Rob Davidson set for Land's End to John O'Groats kayak test
A fundraiser is preparing to paddle 900 miles from Land's End to John O'Groats by kayak.
The route will take Rob Davidson, from Hebden Bridge, West Yorkshire, along stretches of coastline and canals.
He is taking on the challenge as his friend, Abigail Marshall, from nearby Todmorden, has breast cancer.
Mr Davidson said it would be great to see the coastline and canals "from a different angle".
"We had a silly idea and it kept running", he added.
Mr Davidson is due to start on 1 June at Land's End and finish the route 32 days later in the north of Scotland.
After paddling along the northern coast of Cornwall, Devon and Somerset, he will take to the canals of England via the Bristol Channel - not re-entering sea water until he reaches Cumbria.
From there, he will navigate the Irish Sea before going back inland at the Scottish town of Lochgilphead in Argyll and Bute.
The final push will see him travel across Scotland via the waterways between Fort William and Inverness and into the North Sea to complete the journey to John O'Groats.
Abigail Marshall, who has known Mr Davidson since school, said it was a "crazy idea" but she had "no doubt he will do it".
She has helped to set up its website and overseen logistical details for the kayak challenge.
Two breast cancer charities are set to benefit from money raised by the challenge.
