Velo Bella Kona is organizing a mountain bike skills clinic this Saturday (tomorrow, 3/25/06) for the ladies. Held onsite at Fort Ord (the site of the CCCX races), this clinic will include both lectures and riding with lunch included. Clinic attendees will also get a discounted entry fee for the CCCX 4 race on Sunday. Many more details over at the Surly Gurl Clinic blog.
I think I'm a little late on this, but it looks like you can still register onsite. Thanks to the anonymous CCCX booster for the heads up on this.
