The deep potash mine at Boulby on the North Yorkshire coast, which is operated by ICL Fertilizers, is to be the site of an unusual record attempt.

A team of marathon runners will use the mine in an attempt to run the deepest marathon on record, whilst raising funds for three charities devoted to mental health issues. The seven runners include five ICL staff and Sally Orange and Jordan Wylie, two ambassadors from the British Army Cadet Force.

Guinness World Record is to supervise the marathon, which will take place on October 10th, World Mental Health Day. The runners will complete 26 miles, 385 metres (42.2km) 1,000 metres below ground. Reflecting the hidden nature of many mental health issues, the event is entitled “Beneath the surface”.

The ICL team members comprise European agronomist Scott Garnett alongside members of the ICL mine rescue team: Simon Pollitt, Phil Welsh, Steve Riddiough and Rob Smaling. “ICL is a very proud advocate of work to reduce the social stigma of mental health,” says Mr Garnett. “We offer support and advice to all our ICL team members around the world. In the UK we have set up in-house counsellors and external counsellors to help anyone that wants to talk.”

Three charities will benefit from the attempt – the Soldiers, Sailors, Airmen and Families Association (SSAFA); Young Minds, a charity committed to improving children’s wellbeing and mental health; and Frontline Children, which focuses on helping children who are caught in the middle of conflict and war.
