There is only one sweeper. They sweep based on a 16 min mile finish time (3:30) from the last person to cross the start line.
Therefore, you would have a cushion based on the time that you cross in relation to the time the last person crosses, unless of course you *are* the last person to cross!
I started in corral C (barely trained due to rehabbing from a stress fracture), walked most of it, finished in 3:33 and did not see a sweeper at all, including from the overpass looking back. A friend started with me in corral C and finished in 3:48.
I have heard that they will not sweep you once you make it into Epcot (mile 11-12ish) regardless of when you will finish, but that's just a rumor.
...Thanks Kat! This makes me feel better. I am running a 10K this weekend and may use it for my qualifying time at the Princess. I am shooting for Coral C now!
