yosemite, because the event offers prize money and there is a rule prohibiting races of such type in the park.
