A SACK-race champ has missed out on world record glory.

Stephen Wildish is now being forced to make a second attempt at his 100-metre sack race world record.

It comes after he discovered that his earlier record bid was raced in a sack 20kg too small.

In July, the 37-year-old Wroughton dad hopped over the line in a stunning 28 seconds – smashing Olympic running ace Mo Farah’s previous record of 39.91 seconds.

“Two weeks after I did it, I got a letter from Guinness,” said Stephen.

The letter contained Stephen’s worst fear. For the sack race run to count as a world record attempt, runners needed to use a 50kg sack. At just 30kg, Stephen’s sack was too small.

It meant his record was void.

Stephen said: “That letter would have been handy to have before.”

Rather than give up, graphic designer Stephen will repeat his world record attempt at the end of the month – taking on the County Ground athletics track’s 100-metre and 400-metre courses.

Asked why he plans to put himself up for the two records, Stephen joked: “I just fancy having a toilet with two world records on the wall.”

Both distances will be attempted wearing the larger 50kg sack. “It will make no difference to the actual jumping,” said a confident Stephen.

In fact, the dad-of-two is hoping that the second record bid might prove more popular than July’s attempt: “Most people thought it was a joke last time, so they might turn up this time around.”

Stephen is still challenging Olympic runner Mo Farah to come down and take him on in the sack. Long distance running star Mo previously managed to hop his way to 39.91 second 100-metre world record.

He said: “The invitation to him to come down and challenge me is still open.”

In July, Stephen was watched by wife Susan and his two children as he crossed the finish line in under 30 seconds.

Susan, 45, had secured special permission to get the couple’s two children the afternoon off school.

She said: “I had to sign the form to say why they had to come out of school. I wrote: ‘world record attempt’.”

The Wroughton mum said of life with Stephen: “There’s never a dull moment.”

Pal Jamie Stapleton, 35, has known Stephen since they were both children. “At ten he was phenomenal and he has been training for 25 years since then,” he joked.

After the race, Jamie said: “It’s a good record. It’s not by a gnat’s whisker, either. It’s by a country mile.”

Stephen will make his world record attempts at the County Ground on Friday, October 27, at 1pm.
