Cat 5's tend to go out way too hard, just hang on at the beginning and let them burn themselves out. Try to establish and keep a front-ish position early on (top 5-10) to avoid the yo-yo's and squirrely riders. Cat 5 breaks never work, someone will chase it back. Last lap, tell your legs to shut up and go hurt peoples feelings. DO NOT think about how fast you are going into a corner. Unless you are going like 30+ mph on a 90 degree corner (you won't be), your tires will hold. Stay in your drops, keep a low center of gravity, you'll be fine. Trust your equipment and go win it, we need to see a race report after!
