Pre-selection is now done over 7 weeks with a session at your barracks every week.
The PT will involve 7 minute milings over arduous terrain with frequent spells of sprinting and 'beastings' lasting between 50 mins and 90 minutes.
No matter how fit you are you will always feel it- the PT is designed to hurt and test every level of peoples fitness and assess your psychological ability to overcome discomfort.
The majority of people fail pre-Selection because they give up, not because they are binned!
It is after all, PRE-Selection- the phase designed to build you up.

At the end of the seven weeks you will progress to the first Test weekend.
8 miler cross country in 64 minutes (if anyone can't do this at this stage, they deserve to fail! it is after all very easy ( I think too easy)
Throughout pre-selection before or after PT you will be given practical and theoretical navigation training with a map and compass in readiness for the hills.
21 and 23 train in different parts of the country, and yes you will have to endure some serious Wales action at some point. The marches start as a sqn with your staff watched over by a PSI (permanent staff instructor) from 22 SAS- normally a sergeant or staff sergeant on attachment.
The sqns staff and PSI's are watched over by the OC TRG WNG and his SGT Major. The OC TRG WNG and his badge look after the regiments training of all the sqns lads on selection- they do not organise your weekly visits to your sqn barracks but coordinate the regimental training weekends in the hills on Selection.

After a couple of weekends walking with your sqns, you start walking in pairs, and after that alone.
Distances get longer and the bergan weights increase.
It culminates in a long weekend called 'endurance' -
2 day marches and one night march.
Every weekend also has a bit of battle PT thrown in for good measure on the sunday morning before you head back to barracks.

After the endurance weekend you do UKSF test week, a week of seven marches (one a day) with 22 SAS and the SBS.
All selections now culminate in every special forces unit getting together for the final week.
No doubt about it it's very hard, but after getting this far the end will be in sight.
The seven days culminates in long drag- the famous 60 odd click march to be completed in a set time ( about 3km an hour).
