Mark was one of 250 young people representing Team GB in Sydney with athletes from over 20 countries competing in 21 Olympic sports. The British Olympic Association regards these young people as the 2012 hopefuls.
Said Mark, "Winning the individual and then the team event has got to be my best performance yet. Both results are pretty special, espically as we were shooting against people who are quite a bit older than us.
"It was great to be at the AYOF, mixing and learning from other sports, getting to know and make new friends."
Mark had some time to acclimatise to the heat and humidity in Brisbane before he flew south to the competition in the Sydney Olympic Park.
Although suffering from a chest infection, in the individuals semi final Mark dispatched the top seed Hsiu-Yu Hu from Chinese Taipei to clinch a place in the final where he faced the world junior champion, Ryan Tyack from Australia.
Nineteen-year-old Tyack had much more experience under his belt and the lead changed hands several times. However Mark held his nerve and shot a bulls-eye with his final arrow to win by one point.
