I'll be house sitting in Berkeley over Xmas and will have my road bike, but may not have a car (as in, wifey may be using it). I want to ride Mt Diablo, a climb I've read about but have never been to.
Can I take BART to Walnut Creek or some other station and be just a warm up ride on non-crazy roads away from the best entrance to the park? I'm not sure what side of the park I should start from.
In December, will early afternoon on a weekday be an okay time to go? Or would very early on a weekend day be better? Those are my two options. I'm assuming the park is never closed to bikes.
I think it will be challenging for me, so I will spend the remaining weekends of the year doing longer climbs up here in Portland. My road bike is not set up for climbing but I just struggle along.
