Runners from Yorkshire and Lancashire will battle it out in the annual War of the Roses challenge when the Bupa Great Yorkshire Run returns to Sheffield in 2013.
The city centre 10k – now in its seventh year – will take place on Sunday, September 29.
The running battle commences when participants pledge their allegiance to either Yorkshire or Lancashire, with both counties led by celebrity captains.
The county completing the 10k course in the fastest average time wins the War of the Roses trophy.
All participants have a red or white rose printed on their running number on the day.
Lancashire was victorious in 2012, beating Yorkshire by seven seconds but Yorkshire won in the previous two years.
John Mayock, Project Director at Nova International said: “We’re very excited to have the Bupa Great Yorkshire Run return for a seventh year.
“It’s the perfect opportunity to come and show some county pride whilst running, jogging or walking 10k in this fantastic city.
“The event is suitable for everyone, from complete beginners all the way up to club runners and elite athletes.”
The route starts on Arundel Gate and heads out along Penistone Road to Hillsborough.
The Bupa Junior 2.5k and Mini 1.5k Great Yorkshire Runs take place on the same day.
