WHAT’S THE MOST DANGEROUS SPORT?
This is surprisingly hard to answer, as it depends both on how the risk is measured – per
participant, say, or per event – and the availability of reliable data. But according to a 2014
analysis by Prof Sir David Spiegelhalter at Cambridge University, the UK’s leading
authority on risk, mountaineering is probably the most dangerous sport, carrying a risk of
death of around 1 per cent per climb. By comparison, running a marathon is around 1,000
times safer. RM
