A team of 10 servicemen from the Six Assault Squadron Royal Marines on board HMS Albion, stationed in Plymouth, will be attempting to set a new world record mark for speed marching at the Pembrokeshire Half Marathon in Dale on Sunday, September 27.

Speed marching holds its traditions in the Second World War when soldiers wishing to begin Commando training had to run or speed march the seven miles from Spean Bridge railway station to Achnacarry Castle inside an hour carrying 36lbs of 'fighting order'. The run is still part of Commando tests, but has evolved to involve nine miles in 90 minutes carrying 32lbs.

A team of 10 Marines will tackle the course, and their official time will be based on the eighth man to complete the course.

The world record attempt will involve 36lb of kit in line with the requirements of World War Two Commandos.

Leon Marshall, Royal Marines landing craft officer on board HMS Albion, said: "We are delighted to be making our first attempt at the world record in Pembrokeshire, a truly stunning part of the world.

"We are aware from the organisers that the course is hilly, but we will be putting everything in to setting a new world record. Our aim is to break one hour 55 minutes. We will be having a second crack at the record at the Cardiff Half Marathon in October."

David Astins, events co-ordinator for organisers Pembrokeshire Triathlon Club, said: "This is the 10th anniversary of the half marathon and a wonderful way to mark the occasion. We are honoured to host the attempt, and are delighted to welcome the Marines to Dale, and will be ecstatic if the record is broken at our event."
