It's not easy for Tracy Lockwood making a living as a professional Muay Thai fighter in Thailand.

And it won't get any easier with a title fight this weekend.

The 31-year-old from Ashhurst has been living in Thailand for five years and has been fighting as a professional Muay thai kickboxer for three years with the Tiger Muay Thai Gym.

On Sunday she is fighting for the 69kg World Muay Thai Council title and is confident her intense training has prepared her enough to win the fight.

"The trainers here, most of them have had 200, 300, 500 fights, like that," she said. "They're from all around Thailand. World champions, Thailand champs, big legends and they're training us."

Her daily schedule keeps her in good shape, training six of seven hours a day including 300 situps and a 15km run every day.

She is fighting an Englishwomen for the title who she has fought five times previously for three wins and two losses.

In her three years as a professional, Lockwood has had 37 fights for 29 wins and six knockouts but her weight division isn't easy.

"Sixty-nine kilos is quite big in Thailand. When you're big like this, the people you're fighting take a beating."

But she still fights people of all different weights, some bigger and some smaller.

A former Palmerston North Girls' High School student, Lockwood was teaching English in Bangkok before the Tiger gym offered to support her in Phuket, helping her with food and accommodation.

"I've gone from the classroom to the gym then back to the classroom."

The fight is on Sunday which is a memorial day for the Queen of Thailand and a lot of women fight that day.

It could be her last Muay Thai fight as she is considering moving into mixed martial arts where she has had one fight, which she won.

When Lockwood lived in New Zealand she competed in taekwondo and was a national representative.

She has also fought in the Muay Thai world championships with the New Zealand team and in the past she has won the AMCO world title and was the Bangla Stadium champion.
