Everything you need to know before stepping onto the mat for the first time, from registration and weight classes to managing nerves and knowing what to expect.
Your first BJJ competition is one of the most memorable steps you will take in the sport. Competing puts your training under real pressure, reveals gaps you cannot find in the gym, and builds the kind of confidence that carries into every session afterwards. Most practitioners find that one competition is worth months of regular training for accelerating their development.
This guide covers the entire process from finding and registering for an event, through to standing in the warm-up area ready for your first match. It draws on commonly accepted practices across IBJJF-sanctioned events as well as the broader Thai competition scene. Confirm specific rules and schedules with your event organisers and coach, as they vary between promotions.
Not all competitions suit first-timers equally. Local in-house events run by individual gyms are a low-pressure starting point: the atmosphere is friendly, the judges are usually club instructors, and brackets are kept small. Regional open tournaments attract a wider range of competitors and are structured more formally, often following IBJJF or similar rule sets.
In Thailand, events are held throughout the year in Bangkok, Chiang Mai, Phuket, and Pattaya. Some promotions run dedicated beginners or white belt divisions with modified rulesets, which can make your first experience far more manageable. Ask your coach or check the CNX BJJ competitions page for upcoming events in your area.
Key things to confirm before registering:
Most competitions require online pre-registration, often closing one to two weeks before the event. You will need to select your weight class, belt level, and division (gi, no-gi, or absolute). Some promotions charge a separate entry fee per division, so factor that into your planning.
IBJJF registration requires a valid IBJJF membership for the competitor and, for affiliated events, confirmation that your gym is registered. Local Thai promotions are usually more flexible and allow walk-in or late registration, though spaces in smaller divisions fill quickly. Confirm the registration process directly with the event organisers, as requirements differ widely.
Entry fees for local Thai events typically range from a few hundred baht for in-house competitions to several thousand baht for larger open tournaments. IBJJF events carry additional membership costs. Confirm current fees with the event as these figures change frequently.
IBJJF weight classes for adult males and females are among the most widely adopted standards in BJJ. The table below shows the standard IBJJF adult male divisions as a reference. Many Thai promotions follow similar brackets but may consolidate lighter divisions at white belt to ensure enough competitors per bracket.
| Division Name | Weight Limit (kg) | Notes |
|---|---|---|
| Rooster | 57.5 kg | No minimum |
| Light Feather | 64.0 kg | |
| Feather | 70.0 kg | |
| Light | 76.0 kg | |
| Middle | 82.3 kg | |
| Medium Heavy | 88.3 kg | |
| Heavy | 94.3 kg | |
| Super Heavy | 100.5 kg | |
| Ultra Heavy | Over 100.5 kg | No upper limit |
Weigh in at your natural walking weight for several mornings before the registration deadline. This gives you a reliable baseline. Enter the division that reflects your everyday weight. Extreme weight cutting is not advisable for your first competition: it impairs performance, increases injury risk, and adds stress to an already demanding day. For authoritative division rules, refer to the IBJJF rules guide.
Being organised the night before eliminates a significant source of pre-competition anxiety. Pack your bag well in advance and do a final check on the morning of the event.
Competition essentials:
Health and recovery items:
Thailand's heat means sweat volume is high even before you step on the mat. Staying on top of hydration throughout the day is more important here than at events in temperate climates.
Arrive 60 to 90 minutes before your scheduled division. Venues often run early or late, and the check-in queue can be longer than expected. The typical sequence of events for a first competitor looks like this:
Nerves before a competition are not a sign of weakness. They are a natural physiological response to perceived challenge and, at the right level, they sharpen focus and increase physical output. The goal is not to eliminate them but to channel them productively.
Several strategies help most competitors:
Talk to your coach honestly about how you are feeling in the days before the event. A good coach will adjust your preparation accordingly and help you arrive in the best possible mental state.
Not knowing the rules before you compete is a common and avoidable mistake. At white belt under IBJJF rules, several submissions are prohibited, including heel hooks, knee reaping, and certain spinal locks. Applying a prohibited technique results in disqualification, even if it was accidental.
Study the ruleset for your specific event before you compete. The CNX BJJ IBJJF rules guide covers the key points for white belt competitors. If your event uses a different ruleset, ask the organisers for the relevant document and review it with your coach. Also familiarise yourself with how points are scored, as an early understanding of the scoring system changes how you approach a match tactically.
Competition preparation does not require a dramatic change to your training. The fundamentals that serve you in the gym will serve you on the mat. If you are still building your foundation, the CNX BJJ beginners section covers the core positions, movements, and concepts you need to compete with confidence at white belt.
In the two weeks before the event, reduce the intensity of your sparring rather than increasing it. The goal at this stage is to arrive healthy and sharp, not to achieve a breakthrough in training. An injury in the final week before your first competition is demoralising and entirely avoidable.
