But the Wollongong triathlete says she is most content when her day is filled with training.

"Most days I'll get up and do some of my own gym and strength work at home, then at 8am I'll do a moderate run, then at 10.30am it's swimming at the uni pool, then in the afternoon it's either a bike ride or a harder run session," she says.

"Tomorrow I'm going for a 4½-hour bike ride."

And any rest days, like Sunday maybe?

"Most Sundays we have a 90-minute run and then it's the rest of the day off," is her reply.

Musgrove says she has always been competitive at sport (and can easily get up at 4am) since her parents introduced her to swimming at a young age.

Musgrove's parents David and Sally have always been keen swimmers and regularly drove to the Picton pool from their Southern Highlands home.

She enjoyed playing different sports as a youngster, including netball, tennis and hockey.

"I think it builds up the competitiveness in you to win and it also helps you learn to lose."

At 16, Musgrove began running competitively, joining Kembla Joggers and winning the 2011 national under-20 cross-country championship.

Under the wing of Triathlon Australia National High Performance coach Jamie Turner since he spotted her at the 2010 Australia Day Aquathon in Wollongong, Musgrove has propelled herself on to the list of Australia's elite athletes and is on track for the 2016 Olympic Games.

She is off with Turner's squad next month to spend five months competing in races across Europe.

She will be turning 21 during her time away, but the intense triathlon training won't prevent her from celebrating the occasion.

"I told everyone I'm having a big party," she says with a laugh.

"When we're overseas we can go to the local bars, but no-one goes over the top."

Sticking to a close diet isn't necessary for Musgrove and the team has a dietitian who regularly monitors where they are at.

"I've worked out what's best for me," Musgrove says.

"With the amount of training we do we have to fuel our bodies well. In the squad I'm in, based in Wollongong, there are five girls under 23 and we pretty much live together.

"After rides we'll have a coffee and relax and talk about everything but triathlons."

So what motivates Musgrove, who won the ITU Triathlon Oceania Cup in March, to keep up the hectic schedule?

"The thought of crossing the line first is enough to make me train harder," she says without a second's thought.

"Jamie says you have to be desperate - it's about who wants it more."
