Runners have successfully completed the ultimate "mammoth task" tp run a marathon a day for 10 days. 

This is the tenth year of The Great Barrow Challenge, which is based in the west Suffolk village of Barrow, and is competed by runners from across the world.

They have the option to do a 5k, 10k,  half marathon, marathon or ultra-marathon which is 50kms long. 

The races started on July 26 and ended on Sunday. 

Race director Stephen Mills said: "It is the ultimate challenge that these runners could have set themselves up with. 

"I think you have to be a little bit crazy to pick up such a mammoth task."

He added that this year, five people are doing the ten ultra-marathons, and ten people doing the marathons. 

Out of the runners, there is also the first Irish woman and the first English woman to achieve the goal of completing 1,000 marathons.

This is the second year that Mr Mill's team Zig Zag Running has organised the event, after taking over from Suffolk County Council. 

Last year, they saw a great turnout with people from Norway, Spain, Italy and Australia all coming to participate in the event. 

Mr Mills added that each day will be a different route giving participants a chance to engage with the beautiful Suffolk countryside, exploring parts of Mid-Suffolk and West Suffolk. 

"It is the perfect time for these runners to push their limits," he added. 

Each person also has the chance to tailor their experience to their own goals and have the opportunity to mix-and-match distances that suit them best. 

At the end of the event, each runner gets a medal for each day they completed a run, having the opportunity in the end to stand with ten medals.
