In the event of severe weather like lightning, flooding, or hurricane force winds, we will delay the event in 20-minute increments. If the weather does not improve, we will assess the situation every 20 minutes to ensure the event can still take place in some form. Our priority is the safety of our athletes, and any decisions made during severe weather will be in their best interest.

DAY-BEFORE PACKET PICKUP DATE & TIMES

SATURDAY, Oct 4, 2025

• 13:00 – 16:00 – All races can pickup.

PACKET PICKUP RULES

• It is mandatory to pick up your race packet the day before. 
• We prefer that everyone picks up their own packet the day before the race and that teams come together during this time, we understand that this may not always be possible. Therefore, we allow one team member to pick up an entire team packet, as well as family members and friends to pick up packets for racers, as long as they have the registrant’s permission and a valid ID.
• To make the check-in process quick and easy, please show your QR code at the packet pickup. We will email this to each racer the week of the event. Each QR code is specific to your registration. If you do not have your QR code, you can check in with a photo ID. You do not need to show a USA Triathlon Membership card, even though this is a USAT sanctioned event.

Can’t Pickup Your Packet the Day Before?

If you are unable to pick up your packet the day before the race, you have one more option. You can choose to pick it up on race morning by selecting “Race Morning Packet Pickup” during registration or by adding it to your RunSignup account later. This option is available on a first-come, first-served basis. Those who choose and pay for this option will have a pre-stuffed bag with their name on it ready for them before the race. Depending on the event, this pickup may be available before boarding a ferry to the start, or it may be at the common start/finish area. The add-on is per person, so each person on a team must select this add-on during or after they registration.

All racers are required to wear a wetsuit during the swim. We suggest using a Swimrun wetsuit rather than a full-body triathlon style wetsuit because Swimrun wetsuits are lighter, more flexible, and easier to run in without overheating. However, any type of wetsuit is acceptable.

For those who do not own a wetsuit and prefer not to purchase one, we have a limited number of Ark Sports rental wetsuits available. These suits can be rented as an add-on during registration, or you can add them later by logging into your RunSignup account and editing your registration to include the rental suit.

ALREADY REGISTERED AND NEED TO ADD-ON A RENTAL WETSUIT? – CLICK HERE

If you have rented a wetsuit, you can pick it up during packet pickup. We may not have extra suits available for rent if you have not reserved one in advance, so please plan accordingly. If you rented a wetsuit and have opted for race morning packet pickup, your wetsuit will be available at that time.

After the race, please remember to remove any items from the wetsuit pockets and return it to the wetsuit tub at the finish line.

• Please be courteous on the roads and trails. Remember, all roads and trails are open, and Pace Bend Park attracts many patrons at different times of the day. When crossing, be sure to look both ways, and when running, stay to the right to allow others to pass and share the roads and trails.
• Minors who are under the age of 18 must obtain permission from the race director before signing up. They also need their parents to sign them up.
• Mandatory gear is required and may be checked at any time during the race. Participants without the mandatory gear will be disqualified.
• Teams must have a tether with them at all times, but are only required to be tethered together under certain conditions:

  • if they continuously separate during swims
  • if the race organizers announce that all teams must be tethered due to weather conditions.
• Teams must stick together at all times, and leaving a teammate behind is not allowed.
• Participants must stay on the marked course at all times. Going off course and returning to it is not allowed.
• Littering is prohibited, and participants should dispose of their trash in designated areas or with event volunteers.
• It is the responsibility of each individual participant to come to the start line fully prepared.This includes familiarizing themselves with all event information provided on the website, in emails, and in videos.

Volunteers are the backbone of the race. We could not do what we do for the athletes, without volunteers. We are always in need of volunteers that are ready and willing to help with various positions during race weekend. All registered volunteers receive a t-shirt, and meal after their shift concludes. All volunteers must register via our system and check in and out for their shift. Some volunteer positions even have stipends associated with them and groups that volunteer and identify themselves as such will be eligible for a donation.

Every water stop will be equipped with a minimum of two coolers.

• One cooler will contain regular water.
• The other cooler will be filled with Precision Hydration electrolyte-infused water. You can identify this cooler by the “PH” marking on its top.
• Additionally, most, if not all, water stops will have a bucket or container holding PH gels.

Please ensure that any trash you have is disposed of in the designated trash bag, typically tied to the handle of one of the water coolers. Leaving trash on the course or failing to use the trash bags will result in immediate disqualification and a ban from all future races.
