The fun really begins on Saturday morning with our Run with the Horses Marathon/Half/10K/5K at 7 AM, this awesome city and trail marathon is a lifetime experience as runners, pass by wild horses that are curious as to what they are doing on the trail. Many runners get beautiful photos with wild horses up close! With a 7-hour time limit, this fun race will end just in time for you to have a nice cold beer and enjoy our DJ!

If your luck is running super high that day you will come back to Expedition Island and hear the news that your duck won the Great Duck Race! This amazing Duck Race happens at NOON on Saturday, the best part you ask, step a bit closer... YOU DON'T HAVE TO BE PRESENT TO WIN!
