If you are seeking recognition as an international association, club, league or similar organization, please complete and return the Affiliation Request Form. Please note that affiliated organizations cannot operate only in one country (it must be a global organization with international members) and have no voting rights at the general assembly.

OSF National Federation Membership

If you are seeking recognition as a national governing body (National Member Federation) for an Obstacle Sport or related discipline, instructions are available in the Joining Kit and Membership Criteria documents. You must complete and return the National Federation Membership Application to be considered for affiliation.

National Member Federations (NFs) wishing to become a member of the International Obstacle Sports Federation (OSF), the world governing body for Obstacle Sports, Obstacle Course Racing and related disciplines, need to meet the following requirements. These are based on the OSF Constitution and By-Laws.

  1. Name of the NF
  2. List of elected officials
  3. Mailing address
  4. Contact name
  5. Contact phone number

The NF constitutions must include clauses that:

  • refer all unresolved disputes between the NF and OSF to the Court of Arbitration for Sport (CAS); and
  • the NF has Anti-Doping Rules that comply with the WADA Code and OSF Anti-Doping Rules.

The OSF will assist NFs with compliance and governance structure.

Governing Body Status

The NF must be recognized as the governing body for the sport in their country or be working toward recognition.  The applicable National Olympic Committee (NOC) and/or National Government Sports Agency (NGSA) must confirm this status. NFs working toward recognition may be granted interim affiliation status provided they are in actively seeking approval as their recognized national governing body for Obstacle Course Racing or a related sport.
