Steep hills and aching legs could not stop a mother on a mission to challenge the stigma of suicide.

Sarah Moore, 59 and of Weymouth, took on a mammoth 50km walking challenge along Dorset's coastline in memory of her son Michael.

Along with her friend Susan Powne, Sarah completed the Jurassic Coast 50, hiking from Lyme Regis to Exmouth in under 12 hours.

"I couldn't walk the day after. It was the most challenging thing I've ever done but I'm glad we did it," Sarah said.

Sarah added they were among only a few walkers who were aged over 50 but the younger participants offered support and motivation to help them reach the finish line.

"There were quite a few youngsters who stopped and said it was amazing we were doing it and the marshals were so nice to us. They were really pleased to see us at the end," she said.

Originally Sarah and Susan had planned to walk 100km in 24 hours but unfortunately in the week before the challenge, Susan suffered a broken toe and Sarah fell ill with an infection.

Sarah said they had been advised by doctors not to walk but the determined pair had their hearts set on stepping over the finish line.

She completed the challenge in memory of her son Michael. Michael took his own life four years ago at the age of 24 after battling mental illness for years and the tragic loss of his brother and Sarah's eldest son, Matt.

"Michael was trained to be a chef and every day my house stank of garlic. He used it in everything. During the challenge there were steep hills, woods and the views were amazing but the whole route was covered in wild garlic and you could smell it everywhere. To me it was like Michael was there with me the whole way. There were a few tears," Sarah said.

She hoped to challenge the stigma around suicide and also raised money for Young Minds, who have supported her since Michael's death.

"I'm so grateful to everyone. If we can raise awareness and stop just one person from taking their life, I will have achieved my goal," she said.

So far Sarah has raised £800 for the charity but hopes to reach her goal of £1,000.
