Yukon runner tells of experience

Tim Williamson, a lab technician from Newcastle has completed the worlds toughest race - the Yukon Arctic Ultra in Canada.

The 300-mile challenge through sub zero temperatures can be completed by running, cycling or skiing.

Tim opted to run - dragging his sled and all his equipment behind him.

Frostbite and hypothermia were a constant threat and he endured the pain of a stress fracture in his leg during the race.

And he ended up finishing second.

We'll be speaking to Tim in our 6pm programme.
