The British international athlete has not returned after going for a run in Perthshire

A major search has been launched to find GB international mountain runner Chris Smith, who has gone missing while on a run in Perthshire, Scotland.

According to an appeal issued by Smith’s brother-in-law Billy Milligan on social media, Smith went out to run Meall nan Aighean, Carn Mairg, Meall Garbh and Carn Gorm on October 27 at 3pm, and should have returned a couple of hours later.

“Chris is an experienced fell runner and Dad to two boys who are missing him so much,” reads the appeal.

“He went out to run Meall nan Aighean, Carn Mairg, Meall Garbh and Carn Gorm yesterday at 3pm, leaving from Invervar, and should have been back around 5pm.

“He may have become disorientated and ended up further afield.”

Thames Valley Harrier Smith has raced at multiple world and European mountain running championships, finishing eighth at the European event in 2013 and 10th at the world event in Wales in 2015.
