Cardiff Met's Head Athletics performance coach marked the tenth anniversary of his own best achievement, by scooping the triple crown at the same venue as his first triumph.
James Thie first finished 4th in the World Indoors over 1500m in Budapest in 2004 and returned at the end of March to bring home the triple crown from the World Masters indoor M35 Championships.
James' gold haul started with victory in the M35 3000m in a time of 8.20.84 before winning the M35 800m in 1.53.56 the following day and finally triumphing in the 1500m, after heats in both the 800m and 1500m.
The Triple Gold medallist, who is also a Cardiff Met graduate, credits the University's first class sports facilities for enabling him to train with an elite team, and said: "I was delighted to complete the triple. The chance to go back to compete was too good not to take.
"The three event challenge was something I had aimed at for a long time, but to actually achieve it was an amazing feeling. Having the World class indoor facilities of NIAC, has always given me an advantage, as has the amazing cross-country and distance running group we have currently at Cardiff Met.
"This is a real team effort and it's always nice to show people that sport is for life and that age is just a number. Now for the next aim and challenge!"
James, 35, has been a member of Britain's running team since 1998, as well as Welsh Record holder in the Indoor 1500m, 1 mile and 2000m and celebrated in Budapest with his wife and children, Bella and Elliott.
