Double Olympic champion Mo Farah admits Britain's "perfect" sporting summer is unlikely ever to be repeated.
The nation is still basking in the after-glow of hosting hugely successful Olympic and Paralympic Games, while Bradley Wiggins' Tour de France heroics and Andy Murray's US Open win mean 2012 will stand out as a year to remember.
Farah said: "We will never have another summer like this. We cannot do this again. It's been a perfect summer of sport.
"We have had the Olympics and Paralympics on our doorstep, but then there's also been Bradley Wiggins winning the Tour de France and Andy Murray winning a Grand Slam. Brits just don't do that."
The 29-year-old, who will run in a two-mile international guest race at the Great North City Games on the Newcastle-Gateshead Quayside today, has seen his life change immeasurably during the last few weeks, and no more so than as a result of the birth of his twin daughters, Aisha and Amani.
"Compared to winning the Olympics, starting out life with twins is completely different," said Farah.
"When I'm training, I go up in the mountains and switch off while I run. I work really hard, but having twins is equally as tough.
"I'm in control when I'm training. But the twins can wake up at any time of the day or night, they can poo at any time of the day or night as well. It's completely different, but I'm enjoying it. It's great."
