Cedar Lake Triathlon Series #3

This event is the third race of a six-race summer series held every other Thursday night at Cedar Lake in Chester, CT. The organizers offer two race formats for individual athletes and relay teams, and relay teams are explicitly welcomed.

Distances:

  • Individual and Relay Sprint: roughly 500 yard swim, 10 mile bike, 5 km run
  • Super Sprint: roughly 200 yard swim, 5 mile bike, 1 mile run

The swim is an out-and-back lake course with buoys kept to the left. Transitions are inside a fenced perimeter with space for about ten bikes per rack. Wetsuits are encouraged when water temperature is below 80 degrees and are strongly encouraged for at least the first two races. Aqua jogging is not permitted.

Younger racers may enter the super sprint but racers must be at least 13 years old. If a child races, an accompanying adult may race free when they complete the entire course with the child.

Participants must preregister; there is no onsite registration. Race day check in is required and closes before the event. In inclement weather the organizers may change the race to a duathlon, a 5K, or cancel the event.

Course rules include helmet use on the bike, staying right unless passing, no drafting, no earbuds or personal audio devices, no crossing yellow lines, remaining inside the cones, and no animals in the park. Visit the organization's website for the most recent information.
