Eider Arevalo won Colombia's first gold of the World Championships on Sunday by triumphing in the men's 20 kilometre walk. The 24-year-old continued his unbeaten run over this distance in 2017 by crossing the line, wearing his country's flag as a cape, in a national record time of one hour, 18 minutes and 53 seconds.
"I am very happy. This is great for Colombia. I thank god for this triumph," he told reporters. "It was a complicated competition but I was prepared physiologically and physically. In the last 4km I decided to make it quicker and ultimately the last kilometre was decisive."
