Alistair ran the 2017 London Marathon for Battersea Dogs Home and in memory of his friend Michael Legge's dog Jerk. And so you could see a grown man cry in public for the last ten miles. His JustGiving page is still open here.
You can listen to Alistair on his latest episode of BBC Scotland's award winning 'Breaking the News' here. He will be returning in the summer.
Alistair has just produced a new showreel with the help of the brilliant people at Double Happy Films, click here to view.
