    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

    The final race of the 2026 Winter Challenge Trail Series is here—and it’s the big one. On March 22, we take on a great 10K at Hickory Knolls Discovery Center in St. Charles, wrapping up the series with one last shot at winter trail glory.

    The course has a little bit of everything: dirt paths, crushed limestone, a few short climbs, and long stretches that test your pacing. After the 5K and 8K, this race is where it all comes together. It’s longer, it’s tougher, and yeah—your legs are probably going to feel it.

    Trail conditions? Total wildcard. Could be slick, could be muddy, could be fast. Either way, you’re earning that finish.

    Every runner gets a finisher medal and winter swag. If you’ve completed all three races, you’ll finally get to piece your medal set together and score the bonus gear for finishing the full challenge.

    Whether you're chasing a strong finish or just out to complete the series, this 10K is the perfect way to close it out. Show up, push hard, and enjoy the fact that you made it through all three.

    You can sign up 2 or 3 races from any of the race websites, however here are their specific addresses:
