He made the switch to the longer 70.3 distance and moved from Mudgee to Spain to train. Since then he's placed 4th in both Challenge Shepparton and Challenge Batemans Bay but the highlight was his 2nd place at Challenge Melbourne last year. It was in Spain that the training relationship with Jan Frodeno kicked off. Nick raced his first iron distance race at Roth two weeks ago and crossed the line in a spectacular time of 8:05! He credits Frodeno's training, guidance and support for this great achievement but, let's face it, he's also a pretty impressive athlete!
