Intro: Alcohol is often a silent saboteur in the world of fitness — impacting sleep, recovery, hormone balance, hydration, and mental clarity. But what if just over four days without it could give you a noticeable edge?

This RB100 challenge invites you to go 100 hours alcohol-free — a focused reset to help you reconnect with your training goals and recover better.


Why 100 Hours?

100 hours (about 4 days + 4 hours) is enough time to:

  • Stabilise hydration and electrolyte balance
  • Improve sleep quality and REM cycles
  • Reduce inflammation and improve recovery
  • Notice energy level and mood improvements

What to Expect

  • Day 1–2: Cravings or routine triggers (social, evening wind-down)
  • Day 3: Clearer sleep patterns, more stable energy
  • Day 4+: More focus during workouts, improved digestion, and mental clarity

Tools for Success

  • Track it: use a countdown timer or habit tracker app
  • Replace the ritual: fizzy water, kombucha, or herbal tea
  • Tell someone: accountability increases success
  • Move more: exercise helps reduce alcohol cravings
