Debertolis collapsed during event at World Games in China

Debertolis was competing in the final of the men’s middle-distance event when he collapsed. Reportedly, the temperatures in Chengdu at the time of the event were above 30 degrees.

The World Games organizers and the International Orienteering Federation (IOF), in a joint statement, said that they were “struck by this tragedy and extend their heartfelt condolences to the family and friends of the athlete and the whole orienteering community. Our thoughts are with those touched by this event.”

Orienteering is an outdoor sport in which athletes have to complete an unfamiliar designated course with the help of maps and a compass. They need to register their presence at various checkpoints, and the fastest to complete the course gets the gold medal.

The middle-distance event at the World Games in China was held around 50 kilometers outside of central Chengdu in a rural area. The middle-distance event at the World Games featured a six-kilometre course including 180 metres of ascent and 20 checkpoints.

Debertolis was one of 12 athletes who were marked as “Did Not Finish” in the official results.

He had finished fifth in the 2022 World Cup final.

The Italian currently lived in Sweden, where he was also pursuing a PhD at a university in Stockholm.

The World Games is a multi-sport event that is hosted every four years for events that are not part of the Olympics.
