Ultimate limit of human endurance found

The ultimate limit of human endurance has been worked out by scientists analysing a 3,000 mile run, the Tour de France and other elite events.

They showed the cap was 2.5 times the body's resting metabolic rate, or 4,000 calories a day for an average person.

Anything higher than that was not sustainable in the long term.

The research, by Duke University, also showed pregnant women were endurance specialists, living at nearly the limit of what the human body can cope with.

The study started with the Race Across the USA in which athletes ran 3,080 miles from California to Washington DC in 140 days.

Competitors were running six marathons a week for months, and scientists were investigating the effect on their bodies.
