What what what?! Apparently Korean archery team-building exercises involve the podium-level squad hauling charcoal briquettes up a hill in some anonymous, not-particularly-salubrious part of town somewhere – and for charity, by the looks of things. In winter (temperature today around 3°C / 38°F). You see, that’s clearly what’s missing from a lot of elite sporting training programmes. Tedious, exhausting exercises where you get filthy and help other people. Wanna win? Go somewhere cold and depressing. I mean, it worked for this guy, right?
