41st Seahorse Challenge

The Scene

Kalamazoo County’s, Coldbrook County Park is the scene for this year’s 40th Seahorse Challenge Triathlon, which has been the state’s big season opener to kick off another great year of multi-sport.

Plenty of lodging opportunities between Battle Creek and Kalamazoo, as well as both modern and rustic camping available at the park. Sleep in, wake up and be 800m from the transition area. The swim is in a small clear lake with two loops for the Olympic distance athletes. The transition area, finish line and post race festivities are all located in the back of the park, closed to traffic.

The bike course is a great all right turn affair with one short climb and again two loops for the Olympic distance. The run is entirely enclosed inside the park with a half cross country, half pavement course. A great course that will keep you motivated and pushing as you can hear the finish line from almost every spot on the course. A few short uphill and downhill sections as well.

Support Crews


This is a Kalamazoo County Park. You must either have an annual Kalamazoo County Park pass or purchase a daily pass for $5. This goes straight to the park to help maintain the nice facilities at the park. This $5 only allows you to enter for the day. If you come to check-in on Saturday, you will need to pay the $5 again Sunday for the event.

Athletes Responsibility

Due to an increasing amount of athletes entering events that may not be properly trained, we are asking each athlete to be responsible and honest with his/her ability to complete the distance they are registering for. Due to safety concerns for everyone involved, including you the athlete, but also support crew volunteers and officials like police, sheriff, fire department, EMS, etc. we must implement course cut off times at 4 hrs. Raffle and awards start at 3 hrs and 30 minutes in Olympic distance events and 99% of all athletes are finished by that time. So, you must register for an event you can finish under the 4 hour time limit. Being a responsible athlete means if you cannot complete the Olympic distance comfortably under that time we recommend you participate in the sprint event. We encourage you to train for the goal to reach that Olympic distance under the 4 hour time limit. If you do not have a clear idea as to how to achieve that goal we are here to help, please let us know.

An athlete will be informed he/she has reached the 4 hr. cut off, at which time the athlete will acknowledge he/she understands completely and he/she will be brought in off the course by the course coordinator. If the athlete refuses this he/she will be informed that there will not be any support left on the course from that point and he/she must acknowledge this and understand he/she is continuing under those circumstances at which time the athlete will remove the timing chip/strap and give to the course coordinator.  

Again an athlete must take the responsibility on as an athlete understanding his/her ability at the time of the event. Knowing that support crew volunteers, as well as other personnel out on courses, must be kept in safe conditions as well.
