What you’re in for

Both races run on the undulating trail path that circles Carsington Water near Ashbourne. The half marathon starts at the visitor centre with an out-and-back section before a full lap of the reservoir; the 10k starts from Millfields car park on the far side and covers most of one lap, finishing at the same event village. The course is flagged with trail markers and arrows, has kilometre markers and marshals, and stays open to walkers and cyclists on race day. Water is at roughly 5 km intervals. Parking is paid on exit at both car parks, and 10k runners face a 25-minute walk back to Millfields if they park there. The route is not suitable for wheelchairs or buggies.

Common questions

: The Carsington Water offers 2 distances: Half Marathon (21.1 km / 13.1 miles), 10k (6.2 miles).
: No course file for the Carsington Water yet, so there's no measured climb here. When RunThrough Trails publish one, this fills in.
: Not graded yet. A TRP grade is worked out from distance and climb measured off the course file, and there isn't one for the Carsington Water yet.
: Yes, the course is marked. Navigation skills are not required.
: We don't hold a compulsory kit list for the Carsington Water. RunThrough Trails confirm mandatory kit in their race information, usually in the final instructions.
: We don't hold published time limits for the Carsington Water. If RunThrough Trails set cut-offs, they'll be in the race information.
: We don't hold a checkpoint list for the Carsington Water. What's on the table varies a lot between races, so check the RunThrough Trails race information rather than turning up expecting food.
