Welcome and Hello

The Woods - Time to run

Bys Vyken Events welcomes you to the Woods, a place of myth and legend. 

Tehidy is the largest area of woodland in the west of Cornwall and it has a history stretching back

for over 1000 years.

This is a race with an air of the ethereal, don't get lost in them deep,dark woods

Its simple really, pick a duration and just keep moving.

You have the choice of Rowan (3 hours), Ash (6 hours), Beech (9 hours) and Oak (12 hours)

You will all run the same 4 mile loop and you all start at 8:00 am, with each duration

finishing on the sound of the bell.

The event is based in the top field just off from the B3301 which will be signposted

Everything is in the field, toilets, feed station, water and your kit box.

The route will be marked with triangles and there will be some marshals on course. There will also be

a roaming referee marshal who will be checking that no one is taking shortcuts.

The course is multi terrain with a tiny bit of road, but mostly grass, mud, gravel and tree roots.

Thank you to all the businesses and volunteers that support us. These events would 

never happen without you.

See you all in Tehidy on Saturday 14th September 2024
