From the Organizer
2025 marks year 21 for the Monster Kids Triathlon (ages 4-13).
The Keller Kids Triathlon is part of the Monster Triathlon weekend and a great way to get the kids involved in the sport of triathlon!
There will be three divisions for this untimed event. The age of the child on 12/31/25 determines the group they can join below:
Monster Kids Tri Leap Frogs (4-6 age group). Swim 25 yards, bike 1 mile and run 1/3 mile
Monster Kids Tri Road Runners (7-10 age group). Swim 75 yards, bike 2 miles and run 1 mile
Monster Kids Tri Gladiators (11-13 age group). Swim 125 yards, bike 3 miles then run 1 mile
The Monster Kids Tri will sell out well in advance of race day. Be sure to register early. There are no wait lists once the race sells out.
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.

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
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.
