My South Bay 215K permanent was just approved by RUSA.
Update 10/13: Due to road construction and repaving on Silver Creek Valley Rd (SCVR) between miles 26-30, I strongly recommend that riders use the multiuse trail that runs alongside SCVR. This multiuse trail - some may call it a sidewalk :^) - is known as the Silver Creek Trail. By all indications bikes are perfectly legit on this trail; however, you will of course need to be aware and careful of pedestrians also using this trail.
Here's the route on Bikely (click here for the more detailed map):
Bikely's elevation chart shows about 3400 ft of climbing, but I'm listing it as 4000 ft in the RUSA database until someone actually rides the whole thing and proves otherwise. I'd rather overestimate than underestimate the amount of climbing.
At any rate, it should be considerably easier than my East Bay 200K. It might not be as scenic (although parts will still be very nice), but the roads will generally be good, with especially fun descents down
*Update 10/5: I drove out to Silver Creek Valley Road today and yes, the surface of the entire length of the road has been ground away for resurfacing. Signs say that the estimated completion is July 2009. RATS!!! I'd rather not take the route over this road, particularly over the long downhill section. I thought I might need to re-route up Hassler Parkway, which is a stinker of a climb, but I may be able to use the Silver Creek Trail instead. I'll do a test ride this coming weekend and submit the change to the RUSA permanents coordinator for approval.
