I am signed up for the Metric as well. Looking forward to it. The course does not look to bad...at least on the way back...it is mostly down hill on Folsom/Auburn. Of the whole course...I think the climb that would be the most work is Baxter Grade. Now I have done that several times this year...so I know what to expect.
Softreset...yeah hydrate tonight...and pace yourself tomorrow...it should be fun.
