Two of the world’s most fearless adventurers and scientists are to give a free public lecture at the University of Portsmouth on July 9.

Dr Jim Milledge and Dr Jim Cotter are among the most experienced endurance sportsmen in the world. Their lecture, ‘Performing at Extremes: Two hemispheres in 55 years’ is being held in the University’s St Michaels’ building from 5-6.15pm.

Dr Milledge is a respiratory physician and altitude physiologist who has pushed his body to its limits in 55 years of high altitude and extreme expeditions in the name of science.

He was brought up in Wales, where he caught the hill-walking bug on the slopes of Snowdonia. His career as a doctor with special interest in respiratory diseases allowed him time to pursue his professional hobby of high altitude medicine and physiology, including in the great ranges of the world, including Mt Everest and a scientific expedition to study the effect of altitude with Sir Edmund Hillary.

Dr Cotter is a physiologist and extreme sport endurance sportsman and the most successful competitor in the gruelling 100-hour challenge – an adventure race in which competitors run, cycle, swim, paddle and climb in New Zealand’s rugged terrain for 100 hours with barely any sleep. He and colleagues have taken part numerous times in order to study the effects on the body of extreme endurance.

The two men are being brought to Portsmouth by the University’s Professor of Human and Applied Physiology, Mike Tipton. Professor Tipton has spent 30 years examining humans’ physiological and psychological responses to adverse environments and the selection, preparation and protection of those who enter such environments.

He said: “This talk gives a unique opportunity to meet and hear from two remarkable men from opposite sides of the planet who have dedicated their lives and careers to pushing the limits of human endurance and studying the physiological implications of doing so.”
