10 milers are so difficult to find in your racing calendar but are a great distance to test your training.

The route passes through the old Cattle Creep tunnel (hence the name!) and will take you around some great sections of North Milton Keynes.

This 1-lap course will serve as all important training for those of you with upcoming marathons and half marathons on the agenda. It’s also a great step up if you are looking for a challenge, or to increase your distance.
