What's the story?

Iain Robertson Rambles.

He likes a good yarn. I'll give you that.

No, rambles – as in walking the West Highland Way. A new two-part BBC Scotland documentary follows the River City and Small Faces star as he sets out to complete the 96-mile route from Milngavie to Fort William.

Is he a keen walker?

According to Robertson: "I've always been a rambler. There's nothing I love more than sauntering through the well-trodden paths of Scotland. I'd been wanting to give the West Highland Way another go having a couple of failed attempts in my youth."

Tell me more.

A heart-warming and humorous video diary charts his progress through the majesty of Scotland's scenery. The opening episode covers the 47-mile stretch to the halfway point at Crianlarich. Joining Robertson for the first 20 miles is actor Steven Duffy, who played his brother in Small Faces.

Upon reaching Loch Lomond, Robertson is joined by chef and restaurateur Guy Cowan and Takin' Over The Asylum writer Donna Franceschild.

There's a posh packed lunch on the bonnie banks, a dramatic dog rescue and a disastrous foray into kayaking before Robertson meets up with his River City co-star, Lesley Hart, in Crianlarich.
