Everything was outstanding including a perfect and scenic running route. Karin F

My 2nd half marathon and I thoroughly enjoyed it. Flat, fast route, friendly staff, nice scenery. Brittany H

My first half marathon event. Was nice scenery and flat. Thoroughly enjoyed the day, was very well organised. The volunteers/ marshals were very supportive. Nice goody bag at the end of the event. James J

Really lovely well run course that has a mix of road and trail. Mark W

Very well organised with lots of marshalls out on the course. Friendly atmosphere and an interesting course. Roy W

I thought this event was really well run. It had a huge number of helpful Marshall’s spread well around the course. Water stations were in good places without there being too many. Sophie W

Extremely well organised event, not sure I’ve ever been able to park so close to the start line, particularly great as the rain was really coming down at the end! Flat fast course, would recommend for beginners as well as those chasing a PB. Rachel C

The volunteer marshals were brilliant - their smiling faces and encouragement really gave me a boost when I needed it most. Sophie B

A great race for a PB as long as the weather has been kind, can get pretty muddy and slippy if there has been a lot of rain. Mix of road and trail, super flat. Local to me so one I will run again for sure. Rachael H
