It's not a crit: it's a short circuit race. (There are FLAT road races, and there are HILLY crits: being flat doesn't mean it's a crit.) It'll either be a break or an absurdly huge field sprint. If you're a sprinter, you're likely going to have to eat some wind in the final 60sec to stay near the front. It'll be 10 wide, 5 deep full on sprint, and it'll be messy. (Or it'll be a break...)
