Runner's Feedback from our first event, held September 2019.....

Liked the route and atmosphere. Additionally, the course marking (very good indeed for a self-navigated course), the enthusiasm of the organisers, facilities at the start, plastic free, zero major bottlenecks on the route, and the value for money. I also felt that the decision to skip chip timing benefited the event, contributing to a more relaxed/friendly nature.

This was amazingly well organised for an inaugural race, and I really hope you run the event again next year.

Liked choice of distances, good routes, good checkpoints and friendly volunteers, nice area to run, tea and coffee and snacks included

Good value for money, well stocked checkpoints, excellent route description, great marshals, good parking, nice course, well organised.

Beautiful route, well written route descriptions, checkpoints were well stocked.

Route was virtually all countryside

The route was amazing. Very friendly.

Easy to find, good directions for all forms of travel in the (very detailed) race instructions, plenty of on-site parking, excellent route descriptions, excellent routes, plenty of checkpoints, excellent organisation and to top it all perfect weather!
