Kit List

Bring your PHOTO IDENTIFICATION (ID) or a copy of your ID in order to receive your packet. A valid driver’s license or a valid passport is best. Minors are not required to show a photo ID.


Can I pick up my friend’s packet for them?

Yes! Bring a copy of their photo ID and you will be given their packet.

Are we required to pick up our packets before race day?

No, but it is strongly recommend that you do. This allows you to get ready for your race instead of waiting in a line on race day.

What time should we be there on race day?

Check-in opens at 6:00 a.m. It is recommended you get there 60 minutes before your start time to park and get ready for the race. If you didn’t get your packet before race day, you may want to give yourself even more time.

If I cannot race, can I give someone else my race number?

No. Race entries are non-transferable.

Is there is a time limit?

There is no time limit.
