Kurt's bid for relay team on line
The 400m runner will compete for the Australian Institute of Sport (AIS) at the Beijing Olympic Test event at the Olympic Stadium, nicknamed the 'Bird's Nest', from Thursday.
Mulcahy is vying for the last spot in the 4 x 400m relay squad.
Five athletes have already been selected and the 18-year-old is in a dog-fight with Olympic silver medallist Mark Ormrod and former National sprint champion Daniel Batman to fill the vacant sixth spot.
Ormrod was a member of the 4 x 400m relay squad that included John Steffensen and Clinton Hill that won silver in spectacular fashion at Athens in 2004.
But despite the stiff opposition Mulcahy is facing he's confident he's approaching career-best form.
"I feel really fit at the moment," he said.
"Over summer I hadn't done enough hard work because of moving down to Canberra and I wasn't as fit as I could be.
"But I'm ready to go leading into World Juniors (July 8-13) and the Olympics (August).
"I'm pretty confident but you have to run your best. If I miss the team it's not the end of the world."
Mulcahy, who was a member of the 4 x 400m squad at last year's World Championships in Japan, is more focused on winning a medal at the Junior World Championships at Poland than qualifying for the Olympics.
But the former Mullumbimby rugby league player is keen to add the Olympics to a resume that already boasts a senior World Championship appearance.
"The Olympics is just a bonus at this stage," Mulcahy said.
"But I personally want to make the team so there is the pressure you place on yourself to perform."
Since completing his Higher School Certificate (HSC) at Mullumbimby High School last year, Mulcahy moved to the AIS to train under coach, West Australian Tudor Bidder.
"I like it down here so far," Mulcahy said.
"The coaching is good and the facilities are great."
