For the 14th year, our Iron Eagle Paddle & Run fundraiser is set for Saturday, August 8,2026 at Eagle Creek Park!

Solo and 2 or 3-person teams are all welcome! 3-person teams are not eligible for prizes

Please join us for a trail run through one of the nation's largest city parks while catching a glimpse of the park's wonderful scenery. Competitors have the option to bring their own kayak, canoe, or stand-up paddle board, or rent a boat in advance through Eagle Creek Outfitters. All participants bringing their own water craft are required to bring a PFD (personal flotation device), otherwise known as a life jacket.

The race includes the following segments:

• 2.6 mile trail run - from the beach to the marina

The course is set up similar to a triathlon with a transition area where you can stage your gear for each leg.
