Mountaineer, journalist and author
Moonwalker: Adventures of a Midnight Mountaineer
His debut book, "Moonwalker: Adventures of a Midnight Mountaineer" was published in 2014 and follows his adventures climbing Scotland's highest peaks, the Munros, after midnight.
The follow-up, "A Mountain Before Breakfast" which was published in 2016 features further night adventures on the Corbetts.
Alan has climbed the Munros three times, the Corbetts and all the 3000-foot peaks in England, Ireland and Wales, many during the wee, small hours.
He is currently closing in on a fourth round of Munros as well as ticking off the Grahams and Donalds.
