Typical 4-5 race. There will be an all out sprint at the start, so don't get caught with your pants down. The sprint will quickly dissapate and settle down into a huge group that will go along fairly slowly until someone tries to go off the front, then that person will be chased down immediately. The group will bunch up and slow down again. This will go on for the whole race. Loafing, then a mad dash to chase anything down that goes off the front. So my advice is to just sit in towards the front third of group your first races just to get the feel of the race. Have fun.
