Mark will run the London Marathon on April 23 with his mother Carol, father Mark and brother Josh.

Speaking about his preparations, he told MailOnline: ‘What you’re going through when you run alone can be taxing on the mind.

‘The moment you go up a hill, you have moments of weakness, you start to hit a wall. Mentally pushing yourself through that is constant work on your mind, which I think is great because if you have tough times in life, you need to know how to get through them.

And long-distance training is like that, it’s hard. It’s not fun to run so many kilometers, you’re not supposed to like it.

“You are in a marathon day with the noise and the fans, but the training is not to enjoy it, but it teaches you to be disciplined.”

Mark and his family are running for Flora’s Making Healthy Switches campaign, and Mark says, ‘I’m a big believer in balance and moderation in life.
