Jennie You can take proof of time to Runner Relations at the Expo and they will switch you into the time-appropriate corral.

Yep, as Maura said, this is easy to do at the expo. Bring a print-out with your name/time, the distance and date of the race to Runner Relations. They'll put a sticker on your bib with your new corral placement. I did this for my brother in 2011 and 2012 and it was no problem.
No prob!Have fun and happy running!
Maura is correct, but I want to reiterate something that many folks are simply confused on.
If one estimated a finish time of 2:45 or more (5:00 marathon) a proof of time is NOT required. If I were a new runner and had no idea of expected finish times, I would put 2:45 or 2:50. That will keep you out of the last corral and still not require a proof of time.
If one estimated a finish time of 2:44 or less, proof of time is required. If one fails to provide proof, then they are placed in the last corral. You can submit a proof of time before November and get adjusted pre-race, or you can carry your proof with you to the expo. There a quick trip to runner relations will get you adjusted to the proper corral.
Note that if one assumed a 2:50 time at registration and then found speed in a fall 10k then they can always re-estimate their finish times and supply proof of time later.
I hope this helps.
Here are some times that one could expect in from a 10 k
70 minute 10k = 2:35 Half
65 Minute 10k = 2:24 Half
60 Minute 10k = 2:13 Half = 4:41 Full
58 Minute 10k = 2:09 Half = 4:32 Full
55 Minute 10k = 2:02 Half = 4:18 Full
53 Minute 10k = 1:58 Half = 4:08 Full
50 Minute 10k = 1:51 Half = 3:54 Full
Thanks, all. I put a time of 2:45 for DH and myself when I registered since it wouldn't accept an empty field, so that means we're NOT automatically in the last corral then? That's a relief. Thanks!
