"My own event, the marathon, being an outdoor endurance event, is especially vulnerable to what climate change might bring in the years to come.

But more and more, heat acclimatisation will become essential, not just desirable for all marathon runners competing in hot environments"
Mara Yamauchi, British Olympian
