The Bullfrog Splashdown

The Bullfrog Splashdown is a multi-distance running event held at Clement Park in Littleton, Colorado. This mid-June gathering includes a variety of timed racing formats and a communal atmosphere following the conclusion of the athletic segments.

Participants can choose from several specific race categories:

  • 10k Run (Timed): A competitive 6.2-mile distance.
  • 5K Run (Timed): A standard 3.1-mile road race.
  • Bullfrog Hot Lap: A 1.5-mile course specifically for children aged 6 to 12.
  • Bullfrog Relay: A 5.5-mile fun event designed for teams.

The event features a structured registration period beginning in early March. While the individual 5k and 10k races require a registration fee, the kids' 1.5-mile lap is offered without a registration cost for eligible age groups. The venue is located at 7306 W Bowles Ave, providing an accessible suburban setting for runners and teams to gather and compete. The day combines athletic competition with a post-race party for attendees. Visit the organization's website for the most recent information.
