Hundreds of extra places for the Ramathon are now available.
Organisers of the returning half-marathon event, which will take runners around the magnificent grounds of Elvaston Castle and surrounding area, have been allowed to increase race capacity to 2,000 places.
The first 1,000 places for the Ramathon sold out within eight hours when they went on sale and another 630 people had also signed up on the reserve list, confirming the demand for an event of this distance in Derby.
Runners can enter the race at www.ramathon.co.uk
Entries for the Mini Ramathon family fun run are also open now on the website. And, 100 places for the Birchover Business Team challenge will be available in early February.
The Ramathon will take place on Sunday, June 8, for the first time in 18 years.
The event team is working hard to ensure that runners of all abilities have a great experience and the flat course is perfect for the first timers as well as offering fantastic potential for a personal best time for the more seasoned runners.
