A television feature showing mountaineer Sir Chris Bonington’s climb of the Old Man of Hoy is due to air this evening.

The BBC said the first part of its film of last year’s ascent of the Orcadian sea stack will be shown on The One Show.

The elder statesman of climbing made the ascent of the 137m (450ft) sandstone pillar shortly after he turned 80 in 2014.

The BBC film will show the ascent made with Berghaus athlete Leo Houlding. Presenter Andy Torbet was with the pair when they repeated Bonington’s first successful climb of the stack, which he made with Rusty Baillie and Tom Patey in 1966.

The first episode of the two-parter is due to be broadcast today on BBC One at 7pm, with the second part scheduled for tomorrow evening.

This evening’s show will also feature the draw for the fifth round of the English FA Cup.

Late last year, grough interviewed the accomplished mountaineer. You can hear Sir Chris’s thoughts on life, death and his close escapes in our video.
