Glyn Knighton from Edge Diamond Stone Division, a national supplier of diamond tools for stone working, Anna Gibiino, Natural Stone Specialist's Advertising Consultant, and a friend, Lisa Shuttlewood, all successfully completed the 10km run in Derbyshire on 1 April to raise more than £1,000 for children's charity Fairplay – and that's no joke!

They all completed the run in about an hour and want to thank everyone from the industry who sponsored them. Glyn says: "It was a great but tiring day and all for a great cause. A big thank you to everyone who has sponsored us for their generosity."
