Congrats on taking the plunge!

Remember that road racing will be significantly different from what you are used to in Tris and TTs. There is a lot of strategy involved, and drafting is your best friend. My first year of racing, I didn't understand that concept - would pull the entire pack around for the whole race, and then wonder why I got beaten at the end. Don't be me

Some words of advice - be steady and hold your line in the race. Don't make any sudden moves. Remember that you can have incidental contact without going down - protect your space on the road - elbows out ! If you are on/near the front, do not take a drink, and do not stop pedalling - keep your pedals turning, even if you aren't putting any pressure on them. You need to remember that everyone behind you is actually going faster than you are.

Most importantly, HAVE FUN! Can't wait to hear more about your "first time"

You do know about no clip-ons or anything, right? Your bike has to be a standard drop bar road bike. Also, no sleeveless jerseys, and you can't have a seat bag or frame-mounted pump...
