A question for all of you ladies who have ridden both the Holstein 100 and the Tour of Napa Valley...which one would you choose?

I think I'm leaning towards the Holstein, but I have a couple of friends doing the Tour of Napa Valley. However, these two friends ride hybrids and I don't think we'd really be riding together anyway. From what I've read in the Holstein thread, it sounds like a great route. I'm concerned the Napa ride could be kind of hot.

If you had to pick one over the other, which one would it be? There is no way I could do both rides (yet ).

Oh, and I'm planning on the metric route.

Thanks in advance!!!
