How many calories do you burn during a Hyrox race?

Hyrox is attracting a growing number of athletes curious about what the race demands of them physically. One of the most frequently asked questions is how many calories are burned during such an event.

The exact number depends on factors such as body weight, pace and fitness level, but estimates point to 500 to as many as 1,200 kilocalories for a full race. That puts Hyrox on a par with a half marathon combined with a serious strength training session in terms of energy expenditure.

The 8 kilometres of running alternating with eight functional workstations places sustained demands on both the cardiovascular system and the muscles. That combination drives calorie burn higher than in pure running events of a comparable distance.

Anyone who takes Hyrox seriously would do well to plan their nutrition around the race carefully. The question then is not only how much you burn, but also when and what you eat to maintain performance.
