Jack Harris from Crosby, near Maryport, is taking to the ring to compete in the World Muay Thai Kickboxing Championships in Malaysia, which start tomorrow.
The 18-year-old, who works as an electrical and engineering apprentice at Sellafield Ltd, has won numerous UK tournaments over the past two years.
He has been hand-picked to compete against the best Muay Thai kickboxers in the world by the International Federation of Muay Thai Amateur (IFMA).
He is not phased by the possibility of going back to work a world champion.
Before leaving for Malaysia Jack was undertaking a punishing training schedule, which he had to balance with his work and social life.
Jack says everything in his job revolves around safety, something that he tries to apply to kickboxing too.
Muay Thai is a combat sport that originated in Thailand.
The rules differs slightly to modern kickboxing and it's characterised by the combined use of fists, elbows, knees, shins and feet.
