The Future of Fitness Racing? Deadly Sprint REVEALED by Founder Jason Curtis


The evolution of fitness racing just hit another level.


In this explosive episode of On The ROX we sit down with Jason Curtis, the man behind the rapidly growing Deadly Dozen, to break down what’s coming next… and trust us, this changes everything.


Over the last 24 months, Deadly Dozen has grown from a bold concept into one of the most exciting formats in fitness racing — from the traditional track race to the rise of gym-based racing. Athletes, communities, and affiliates have all been part of the journey.


But now… it’s time to accelerate.


🚨 Introducing: The Deadly Sprint 🚨


A brand-new format designed for indoor running tracks, bringing a faster, more explosive race style to the sport:


  • 200m indoor track efforts before each labour
  • Half the distance, half the labours
  • Full intensity, full competition


In this episode, Jason reveals:


  • The full breakdown of the Deadly Sprint format
  • The UK arena calendar (North & South)
  • Key dates and rollout plans
  • The vision behind scaling Deadly Dozen into a true fitness racing system


And that’s not all… 👀

We also get insight into what’s coming next with future developments, opportunities, and “carrots being dangled” that could take Deadly Dozen to another level entirely.


This isn’t just a race.

This is a methodology, a movement, and potentially a cornerstone of the fitness industry.


So the question is…

👉 Can Deadly Dozen become part of the global fitness industry infrastructure?
