How to run a tournament

Phase 1: Define the event

Before registration opens, you need to answer several questions that will shape every downstream decision. Start with the basics: who is this event for? A local club competition has very different needs from a regional qualifier or an open invitation event.

Define the sport, weight categories or divisions, age groups, and skill levels you will accept. Determine whether you are following a specific governing body ruleset or using your own rules. If you are using official rules from a federation, review the rulebook carefully — it may specify required bracket formats, repechage systems, mat sizes, minimum age, weigh-in procedures, and result reporting requirements.

Set a participant cap that your venue and schedule can realistically accommodate. An oversubscribed event is harder to manage than one with lower attendance. It is better to start smaller and scale than to overcommit on the first edition.

Phase 2: Choose a venue and set a date

Venue selection is closely tied to participant count and format. The number of active mats, courts, or stations determines how many matches can run in parallel, which directly controls how long the event takes. A single-elimination bracket for 32 participants on one mat runs very differently from the same bracket on four mats.

When evaluating a venue, consider: changing room capacity, warm-up space, spectator seating, parking, and whether the venue has hosted similar events before. A venue that looks large enough on paper can feel cramped when 80 participants, their coaches, and family members are all present simultaneously.

Leave buffer time at the start and end of your booking. Setup and teardown take longer than expected. A late start ripples through the entire event schedule.

Choose a date that avoids conflicts with major regional or national events in your sport. Check other events in your area that your target participants might attend. A clash with a larger event will hit your registration numbers.

Phase 3: Registration and participant management

Set a registration deadline that gives you enough time to prepare the draw. Late entries are common, but you need a hard cutoff to finalise bracket sizes, order medals, prepare weigh-in lists, and brief officials. A deadline of five to seven days before the event is reasonable for most local events.

Collect the information you actually need: full name, club or team, date of birth (where relevant for age categories), weight category, and a contact for each participant. Do not collect information you will not use — it creates work and privacy obligations.

Have a clear policy for withdrawals, substitutions, and late registrations. A participant who withdraws after the draw is made creates byes that affect everyone in their bracket. Communicate the policy before registration opens so there are no surprises.

Communicate with participants before the event. An email three days out confirming start time, weigh-in schedule, venue address, and what to bring reduces the number of calls and messages you receive on event day.

Phase 4: Select the bracket format and plan the schedule

Format selection is one of the most consequential decisions you make. The number of matches produced by your format determines the length of the event. Before committing, calculate total match count and estimate duration. Do not rely on guesswork.

As a starting point: single elimination produces n − 1 matches. Adding repechage increases that total by 20–30% depending on the system. Round robin pools multiply matches quickly. For a 32-participant event on two mats with matches averaging 5 minutes plus 2 minutes changeover, you can run roughly 17 matches per hour. An event with 100 matches would take around 6 hours.

Account for time lost to weigh-ins, opening ceremonies, medal ceremonies, lunch breaks, and the inevitable slowdowns when competitors are not ready or officials need to resolve disputes. A safe rule of thumb is to estimate your raw match time and add 25–30% for everything else.

Build the schedule in phases: early rounds on all mats simultaneously, medal rounds on a single mat as the field narrows. Finals should not start until all semi-final and repechage matches are complete so that spectators see a proper conclusion to the event.

Phase 5: The draw

The draw determines who faces whom. For serious events, seeding ensures that the strongest competitors are placed in different parts of the bracket so they meet in the later rounds rather than eliminating each other early.

Common seeding practice: seed the top 4 or top 8 based on current ranking, recent results, or coach submissions. Place seeds at fixed positions in the bracket — first and second seed on opposite sides of the bracket so they can only meet in the final. Third and fourth seeds are separated into the two halves. The rest of the field is drawn randomly within those constraints.

For club-level events where seeding is impractical or would cause disputes, a fully random draw is acceptable. The key requirement is that the draw is transparent: done openly, ideally with representatives of the participating clubs present or with immediate publication of results.

If your bracket has byes, distribute them sensibly. Seeded participants receiving byes reduces the impact of having a non-power-of-two field.

Phase 6: Staffing and officials

An event cannot run on the organiser alone. Define your staffing needs before registration opens and secure commitments early. For a combat-sport event, you typically need: referees licensed to the appropriate level, table officials to record match results and manage the call-up procedure, a weigh-in team, scoreboard or bracket display management, and someone handling general logistics.

Brief your officials before the event day, not on the day itself. Referees should know the ruleset in use. Table staff should understand the bracket software or paper system you are using and know how to handle common edge cases: a competitor who does not appear, an injury withdrawal, a protest.

Designate one person as the single point of contact for disputes and scheduling decisions. Having multiple people with authority to make decisions is a common source of confusion on event day.

Phase 7: Event day execution

Arrive early. The most common cause of a late start is the organiser needing more setup time than expected. Tables, mat layout, weigh-in station, scoreboard, and sound system should be ready before the first participant arrives.

Run weigh-ins on a strict schedule and close them on time. Late weigh-ins delay the draw or force last-minute bracket changes. Once weigh-ins are closed, confirm final bracket positions and distribute or display the draw as quickly as possible so participants can see who they face.

Call up participants in advance of their match. Waiting for a competitor who is still warming up in another room is one of the biggest schedule killers. A clear call-up system — announcing the next two matches at once so competitors are ready — keeps the mats running consistently.

Track results in real time. As each match finishes, record the result immediately and prepare the next pairing. Do not let results pile up unchecked — errors compound quickly once a few results are entered incorrectly.

Medal ceremonies should be brief and dignified. Have medals ready before the finals begin. Announcements should be clear and consistent. Participants remember the ceremony more than most other parts of the day.

After the event

Publish results promptly. Participants and clubs want to see final standings, and the longer results take to appear, the more individual queries you receive. Aim to have results visible the same day or within 24 hours.

Document what worked and what did not while the event is fresh. The second edition of an event is almost always better than the first because organisers have concrete experience to draw from. A short debrief with your team within a week of the event is worth far more than the best pre-event plan.

Thank your officials, volunteers, and venue. These relationships are the foundation of every future event.
