Event overview

Back for a third year is this enjoyable running festival with a strong community feel.

At this event you will have the opportunity to tackle a 5K 10K, half marathon, marathon or ultra.

Whether you're new to your chosen distance, or a veteran, the team will cheer you along your way!

The 6-hour event starts at 9am or the 4-hour event starts at 11am.

The location is pretty self-contained, making this an intimate event and having exclusive use of the main area with plenty of open space. There will be a water, aid station located at the lap point so no stress of having to carry lots of food, water or equipment.

There will be a bespoke medal for the event, which you will receive at the end of the race. Or if you choose the 'green' lucky dip option, you will choose from a selection of previous medals.

This event is part of Haughley Festival of Running.

Very friendly and well organised event. My first 10k and registration was straight forward. All officials and marshals were smiling and helpful. Special note to the music man and the enthusiastic female marshal by the car park! Did I mention free coffee and cake at the finish! Thanks and see you again. Darren M

Very Friendly and enjoyable event, Dave R

Excellent event. Really enjoyed it. Carol S

Great, friendly well marshalled and well organised trail run. Mark P

Brilliant event. My first 5K and ended up doing 10K. Loved it, the weather did help though. Loved the atmosphere and encouragement from everyone and the cake and coffee at the end was a bonus! Rebecca W

Well organised and easy going. Julia VE

A great course if you’re used to trail running. Thank you for all the organisation and friendly marshalls. Penelope F

Beautiful route, although a few little hills and 5km laps. Event info recommended road shoes- definitely trail with quite a bit of sandy/dusty track and tree roots, but very enjoyable. Polly C

Friendly relaxed atmosphere. Jane O

Nice chance to meet up with family for healthy fun. Thoroughly enjoyed it, I think I would like to try a 10k next time. We are all booked in for the one at Kings Lynn. Sara E
