A chance to relive the best bits form all those WW2 POW films. This obstacle is a 50m crawl under barbed wire. It being summer, there is the likelihood of stinging nettles and brambles too. (Somehow I’m not sure that the organisers are going to be considerate enough to cut them back). Reports also suggest that the ground is covered in gravel so one way or another, skin is likely to get shredded.

The only way to tackle this is to think like G.I.Joe and just crawl for your life. Anyone with military training probably won’t find this much of a problem. The rest of us are just going to have to try and work out a strategy on the move.
