London Marathon runner Sid Keyte, who completed the race dressed as phone box, will have his feat immortalised after it was included in the new edition of the Guinness World Records Book.

The father of three, of Tilshead, ran the marathon to raise money for mental health charity MIND, and by finishing the race in five hours, 54 minutes, Mr Keyte can now boast he is the fastest runner dressed as a telephone box.

The record also made the cut to be part of the book and the 43-year-old is featured on page 231.

He said: “It was great to dress up as something silly and run the race for charity. Because of the costume I got a lot of donations from people on the route who were watching and didn’t know me.”

He is delighted that he has beaten his fundraising target, and has raised £6,248.20 to date.

He added: “I chose the charity because I know a number of people with mental health problems.”

Approximately 50 people were attempting the records on the day with 20 of them achieved.

Mr Keyte, who works for Systems Engineering and Assessment near Bath, was the first one to attempt this particular challenge and Guinness World Records set him the time of six hours which he managed to achieve with just six minutes to spare.

Mr Keyte has run the London Marathon three times before but this was the first time carrying the 15kg phone box and said it was a challenge.

He said when he was wondering what costume he could wear for the race he happened to be driving past a phone box.

Mr Keyte built himself a frame to fit over his body and bought four cardboard phone box panels from a theatrical suppliers.

He said: “They had to be light but also as rigid as possible. I think I got it right.”

He plans to dress up in costume again next April and will find out if he has a place after the ballot in two weeks time.
