TERRY Deary has just got back from a run when I call him.
He may be 65 this year, but he shows no signs of slowing down.
In fact, at the time of our chat, he's in training for an epic challenge to run the length of Hadrian's Wall over the course of six days.
He was being spurred on by the thought of raising as much cash as possible for the charity Integrating Children, which encourages disabled children to take part in social activities.
"I do a faster run in the morning to get my blood circulating and then a long run in the evening," he says, putting me to shame.
So does he enjoy running? "No!" is his emphatic reply.

Deary, who's also enjoyed a career as an actor, is clearly very focused on whatever he puts his mind to. The fact that he's published more than 200 books - with around 60 of them part of the successful Horrible Histories series (including one on the Welsh) - is testament to that.

The very first Horrible Histories stage adaptation took place at Cardiff's Sherman Theatre in 1999 - under the banner Mad Millennium - to coincide with an exhibition at National Museum Cardiff.
Next week, two of his tales - Ruthless Romans and Awful Egyptians - will be performed in the city once more by the Birmingham Stage Company, who are renowned for their stage versions of children's classics including The Jungle Book, Tom's Midnight Garden, Kensuke's Kingdom and many Roald Dahl stories.
His stories bring historical figures to life for both children and adults. But Deary says they are not history books.
"I don't love history, I'm a children's author," he says. "They are books about people, books …
