USAT single-event permit purchasers must also complete the USAT waiver, signed as a part of your online registration (USAT Annual members signed this waiver when they applied for annual membership). Relay Teams should collect the team race packet as a group if possible. All team members must pick up their own packets and present identification as above. You will need to submit signed USAT and Event Waivers for each member.


Chip Pick-up

You will be given your chip timing device the morning of the race near the transition area. Relay teams will receive one chip that will be transferred from member to member at your bike rack space in the transition area.


Body Marking

Is required for all participants. It is recommended that you get body marked at registration on the morning of the race; relay teams please arrive for body marking together. Please dress appropriately (shorts & t-shirt).


Water Temperature

After several warm days, Race Day water temperature was recorded at 81.3 degrees, making wetsuits unneccessary for the race. Temperatures above 78 degrees but less than 84 degrees wet suits may be worn, however participants who choose to wear a wet suit in this temperature range will not be eligible for awards.
