MURWILLUMBAH-raised athlete Paul Mathews is a long way from home but continues to dominate the United States triathlon circuit with his recent win in Kansas.

Mathews, 28, competed in the Kansas 70.3 early Sunday morning, along with 1400 others, competing in a 1.9km swim, 90km bike ride and 21km run.

Mathews, who was pushed hard by fellow Australian Luke Bell, who placed third, finished in a stellar time of 3hr 49min.

The Kansas victory was Matthews' third Ironman 70.3 title, after winning the 2010 Ironman 70.3 Syracuse and 2009 Ironman 70.3 Buffalo Springs.

A week prior to his Kansas triumph, Mathews placed fourth in the Rev 3 Quassy in Middlebury, Connecticut, winning $A10,500.

Through his recent athletic success, Mathews has qualified for the Ironman World Championship 70.3 in Lake Las Vegas, Nevada, on September 11.

Despite his obvious talent, Mathews remains humble about his achievements.

“It's a good pay day and I'm excited about how I can run ‘so so' but still be so close to the lead guys,” he said.

“First two miles on the run I felt good but my calves tightened up and they were killing me.

“Anyway, I drifted back to sixth but I was hanging in close to the boys and I finally started to come good with about 3km to go and ended up in fourth.

“Rev 3 Quassy half ironman has paid off with a fourth place, in a really good field and some very good money.”
