Registration Link
If you would like to be placed in a wave with another individual, please note that during your registration process. Understand that the adult and youth races are different distances, hence, they will have their own separate waves. Adults will not be able to race with their children as they will be in different waves. We will make every effort to place the youth in a wave near their parent’s start time.
Race Details
• Athletes will be assigned wave start times to compete in by the race organizers. The waves will be posted on this site and will also be emailed to participants.
• Athletes must be checked in for their wave at least 45 minutes prior to their start time. Any athlete that does not show up 45 min before the start time will have their spot forfeited.
• Athletes will have volunteers to record your distances in each event. Athletes will be asked to sign their distance card after the run is completed verifying that they are in agreement with the distances calculated.
• Body marking / numbers will be assigned when athletes check in with the Head Swim Timer. Athletes will start in the pool in their assigned lane. Each athlete will have their own lane!
• Any stroke may be used in the swim and athletes may walk if their feet can touch the ground. No life jackets, floaties, paddleboards, or outside assistance is permitted.
• Athletes have 15min to transition to the bike / run area in the fieldhouse. Athletes need to be prepared to move swiftly as the bike starts promptly 15 minutes after the end of the swim.
• The bike portion of the race is on an assigned stationary bike (We will be using Keiser stationary bikes in the event). Setting your seat height and warming up is part of the transition time.
• There is no standing on the bike. First violation will result in a warning and the second violation will result in disqualification
• During the run portion of the event, full laps and ½ laps will be credited (10 laps will equate to 1 mile)
• Results will be posted periodically in the fieldhouse, emailed to participants and will also be posted here after the race: https://runsignup.com/Race/IndoorTri/Page/RaceResults

Three sports, one race — swim, bike, run in sequence, with transitions that are a discipline of their own.
Open water, open roads, and competition with yourself. Cross the finish line knowing what it took to get there.
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think. Three sports in one race means three movements to train and race day never gets monotonous.
