Four Scots are among eleven challengers aiming to trek to the Magnetic North Pole and play the 'most northerly' rugby match in history who began their trek across the frozen sea ice of the Arctic on Saturday.

John Houston and Steven Turnbull, both former Scotland A and Edinburgh professionals, are joined by Andrew Walker, from Dumfries, and Fergus Davidson of Edinburgh. The expedition has been organised by veteran polar explorer Jock Wishart.

The squad flew to the starting positon after completing 6 days of Arctic training at Resolute Bay in Nunavut, Canada.

The teams led by former internationals Tim Stimpson and Ollie Phillips, slept in tent last night ahead of today's start. They face tough conditions with temperatures in the Arctic at this time of year are around minus 30 degrees Centigrade and winds adding a significant windchill.

The challenge is hoping to raise over £300,000 for Wooden Spoon, the children's charity of rugby and its work with disadvantaged children throughout the UK and Ireland.

Each of the teams has learned the vital techniques they need to trek and survive in the harsh conditions and are carrying all their kit, food and supplies in pulks which they haul behind them.

Led by Team Captains Tim Stimpson and Ollie Phillips, the teams are hoping to raise £300,000 for good causes.

In a message sent by satellite phone just before their departure Ollie Phillips said: "It's Amazing how well the guys have adapted and responded. Spirits have remained incredibly high - we're working incredibly hard as a team and it's a privilege to be out here to be honest.

"The weather looks as though it is going to be stable for us and hopefully we will get the green light."
