About the Event

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.

At Monster Keller, you will enjoy the beautiful indoor pool of the Keller Natatorium for a 300 meter swim; jump on your bike for 14.3 miles, and finish strong with a 3.1 mile run. 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.
