The word “Hyrox” does not actually stand for anything.
Held in large venues around the world throughout the year, it involves a gruelling circuit of eight strength-based exercise stations with a one-kilometre run between each.
Competitors ski, push and pull sleds, row, burpee, lunge and throw heavy medicine balls at a target in an effort to finish in the fastest time.
In the mixed doubles event, women must lift the same weights as the men – another hurdle Carole had to overcome.
She completed her first Hyrox with her son Stuart in just over 90 minutes before taking on the challenge on her own at London’s Excel arena.
