A new Guinness World Record has been set by Colliers International’s Head of City Offices, Simon Crotty, who ran from John O’Groats to Lands’ End in 5 ½ days for children’s Alzheimer’s charity, Niemann-Pick as part of a 12 person relay team.

Crotty and his teammates kept a 12km/hr pace and cover two-thirds of a marathon every day. The team covered 1,500km (923 miles) an equivalent distance to running around the M25 eight times.

All runners set off from the tip of Scotland (John O’Groats) on Tuesday 28 April and completed a non-stop run reaching the boot of the UK (Lands’ End) on Sunday 03 May at 6:00pm.

Colliers Simon Crotty said “I am really proud to be part of such a great team that has set a Guinness World Record for such a great cause. What’s phenomenal is that we aimed to complete the trek in six days and we actually beat our own target by half a day. We were also able to beat our own target of £50,000 by 50 per cent and we are now targeting £100,000.

“It was mentally and physically exhausting. We started the journey just with hail then snow coming down, which is rare in John O’Groats. We survived on limited sleep – a total of eight hours across four days towards the end - and battled through cold and windy weather across steep terrain and forgotten country roads, but the positivity of the team kept us all going. A few times we backtracked due to our trusty SatNav malfunctioning.

“However, we knew we were helping a truly worthwhile and overlooked cause, which helped us get through the challenge. We aimed to raise enough money for two full time researchers for two years but hopefully will funding for three researchers.”

Niemann-Pick C is a relatively unknown disease, which affects approximately 100 children in the UK each year and is a terminal neurodegenerative disease.

The team received support from sports personalities such as Lord Coe, Paula Radcliffe, Tim Henman and TV Presenter Clare Balding.
