A recent study of Spartathlon runners showed that just after the race, their blood samples – which looked similar to those of people close to death according to Dr Papadopoulou – returned to normal within days.

While there are two thresholds, aerobic and anaerobic, which dictate whether glycolytic byproducts (primarily lactate) will begin to accumulate to levels that require a decrease in exercise intensity, the aerobic system does not completely shut off when you start to rely on anaerobic energy sources.

Regular exercise: People can engage in physical activity several hours before bedtime to encourage sleep.

What that means in practical terms is a shuffling pace. The aim as an ultra-distance runner “is trying to run with minimal leg lift, essentially trying to minimise the energy cost of your run”, says Burnley.
