Endurance adventurer Sean Conway plans to run 15 marathons in 15 days – in 15 national parks.
The athlete, who famously swam, cycled and ran around the coast of Britain in 2016, starts his latest challenge on June 4 in the Cairngorms National Park in Scotland.
The self-supported journey will take Sean to Loch Lomond & the Trossachs National Park the next day, then Northumberland National Park in north-east England.
The following 13 days include:
June 7: Lake District
June 8: Yorkshire Dales
June 9: North York Moors
June 10: Peak District
June 11: Norfolk Broads
June 12: South Downs
June 13: New Forest
June 14: Dartmoor
June 15: Exmoor
June 16: Brecon Beacons
June 17 Pembrokeshire
June 18: Snowdonia.
Sean, who was born in Zimbabwe and now lives in Wales, was also the the first person to cycle, swim and run the length of Great Britain, from Land's End to John o' Groats in 2015.
On Twitter, he said: "Britain has some of the best national parks in the world and I’ve decided to run a marathon in each of them consecutively to bring awareness about how incredible they are, and to show why we need to look after them.
"So, that’s 15 marathons, in 15 days, in 15 national parks."
Sean is inviting people to run with him. He stated: "Most routes involve laps so you don't need to run a full marathon, just come and have a day on the trails to spur me on." See Sean Conway for find out more.
