I've ridden and run the trails at the whitewater center a good number of times and they're really fun. An Xterra race would be a nice change of pace from hitting the pavement for 50 miles.
If you haven't been there already it's a fun place to take the family and very reasonably priced for an entire afternoon of rafting/kayaking/wall climbing/zip lining.
Are the MTB trails here more like bridal trails or more like single track trails? I like riding off road, but i don't like stuff that is really technical, I'm trying to figure out if I would be ok with this. Cause it looks like an awesomely fun race!
