ARMY corporal William Maclennan is in training for a back-breaking world record attempt.

The 34-year-old, who is serving with 1 Highlanders at Catterick Garrison, is already the joint holder of the speed march world record.

But he is hoping to make the record his own when he competes in the Redcar half-marathon, on March 25.

Cpl Maclennan will do the speed march in full combat gear, carrying a 40lb rucksack.

As well as trying to break the record of 1hr 57min and 12sec, he is hoping to raise £1,000 for Cancer and Leukaemia in Childhood funds.

Anyone who would like to sponsor him can contact (01748) 834097.
