Dear St Athan Club Member,

The Jiu Jitsu Foundation senior instructors and the competition team are really looking forward to seeing you and your Jiu jitsu club members at the junior randori competition on 27th April. Here is some information and a couple of requests.

In order for us make the day a success we need your help, please:

  • Let you club know competitors weight and if they have relevant experience in judo or another style of jiu jitsu as early as possible. Note that competitors must be registered online via TJJF website by midnight on Wednesday 24th April 2019 (Please speak to Sensei Adam Jenkins to ensure you are registered)
  • Remember that the day is for the children. Encouraging them to fight hard is fine, but please keep the obvious enthusiasm under control as we know that some children can be upset by excessive shouting.
  • Also remember that all instructors, helpers and the organisers are volunteers and are there to ensure your children have the opportunity to compete in a national event. Also remember that they are human and they may make the odd mistake. If you think a mistake has happened please consult the event referee or lead instructor.
  • Please communicate in a calm manner and avoid shouting at the officials who are trained to referee and look after your child’s safety and shouting can also upset and distract the children. We all want the day to be an enjoyable one so I hope you can support all the instructors and helpers to ensure that this happens.

The anticipated timetable for the day is:
