A group of runners are about to begin an epic marathon challenge that will see them tackle ten marathons in ten days.
The Brathay Trust Windermere 10in10 Marathon gets underway at 9.30am from Brathay Hall in Ambleside.
Fifteen competitors are due to take part in one of the most daunting endurance runs in the world.
Runners will pound their way over 262 miles of Windermere roads and pavements to raise money for charity.
"The runners have put their lives on hold for a year in order to get themselves into the best possible shape for this event.
"It's not only a tremendous physical challenge, due to the undulating nature of the course, but will also test their mental strength to the full.
"The 'Groundhog Day' effect of running the same course, day in day out, has seen some of the finest runners fail to complete the challenge in the past.
– Mark Bushell, Spokesman, Brathay Trust
"The runners have come from all over the UK including; London, Milton Keynes, Grimsby and Bolton, whilst the oldest competitor is 61-year-old John McCann from Morecambe."
