Runners looking to put their skills, endurance and grit to the test turned up bright and early Saturday morning at the Georgia International Horse Park for the Navy SEAL designed Battlefrog run and obstacle course.

The event offers a 15K course with more than 25 obstacles, including crawling through mud, running, climbing, swinging, jumping and swimming. There is also a 5K with more than 15 obstacles and a 1K or 200m dash for younger participants and families.

However, some obstacles were only unveiled the day of the event. According to the event website, the element of surprise means training must be versatile to prepare for the unexpected, just as Navy SEALS do in their course of action. The "BattleFrog" is the unofficial mascot of the Navy SEALS, representing the "adaptable, resilient nature required to thrive in this fierce environment."

The race opened with a U.S. Navy helicopter flyover, followed by the sounds of a cannon before actual Navy SEALS led the first heat.

Proceeds from the event will help the Navy SEAL Foundation, Trident House and Navy SEAL Museum.

Here are a few scenes.
