New for 2026 · Relentless Hybrid
The Rumble Series has always been a CrossFit floor. Hybrid Edition is the other half of the house. Endurance, engine and grit, run under race conditions on our HYROX floor at Relentless Hybrid.
Race simulations and road shows rather than heats and divisions. You run the real thing, start to finish, with a clock on you.
Relentless Hybrid, Brackenfell. Our official HYROX Training Club and the home of Deadly Dozen in the Northern Suburbs.
Members and non members. Vitality welcome. If you can move for an hour you can start here.
Race Simulation
The Deadly Dozen Sim
Twelve Labours. Twelve 400m journeys. The full race, run inside our four walls.
