"IT'S a massive challenge" - Archie Rowell is under no illusions that attempting to run the length of the Jurassic Coast, all 96 miles, in less than 36 hours is going to be physically and mentally demanding.

But the 21-year-old former Beaminster schoolboy is determined to complete the challenge in order to raise funds for a cause close to his heart: CALM - the Campaign Against Living Miserably.

Archie, who works in Dorchester, said he had been motivated to tackle the enormous task since running the London Marathon last year.

He said: "I'm the type of person that that if I'm told I can't do something I will always want to prove to myself that I can do it."

Archie, a former youth member of parliament for Dorset, has set out to raise £10,000 for CALM - a goal he admits will be a push.

He said he chose the charity after his close friend Sam Holloway took his own life last summer.

He added: "I'm from a single parent household and my mum's dad, John Morfey, took his own life when she was only young and so I've been able to see the generational impact there is, even 40 to50 years on and that still still shines through.

"CALM advocates for support for all those affected, directly and indirectly, by mental health and suicide and their values are something I really believe in".
