Running GP Croft Motor Circuit November 2025

Join us on Sunday 30th November 2025 for the return of the Running GP 5k, 10k, 10mile, Half Marathon, 20mile & Marathon at Croft Motor Circuit in support of Darlington Harriers & Athletics Club!

Croft Motor Circuit has been home to many motor racing events since the 1920′s and has previously hosted the British Touring Car Championship, British Rallycross and Pickup Truck Racing race series. This is a unique opportunity to choose from a 5k, 10k, Half Marathon, 20-mile or marathon and enjoy the thrill of running a brand new course and racing your way to a new chip-timed personal best on this smooth traffic-free tarmac motor racing circuit!

Each Mile will be accurately marked out and we have plenty of helpers to keep you quite literally on track and encourage you on your way to that chequered flag finish. Included in your entry fee is a themed medal, chip-timed results, free race photos, water, and post-race goodies!

Please note that there are no dogs allowed on site.

Here at RunThrough we are always looking for like-minded people to join our community. We always value an extra pair of hands and would love for you to come along and help us! From managing stalls at the event village to handing out medals at the finish, our volunteers are a critical part of what make RunThrough events so special!

We have been extensively researching into what runners consider important, and sustainability is fast becoming the most important area. Click HERE to see what RunThrough is doing for sustainability.

T-Shirts at events have been a hot topic mainly around them not being a high enough quality to wear on a regular basis. So we have decided to tackle this by offering a RunThrough Kit Technical T-Shirt with a retail value of £22 for £12 with the addition of the event logo printed on the chest.

We can do this with our partner RT Kit as part of a strategic decision to not only raise awareness about the quality of the product but also to counteract the increasing costs.
