City of Lincoln Council have announced that the April 3 Lincoln 10K race has filled up all of the 5,500 available spaces this year.
The application process for the annual 10K race closed on Friday, March 25 and this is the second year the 10K has been fully booked.
Almost 90% of runners signed up via the online application form at Lincoln10k.co.uk, a 3% rise in comparison to last year, which also sold out.
Senior Sports Development Officer Keith Taylor said “To have 5,500 applicants for the race this year is staggering, we’re really proud to have generated so much interest in it.
“Over the years we’ve seen it grow and grow and I’d like to thank Lincoln residents for the support and enthusiasm they’ve shown.
“I’d also like to say good luck to all 5,500 runners taking part on Sunday — I’ll see you at the finish line!”
The race, which takes place across uphill Lincoln, has grown a lot since the first event in 1997, when only 200 runners from Lincoln signed up.
This year has seen global interest, with runners coming from as far as Peru to take part.
The average runner raises £150 for charity and local businesses such as hotels and food shops get a cash boost during the event.
The race starts on Yarborough Road, then loops around the Cathedral and uphill Lincoln before finishing in Lincoln Castle.
Due to the race, there will also be a number of road closures in the area on the date.
