Arnott is part of the England team which is taking part in the much-anticipated Nitro Athletics Series in Melbourne.
The series is a three-meet team-based competition that combines strength, endurance, power and extreme energy. It is said the new format could revolutionise track and field.
Usain Bolt is headlining the series and Arnott has been training alongside the world’s fastest man.
Bolt has his own ‘All Stars’ team which will be up against England, Australia, New Zealand, China and Japan in the competition.
Each team consists of 12 men and 12 women, with their combined scores counting.
Among the unique events will be the elimination mile, where the last runner at the end of each lap will be out of the race, the mixed medley relay and the three-minute distance challenge.
Arnott is set to compete in the seeded para sprint races, where distance advantages will be given to athletes depending on their classification.
The first leg of the series takes place on Saturday night in Australia and will be shown on BBC2 at 2.45pm on Sunday.
The second and third legs, also in Melbourne, will be on Thursday, February 9 and Saturday, February 12.
Christine Ohuruogu, who has won four Olympic medals including gold in 2008, is captain of the England team.
