From 7pm, teams of walkers set off for the start of a 16 or eight mile trek centred on basecamp near Brayford.

The charity event for North Devon Hospice and Children’s Hospice South West is organised by both Ilfracombe Rotary clubs.

It takes walkers across a variety of terrain, testing their map reading and orienteering skills.

They will be well supported by a huge network of around 100 volunteers, with radio coverage, search and rescue teams on hand and plenty of manned checkpoints on the moor to help out as needed.

Throughout the night volunteers and marshals will keep the trekkers well supplied with directions, assistance as needed and plenty of tea, coffee and sandwiches.
