About the Event

This event is the closest replica to Tier 1 Special Forces aptitude in the USA.

Event Start Time: Sunday 5 Sep 2021 0830hrs

The British Special Air Service (SAS) became the first ‘Tier 1’ Special Forces unit in the World and other countries soon took notice with the USA’s 1st SFOD-D (Delta Force) being modelled on the British SAS. The Aptitude phase of United Kingdom Special Forces (UKSF) Selection, commonly called ‘Hills phase,’ is at the beginning of selection and sets the standard for recruits.

Green Beret Fitness (GBF) is recreating UKSF Aptitude Phase in September 2021 over a 5 day period. This event, codenamed Operation STIRLING, is the first of its kind in the USA.

Candidates will not be pushed, shouted at, or encouraged: we are looking for individuals who are intelligent, highly motivated, and fit who will not quit under pressure.


Candidates must complete 5 route marches over 5 days. The distances will increase, and the weight will increase.

  • Day 1: 10 +/- miles. 25 lbs. Time Limit.
  • Day 2: 11 +/- miles. 30 lbs. Time Limit.
  • Day 3: 12 +/- miles. 35 lbs. Time Limit.
  • Day 4: 15 +/- miles. 40 lbs. Time Limit.
  • Day 5 (Test Route): 25 +/- miles. 50 lbs. Time Limit and partly at night.


Operation STIRLING consists of 5 routes in 5 days and candidates must complete each route, within time, to continue to the final day. If a candidate fails a route on the first 3 days, they may be allowed to continue, at the discretion of GBF staff.

Only candidates who have passed Days 1-4 will progress to the final day.

There will be checkpoints on the routes where candidates must pass through. At the end of each route candidates will be informed if they have passed/failed. Candidates who have passed will be given the location and time for the next day’s route and are then free to go back to their accommodation. There will be no official organised events in the evening in order to allow candidates a chance to prepare and rest for the next day.

Candidates who have not passed will be informed of their time and may request feedback on their performance.

Each day will proceed with the same format until the final day: Test Route. Only candidates who have passed every previous route will be permitted to continue. Test Route will be a 24+/- mile route with 50lbs, some of it at night. At the end of the Test Route, candidates will be informed if they have passed or failed. There will be food and drink on offer for all Test Route candidates, regardless of pass/fail.

The Winner of Test Route (DRAGONS DANCE) will earn a personalised GOLD GBF Dog Tag. Everyone else finishing within the time limit will recieve a personalised GBF Dog Tag.

Note: Age and Gender will not play a part in this event. There will be one standard for all.

- Routes. GBF advises candidates to have paper maps as well as a smartphone. Maps are very personal (marking, folding, storing etc) and GBF will not provide paper mapping for the event as standard. These routes only require very basic navigation: this is a race, not a navigation test.





ROUTE 5 - Test Route

Ground in General. This map covers a wide area and should only be used to familiarise yourself with the region. This is not suitable for land navigation.

AllTrails. The AllTrails website will host the routes for Operation STIRLING. If you have a subscription, you can download the routes for use offline.

- Navigation. The navigation for Op STIRLING is not too difficult if the weather is good but GBF suggests getting to know the routes before the event.

- Dress. Candidates are reminded that this part of the country, at this time of year, can have very changeable weather. Wet weather gear is advised in case of inclement weather conditions.

- Equipment.

This list is mandatory:

This list is strongly recommended:

- Replen. There will be an opportunity for candidates to replenish water along some routes but candidates should carry enough food and water to last approximately 15 miles. There will be water at the end of all the routes.

- Rations. Candidates must have a minimum of 2 x chocolate bars (or similar) as emergency rations. It is the candidates' own decision what food they wish to take for each route.

- Water. Candidates must carry a minimum of 1.5 gallon of water but GBF advises 2 gallons. The use of hydration bladders is encouraged to enable candidates to drink water while moving.

- Medical. The routes will build up in distance and weight but candidates should arrive fully fit and without injury. A personal medical kit is required by every candidate. This med-kit must contain any life-saving medication for the individual candidates and GBF Staff must be made aware of any serious medical conditions prior to starting the event.

If any GBF staff deems a candidate is medically unfit to continue, they may be withdrawn from the event for their own safety.

- Transport. Transport will be at candidates own arrangement.
