Monster Triathlon

Rather than end the multi-sport season with a bang, these athletes end their season with a SCREAM! Monster Triathlon 2025 marks year 20 and will sell-out early with over 700 athletes!

At Monster Keller, you will enjoy the beautiful indoor pool of the Keller Natatorium for a 300 meter swim; jump on your bike for 12.8 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!
