Before you start

A few things worth thinking through before you commit to anything:

Step-by-step

  1. Get a team together. You need a core group of volunteers: an organiser or tournament director to lead planning, referees (at least one trained referee per mat), a tournament manager to run the Smoothcomp bracket and draw on the day, a qualified first aider, and volunteers for registration, check-in, timekeeping, and pack-down.
  2. Talk to EnglandSumo early. Get in touch with EnglandSumo at info@englandsumo.com before you commit to a venue or date. We can advise on format and rules, help source referees, list the event on the EnglandSumo calendar, and promote it through our social channels and WhatsApp community. A short conversation early on saves a lot of time later.
  3. Pick a date. Check the EnglandSumo and British Sumo calendars so your event does not clash with other competitions. Consider university term dates if your audience skews student, and avoid major bank holidays and school holidays when venues and travel may be harder.
  4. Find a venue. You need a sports hall or dojo large enough for at least one dohyo (the ring, roughly 4.55 m in diameter) plus a safety run-off area around it, changing rooms, and a registration or spectator area. A matted surface is strongly recommended so falls and step-outs stay safe. Check accessibility, parking, and public transport links.
  5. Arrange insurance. EnglandSumo coaches cover includes insurance for events, but there are caveats around event size, the number of competitors, and mat provision — contact EnglandSumo to confirm your event is covered before you finalise plans. Your venue may also require proof of public liability insurance.
  6. Get referees. EnglandSumo can help source qualified sumo referees. As a minimum, plan for one trained referee per mat. Brief referees on the competition format, the rules you are using, and any special categories (for example, adapted sumo).
  7. Set up a tournament manager. The tournament manager runs the Smoothcomp event page, manages the draw, runs the bracket on the day, handles disqualifications or protests, and publishes results afterwards. They should be comfortable with the Smoothcomp platform and with the competition rules.
  8. Arrange first aid cover. A qualified first aider is required on site for the duration of the event. For larger events, consider paramedic or ambulance cover. Make sure you know the nearest A&E and have a plan for serious injuries.
  9. Handle entries and membership. Set up registration on Smoothcomp. Competitors need current EnglandSumo membership to take part. Decide on weight categories, entry caps, and whether the event is open weight or weight-banded.
  10. On the day. Brief your volunteers before doors open. Run registration and check-in, weigh-in if applicable, the competition itself, and pack-down. Publish results on Smoothcomp as soon as possible and send them to EnglandSumo so we can share them.
  11. After the event. Publish final results, gather feedback from volunteers and competitors, and debrief with your team. If you are planning the next one, get in touch with EnglandSumo early again — it gets easier each time.
