As the winter series gears up for its 25th anniversary, officials have introduced a code of conduct.

The move comes after last year’s series, which introduced an entry cap for the first time, was criticised by many frustrated runners who couldn’t enter.

Organisers have also upped the numbers for this year’s series, which begins on November 2, to 400.

In a statement issued last week, a spokesman said: “In order to preserve the ethos of support, friendship and non-competitive rivalry, the committee has introduced a Code of Conduct. “This Code of Conduct is, obviously, voluntary but the committee hopes that all - both runners and spectators - respect and adhere to it.” The code asks for both runners and spectators to refrain from posting inappropriate comments or photos on social media sites, to avoid swearing and harassment during races, and to act with dignity and courtesy before, during and after each event.

The spokesman added: “The series was started 25 years ago in order to give all runners, regardless of ability or age, the opportunity to take part in organised – hence safe - cross-country running. “The premise behind the series is that all runners are able to experience the joy, excitement and benefits of running cross-country in a friendly, supportive and sociable environment whilst enjoying the magnificent scenery to be found in the Borders, East Lothian and North Northumberland. “The competitive element has always been – and still remains - secondary to this.” Entries for the 2014/15 series went live this week with places increased to 400.

The first race will be held at Lauder on Sunday, November 2.

Gala Harriers host their leg on November 16 in the town’s Policies, before racing moves onto Peebles where the Moorfoots stage their event on Sunday, November 30.

Chirnside Chasers will host their races on December 14 ahead of the festive break.

The series resumes on January 11 at Paxton House before moving to Dunbar on January 25 and the finale at Berwick on February 15.
