About Dam Tri
SWIM: 1000 Meters (Lake)
BIKE: 21 Miles
RUN: 6 Kilometers
The Dam Tri moves into its 16th season in 2025. Voted the athlete's favorite several years during its existence, this Sprinternational distance event provides a longer distance than your typical sprint tri but doesn't expect quite as much from you as the international distance. The entire triathlon incorporates segments of the Lake Murray Dam. Starting with the 1000 meter lake swim, athletes will be comfortable with or without wetsuits as water temperature will be around 73 degrees. The swim is one large triangle starting alongside the massive spillway of the dam. Once out of the water it is a quick dash to transition and onto the 2 loop mostly flat to rolling bike course. Athletes get to cycle over the dam 4 times and experience the amazing views from atop this monumental structure. The entire run course is held on the dam with an out and back format and is unlike any other run you will experience. Don't miss this exciting event just minutes from downtown Columbia.

Course Description
Course Descriptions:
The swim is one clockwise 1000 meter triangular loop. Wetsuits will most likely be allowed as water temperatures are typically in the low to mid 70s. Depending on the wind swimmers may encounter light to moderate chop with a small current.
The bike course is two loops mostly flat to rolling terrain on smooth, fast pavement. The majority of the course is on 4 lane roads that cross the Lake Murray Dam multiple times.
The 6k run course is very unique in that the entire run is held on the Lake Murray Dam running path. With 360 degree views of Lake Murray, this run is unlike any other you will find.

SCTS rules state that once you compete in a particular race category in a SCTS race - you must remain in that same category for all future SCTS races in that calendar year. The exceptions to this rule are the Aquabike, Novice and Weight categories. You may begin the year as a Novice and then switch into another qualifying category (ie: Age Group, Clydesdale). For Weight categories (Clydesdale 220+, Master Clydesdale 220+ and Athena 165+) it allows for you to drop to Age Group if you go below the weight limit for the category. If you switch to Aquabike you can switch back to your previous category at any time without penalty.
Below is a brief description of each race category:
Open/Advanced - Category for Elite participants. These are typically the fastest people in the race and they compete on an Elite/Professional level.
Age Group - Participants competing in their age group.
Clydesdale - Category for participants who are over 220 lbs.
Master Clydesdale - Category for participants who are over 220 lbs. and are 40 or over.
Athena - Category for women over 165 lbs.
Aquabike - Category for participants doing the Swim and the Bike only. Your race ends when you cross the Bike Finish mat.
Aquathlon - Category for participants doing the Swim and the Run only.
Novice - Category for beginner participants. Participants competing as a Novice have usually done less than 3 events. No age restrictions.
NOTE: You may fit into one or more of the above categories, so whichever category you choose to compete in is completely your choice. Choose the category that you feel you would have the most fun competing in.
Relay Team Info
- Relays can comprise of a 2-person (one person does 2 legs, and one person does 1 leg) or 3-person teams (each person does 1 leg of the event). Teams can consist of any mix of genders.
- EACH Relay member MUST pick up his/her own packet.
- EACH Member MUST have their photo ID and USAT card (if applicable) to pick up their packet.
- If a member is a minor (17 or under), then a parent/guardian must show an ID to get their packet.
- If a member turns 18 by the end of the year then they are considered an adult per USAT, thus they must pick up their own packet.
- If you need to replace a relay member, you can manage this from within your registration and profile at RunSignup. Often the team captain will have to be the one to make any changes.

USAT Rules/Info
USAT Rules: Click HERE to learn the USA Triathlon Competitive Rules
USAT INFORMATION:
USAT states all participants must show a photo ID at packet pick up. You will not be given your race packet without photo ID.
All participants must pick up their own race packet. This applies to individuals and relay team members.
USA Triathlon requires that all USAT annual members must show their USAT membership card during registration. With
that said you were most likely verified to be an member or not a member DURING registration. Thus, you will not be
required to show your USAT Membership card. We suggest always bringing it with you just in case.
USAT's "Age Up" Policy:
An athlete's age for any USAT sanctioned race will be his/her age as of Dec. 31 of the current race year. The age he/she is on 12/31 will determine his/her racing age group. If an athlete is due to "age-up" into the next group, it will happen at the beginning of the year, not after the athlete's birthday. This action aligns regular U.S. age group racing with the method used by USA Triathlon for its National Rankings Program and its new Grand Prix Series.
Examples:
- John Smith is 39 and will turn 40 on November 20th. John will be considered 40 for all races in the same year (January-December) and will race in the 40-44 age group at all SCTS races that year.
- Sally Jones is 29 and will turn 30 on July 3rd. Sally will be considered 30 for all races in the same year (January-December) and will race in the 30-34 age group at all SCTS races that year.
