Farah, who has been running more than 120 miles a week in training, also said he had had no contact with his former coach Alberto Salazar, who remains under investigation by the United States Anti-Doping Agency.
Salazar took Farah from a good athlete to a dominant one but Farah seems confident that under Lough, the husband and former coach of the women’s marathon world record holder, Paula Radcliffe, he can improve as a marathon runner.
“I’m not going to give away secrets,” Farah said. “But training for 5,000m and 10,000m is different to marathon. But I’m happy with what we’ve done – it’s exciting. I’m definitely more confident now.
“I ran 2:08 in 2014 and the aim is to improve on that. I definitely want to continue running and getting medals for my country.”
