Joined by fellow Inverell Mountain Bike Club members Michelle and Brent Rees, the trio travelled to Mystic Park in Bright from March 12-15 to compete.

The national event drew athletes of ages from elite to juniors. Disciplines included Downhill (DHI), Cross-Country Olympic (XCO), Cross-Country Short Course (XCC) and Cross-Country Team Relay (XCR), Pump Track and Trials.

Competing in the XCC, Miller finished first in the Master 4 Category. Up against eight other competitors, the local athlete completed 15 minutes plus three laps to take the gold medal.

Miller and Brent also competed in the CCO event. Organisers said the Olympic track was equivalent to that of an international course you'd see in Europe.

Due to illness, Brent's result wasn't what he was hoping for, while Miller finished seventh in his category.

"Killer day out there at the MTBA National Championships XCO race. I really enjoyed the course, the technical descents were really fun. The steep solid climbs really destroyed the legs but happy to come through in seventh place.

"I'm in awe of the track builders down in Victoria. Huge thanks to Matt Worth for passing me bottles," Miller wrote on his mountain bike Facebook page.

Michelle also took on the XCC in the Master 5 Category where she finished up in fourth place. The short course had a few climbs but it's main test was speed.

"Over the last two years [the championships have] been held in Bright in Victoria but the year before that it was in Armidale so they do move it around. Both years we've had quite good attendance for locals competing," she said.

Many well-known mountain bike riders, with good credentials, couldn't stack up against the Olympic course this year due to the nature of the track, Michelle said.

"It was all about endurance, speed and technical skills. It was very challenging but exactly what [organisers] needed for the national championships."
