Italian orienteering athlete Mattia Debertolis, aged 29, passed away on Tuesday following a collapse during competition at the World Games in Chengdu, China. The incident has cast a shadow over the 12th edition of the multisport event, which features disciplines not included in the Olympic Games and runs until August 17.
Debertolis was found unconscious during an orienteering event on August 8 while participating in the men’s middle-distance final, the first medal event of the Games. A joint statement from World Games organisers and the International Orienteering Federation (IOF) confirmed his death four days later, despite receiving immediate expert medical care at a leading Chinese medical institution. The statement did not disclose the cause of death.
The competition took place under challenging conditions, with intense heat and humidity and temperatures exceeding 30 degrees Celsius. Orienteering requires athletes to navigate an unmarked course using a map and compass, punching in at designated control points along the route in the shortest time possible. The six-kilometre course, featuring 180 metres of ascent and 20 control points, saw athletes traverse crop fields and villages in a largely rural setting. Switzerland’s Riccardo Rancan emerged as the winner, completing the course in 45 minutes and 22 seconds, and remarked to Chinese state media, “I needed to acclimatise quickly to hot and humid conditions. I think I managed quite well.”
Debertolis, listed as “Did Not Finish” alongside 11 other athletes, held a ranking of 137th in the men’s Orienteering World Rankings. A seasoned competitor since 2014, he had represented Italy in several World Championships and World Cups. Beyond his athletic career, he was pursuing a PhD at the KTH Royal Institute of Technology in Stockholm, where he resided.
In response to the tragedy, Alfio Giomi, President of the Italian Orienteering Federation (FISO), announced that the national team would wear black armbands during the World Mountain Bike Orienteering Championships, which began on Tuesday in Poland. Giomi added, “Debertolis’ family had agreed that ‘athletes will be able to participate in the competitions in Mattia’s name and memory’.”
The joint statement from World Games organisers and the IOF expressed deep sorrow, stating, “We are struck by this tragedy and extend our heartfelt condolences to the family and friends of the athlete and the whole orienteering community. Our thoughts are with those touched by this event.” Organisers have committed to providing ongoing support to Debertolis’ family and the orienteering community.
With approximately 4,000 athletes competing across 253 events, the World Games continues until August 17. This incident marks a somber moment in the event’s history, highlighting the physical demands of the sport and the risks athletes face.
