A brilliant race experience - so well organised and welcoming! This was our first trail race, a challenging route at times but the organisers/ other runners made it all worthwhile! We had a great day. Really appreciated the relaxed atmosphere and genuine support of all the runners for each other’s achievements! Thank you! Harri P

Absolutely amazing, best weekend, really well looked after. Marshals checking in frequently to see how you were getting on, fabulous space for all your kit, chairs table etc. Lucy F

What a wonderful race! Music at the checkpoint, getting the super long people out and settled before unleashing shorter format peeps, pizza, and an atmosphere that supports and pushes you. The only downside is wanting to stay and chat at the aid station! Andrew G

An incredible weekend. An awesome experience, extremely well organised. The zigzag crew are very supportive, such a great weekend, I enjoyed every second. Daniel W

A fabulous event in a great area with incredible support. Samantha W

Remember this forever. Really friendly atmosphere, and a good day out. James W

Very enjoyable race. Everyone friendly and helpful. Would definitely recommend for any ability. My one ask is if you are going to take details such as age category and chip times, can you publish results at that level as I found the results too summarised. Thank you! Naomi O

1st time doing this kind of run. Was great fun. Loved it, was very friendly. Victoria W
