Deply to Dachshund: Yes, I've done Diablo in the past and plan to do it again this fall. So far my training is on track, except I'm not yet at the proper weight. Still, I could ride Diablo tomorrow if I wanted to, provided I transported my bike to its base by car. I want to be able to ride from my little condo (at the bottom of Tunnel Road -- the Parkwoods) all the way to Diablo, up it, down (something in itself), and back home.
Are you also from the East Bay? We should go for a spin sometime. I'm johntechwriter at yahoo dot com.
