Entries for Chippenham Half Marathon have sold out two months before race day.

More than 400 tickets for the half marathon, voted single best road race in the country, by readers of Runner’s World magazine, sold in just 30 days.

But the popularity of the race, which is sponsored by the Gazette and Herald, will not lead to the expansion of the event.

Race committee member Kevin Napier said: “It would be very easy to stuff more people into the race but that is the main complaint people have of other races around the country.

“We would never do that just to make money.”

“If nothing else it would not be safe, and it would make the event less enjoyable for the runners.”

The half marathon is the third to be run by Chippenham Harriers Running Club and takes place on Sunday, September 12.

The pleasant setting of the race, combined with the largely level course, has enabled people with a variety of running experience to take part.

“Our philosophy has always been to put on a run which we, as runners, would enjoy,” said Mr Napier.

“All the Harriers are volunteers.

“That is what distinguishes us from other events like Bath and Bristol Half Marathons. We’re not in it to make a profit.”

Proceeds of the half marathon will go to the Alzheimer’s Society and Leonard Cheshire Disability charities.
