His former employer, gym manager Tracey Gray, said he worked at Big River Squash and Fitness Centre for several years as a personal trainer.
“He was professional, he was punctual, reliable… as normal as one person to the next,” she said.
“He never showed any extremes or extremist views or any crazy behaviour.”
Ms Gray said Tarrant passionately worked in a program that offered free training to kids in the community.
“He always seemed to embody the philosophies of the fitness industry which is that we are inclusive and we accept all shapes of sizes and all fitness abilities and we are here to help and improve and help people,” she said.
Shortly after his father passed away from cancer at the age of 49 in 2010, Tarrant left his job at the gym to travel.
He funded his adventures using money generated through Cryptocurrency Bitconnect.
Tarrant is known to have visited Europe, South-East Asia and east Asia, embarking on a road trip through Portugal, Spain and France.
Social media places him in Pakistan in October of last year and in North Korea, where he was photographed in a tour group visiting the Samjiyon Grand Monument.
