I'm doing this 25K tomorrow at Big Basin Redwoods State Park in Boulder Creek: Course Map
3410' elevation gain. Should be a walk in the park considering that covers 15.5 miles.
But, there is this amazing forecast to consider: Boulder Creek - California Weather Forecast on Yahoo! Weather. It baffles me how heat waves always come along when I am signed up for a run.
I'm hoping for nicely shaded trails. I mean, it is a park well known for it's gigantic Redwoods.
My goal? I want to finish in four hours! There, I said it. Four hours.
