Hertfordshire has a steady BJJ calendar, with events spread across the county and nearby towns including Watford, Barnet and Rickmansworth. The EJO Hertfordshire Open, run by Essex Jiu Jitsu Open, is the most regular event.
Empire Grappling has held its Southern Open in the area, and Ethos BJJ runs interclub events that suit newer competitors. Events offer both Gi and No-Gi divisions, and many include absolute divisions. The summer months have been the busiest time for events.
