Army athlete Tom Evans took the ultrarunning world by storm last year following his sensational podium place in the gruelling Marathon des Sables.
This season he's using the best sports science has to offer in his quest to become the best in the business.
Tom completed his debut season on the circuit finishing third in the world rankings.
Following his stunning start to his ultrarunning career, he's aware he no longer has the element of surprise but is confident he can improve this season.
In his quest for further success, he's been training in the heat chamber at one of the leading sport science facilities in the country, the Sport and Health Services Department at St Mary's University in Twickenham.
He's hoping this cutting-edge science will give him a competitive edge over his rivals.
"I'm absolutely over the moon to have these opportunities in these facilities. To be able to find out more about my body I can learn and develop myself and hopefully improve as an athlete."
Once the season gets underway Tom will trade the artificial temperatures in Twickenham for the real thing in Costa Rica.
As well as taking part in individual events, the Welsh Guards officer will make his Great Britain debut this year at the Trail World Championships in Spain.
