World Obstacle, institutional name Fédération Internationale de Sports d’Obstacles (FISO), is the international governing body for obstacle sports and related events. Disciplines include Ninja (similar to American Ninja Warrior) and Obstacle Course Racing (OCR). Headquartered in Lausanne, Switzerland, it sanctions world and continental level events.
The concept of an international governing body for Obstacle Racing was originally proposed by Joe DeSenna, the founder and owner of Spartan Race. This was announced in May, 2014 when world champion adventure athlete Ian Adamson accepted the job of leading the federation and sport, originally called the International Obstacle Racing Federation.
The organization filed as a Colorado non-profit sporting organization in early 2016 under the name the International Obstacle Sports Federation (IOSF). The decision was taken at the 4th Congress to establish headquarters in Lausanne, Switzerland to better represent the majority of member federations and be close to GAISF, WADA, CAS, the majority of international sporting federations and the IOC.
In February 2018, the organization filed in Switzerland as World OCR, the Fédération Internationale de Sports d’Obstacles (FISO), following the naming convention used by many international governing bodies such as FINA, FIFA, FIBA, FIS, World Sailing, World Rugby, World Rowing, World Archery,
Technology investor and media right entrepreneur Matthew Joynes was appointed the inaugural Secretary General of FISO, in 2018.
Inclusion of full medal events in the 2019 Southeast Asian Games was approved in December 2018. The SEA Games are under regulation of the Southeast Asian Games Federation (SEAGF) with supervision by the International Olympic Committee (IOC) and the Olympic Council of Asia (OCA). Six nations expressed intention to participate in the event. Four nations medaled, Philippines (10), Malaysia (4), Indonesia (3) and Laos (1)
World Obstacle signed a Memorandum of Understanding (MoU) with the International Parkour Federation (IPF) in August 2020 to unify Obstacle Sports worldwide under a governance structure similar to Aquatics (FINA), and constitution modeled on FINA and the World Baseball Softball Confederation (WBSC). The MoU expired in December 2020.
In order to provide more autonomous governance of obstacle sports worldwide, World OCR changed its name to World Obstacle in October 2020. This provided a more inclusive name for the core sports of Ninja, OCR and Adventure Racing.
World Obstacle is a member of the Alliance of Independent Recognized Members of Sports and was officially granted Observer Status by the Global Association of International Sports Federations (GAISF) Council which convened in Lausanne on 27 September 2021.
