After falling out of love with the sport and, by his own admission, preferring the nightlife of a student, Murray was overweight, utterly out of contention for London 2012 and weighing up a drastic career change.
However, this week he will be confirmed on Team GB, following his second over 1500m at the recent trials and his massive personal best - which carved nearly ten seconds off his previous time - earlier this season in Hengelo.
“I am absolutely buzzing that I am going to the games,” he said.
“I definitely wouldn’t have believed it at the start of the year, but as the year has gone on, I have improved with every race, and my performances have improved.
“Then I thought ‘I can do this, I can do this’, and so to have done it is great.
“This time last year, I think everybody knows I was overweight and not running properly and doing a lot of other things with my life.
“I was just being a normal student, so my life has changed massively.
"Within the space of about five weeks, I have gone from being a nobody to going to the Olympics.”
However, he is adamant he won’t be heading to the capital on a sightseeing brief.
“Anything can happen now at the Olympics, within reason,” he added.
“I am not going in there planning to be just another guy in the heat now.
“I have run the time, so I am good enough to be there, and I am going to give it everything and get some good training in between now and then."
