Race Reviews
Ian S.
Fantastic 50km race. Great route, variety of scenery, very well marked, supportive and jolly aid station team. Fun event atmosphere.
Owen G.
The race was well attended, had excellent markings and fully stocked checkpoints at evenly spaced intervals. The course was a lovely mix of road, trails, forest, fields, riverside, towns and villages throughout the race.
Jess B.
What an absolutely amazing event! First off, the event start vibes were immaculate, I’ve never set off to music before so having that new feeling was amazing!
Claire H.
This was my first long trail run that I have done following a GPS, I was pretty nervous but didn’t need to be in the end. The route was fantastic and so scenic, it was a really enjoyable route! The atmosphere was friendly and welcoming! I had such a fab time!
