After taking part in the 2015 London to Amsterdam cycle ride, the gaffer went to the University of York to see how the money he raised is used in the fight against Prostate Cancer.
It was a chance for the PNE boss to go behind the scenes, see what happens in the laboratories and meet the people who work tirelessly to help find a cure for the disease.
Joined by Dave Garbett, son of Simon's late best friend Stephen Garbett, the group were shown a presentation by Professor Norman Maitland at the research facility, before heading in to the lab and trying out some of the equipment.
Simon and his team raised over £42,000 for the charity in the summer, and the gaffer was on hand to help launch the 2016 cycle.
Next year's ride will be the fourth annual football fundraiser from June 3rd to June 5th 2016, and this time there will be two starting points, one in London and a new starting point in Yorkshire, at Oakwell, home of Barnsley FC.
The 2015 ride saw 250 riders take part and together they raised more than £350,000. This time the aim is to raise half a million pound for the charity through the cycle.
Should they reach that target, the £500,000 would allow Prostate Cancer UK to add five new PhD students to strengthen their Men United squad and provide more support in tackling the disease.
Grayson was delighted to get the opportunity to see behind-the-scenes and see how the money raised can help fight Prostate Cancer.
“To ride in memory of my close friend, Stephen, and to do it with his son and some other great lads was an emotional journey. I won a medal for getting Preston to the Championship, but the medal I received for completing the challenge meant so much too.
“Together we raised £42,555 and to come to the research centre and see first hand what that money can fund is fantastic.
“It’s especially poignant to see that the amount the boys and I raised could fund a completely new area of research that could be pivotal in changing the lives of so many.”
