Answers to all of your pressing questions

Race Information

What is the field limit?

Our course can support a total field of 6,000 athletes.

Can I use my own timing chip?
No. You will be supplied a ChronoTrack “B-Tag” at packet pickup. The timing tag is attached to your race bib and should not be removed. Any other tags and chips are not compatible with the ChronoTrack system.

What do I use at gear check? Can I use my own bag?
You must use the clear plastic bag provided to you at packet pickup for your items. You will not be able to use your backpack at gear check. All items must be in the clear plastic bag – no exceptions. Please close your clear plastic bag and attach your gear check bib tag to the bag prior to checking your bag.

How do I look up my bib number at packet pickup?
We will have a bib look-up table stationed at the entry way as you walk into packet pickup. Please stop by this table to check your bib number as soon as you enter. You will type in your name and press “search.” When your name pops up please remember your bib number so that you can pick up your packet. You MUST know your bib number before walking over to any of the bib pickup tables.

Post-race party is our finish festival which includes a gourmet catered hot-breakfast buffet, do-it-yourself flower station, Michelob ULTRA beer garden (must be 21 or over) with live music and local vendors.
