Here's a link to the magazine in Spanish: Aguas Vivas (article in page 38 and following).
And this is the English translation:
It is a quiet October evening, with the warm austral spring just started. The city of Pietermaritzburg, in the state of Kwazulu-Natal (South Africa), invites you to walk its extensive parks filled with the bright violet of jacaranda flowers. Children play, couples talk in the shade of a palm tree, a man with briefcase loosens his tie while walking slowly back home and two elderly men in a bank see time going by without major concern... and in the middle of this bucolic scene, two guys pass running at full speed with a K2 on shoulders. No one bats an eye. But we, foreigners, tend to stay staring them with incredulity and then think that the problem is that they are late to store the kayak at the hangar in Camps Drift, Natal Canoe Club headquarters, just a few hundred meters away. "No, they are training for Dusi," says one of the locals.
