Gary Lough

Lough was reported to UK Athletics in 2017 as acting as a non-registered agent and coach. He subsequently applied for documentation, stating it was an administrative error on his part. He began working with multiple Olympic champion Mo Farah in February 2018, with Farah remarking that he appreciated Lough's strong will and attention to detail as a coach.

Born in Ballygally in County Antrim, Lough attended Loughborough University and it was there that he met fellow student-athlete Paula Radcliffe and the two became friends. Five years after the pair began dating and later married, having two children: a daughter, Isla (2007), and a son, Raphael (2010). Lough suffered a knee injury which curtailed his competitive career and instead focused on training and managing his wife's career. Radcliffe set the world record in the marathon while working with her husband. He drew public criticism for his coaching style after her fourth-place performance at the 2001 World Championships in Athletics. Radcliffe was distraught at missing a medal and Lough's trackside remonstration of her tactics was shown on television. Lough later apologised to his wife and the public for his reaction.
