Paul Trincas will be working in the Olympics Stadium as an official for the track and field events.
During the 10 days of athletics, Trincas will be one of the people responsible for looking after athletes and maintaining the track and field of play to ensure that it is correctly prepared and marshalled.
"It is a voluntary role and I love athletics," he said. "To be part of such a great occasion within the main Olympic Stadium will be the experience of a lifetime."
A member of Newbury Athletics Club, Trincas has completed extensive training and assessments to become a qualified athletics official and was selected to be part of the 'Field of Play Athletics' Team' last September.
He has since been involved in a number of test events including the National Universities Athletics Championships which marked the official opening of the Olympic Stadium.
In his spare time Trincas coaches young people in sprint hurdles, his favourite athletics event in which he held records as a schoolboy
Speaking to Jack FM Swindon, Trincas said he was most excited about the atmosphere of being in the Olympic Stadium and meeting some of his heroes.
"It's not just about meeting athletes but also officials and all the people who are involved in making the games.
"Dai Green is a fellow Welshman and he's just been appointed the captain of Team GB so if I could get close to him and have a chat with him that would be even better.
"It is exciting and somewhat daunting not knowing exactly what to expect on a day to basis."
