There is a large tri community there based out of Laguna (where Jurgen's squad is) and I would personally take your tri bike and join in with them. The road they ride is along a highway for a large part before they turn off into the less used roads and is pretty flat. I did the Laguna race two years ago and all I can say is make sure you have the gearing to get over the hill. It is a flat course with a few tough hills towards the end. A 28 you can get over on but I personally would go a smaller gear as that is severely grunting. The descent is pretty scary to and I got overly bold at the top before I started riding my brakes on a wet road hitting a hairpin type bend and wasn't going to pull it up. I tried my best to make the corner rather than lay it down (there were hay bails), there was no run off just a concrete culvert and I ended up breaking 14 bones in my back. While waiting for the ambulance a lot of people came down there. It is a pretty cool race and I would have liked to have made the after party...
