From the Organizer

Rather than end the multi-sport season with a bang, these athletes end their season with a SCREAM! 

Monster Triathlon 2026 marks year 21 and will sell-out early with over 700 athletes! The distances are FAST for the experienced athletes and just right for the beginner.

 

The Swim has 50 meter lanes that are 9 ft wide, the bike is a two ( NEW ) or three loop course, and the run takes place on the beautiful Keller trails. The total distances are the following:

NEW SUPER SPRINT OPTION: TWO LOOP BIKE
Swim: 300 Meters
Bike: 10 Miles
Run: 5K

SPRINT OPTION: THREE LOOP BIKE
Swim: 300 Meters
Bike: 14.5 Miles

Each event is a little different at the finish line. Some have live bands, but ALL of the events are filled with energy and WONDERFUL costumes which are ENCOURAGED! This is a great race to end your triathlon season!

 

WEATHER POLICY

In the event of inclement weather, the start time of this event may be delayed by up to 1 hour. Past this time, the event course may be shortened or altered to protect the participants.

If conditions turn unsafe, the event may be cancelled. Event changes and cancellations are at the discretion of the Race Director. 

We always strive to produce a full and safe sporting event, but sometimes the weather conditions can affect those plans. 

Considerable amount goes into planning a sporting event and we do so with the best intentions. Unfortunately, no one can control the weather and race directors are not the exceptions.

Our goal is to always produce a full event as scheduled and only modify these plans due to safety concerns some of which can be caused by weather conditions. 

Thank you for your understanding of these policies and we appreciate your participation.
