Operation FIVE ZERO is a test of endurance, physical fitness, and mental strength. The Area of Operations (AO) for Operation FIVE ZERO is the Uinta-Wasatch-Cache National Forest in Utah.


Candidates must complete the 50 +/- mile route in under 24 hours to PASS and under 19 hours to earn the GBF Dog Tag.


Candidates will meet at the Start Point at the Big Springs Park, UT (LINK). At 2000hrs, GBF Staff will give an event brief before checking candidates maps and kit. Candidates are advised to carry paper maps (waterproofed), in addition to their smartphone, for navigation.

Each candidate’s backpack must weigh a minimum of 20 lbs (without water and food). Once GBF Staff are happy with the candidate's kit, they will be released to begin the route.

The route is a mix of trails and minor roads so candidates should be able to move quickly.

Candidates will have a water replen point at the 26 mile point where they can replenish their water.

Candidates finishing in under 19 hours will receive the highly sought-after 'GBF Operation FIVE ZERO’ dog tags. The first individual to complete the event in dog tag time will earn the GBF Gold Dog Tag.

IMPORTANT. Candidates who do not arrive at the 26 mile checkpoint in under 12 hours will be withdrawn.
