Cycling 100km is more than just a ride it’s a physical and mental milestone. For some, it’s a Sunday classic. For others, it’s a first serious test of endurance. Either way, the Bike 100km Challenge is an iconic journey through effort, pacing, and resilience.
“Distance reveals discipline. It’s just you, the road, and the will to keep going.”— RB100.Fitness
Why Take on 100 Kilometres?
- Cardiovascular endurance: Long, steady-state effort develops your aerobic base.
- Mental toughness: Overcoming fatigue and saddle time requires focus.
- Muscular endurance: Legs, core, and stabilisers are constantly engaged.
- Calorie burn: Expect to torch 1,800–2,500+ calories depending on effort.
- Scenery therapy: The miles give space to think, breathe, and reflect.
Whether you’re on a road bike, gravel rig, or smart trainer, the 100km mark is the cyclist’s rite of passage.
How to Approach It
Option A: One-Day Ride
- Plan a loop or out-and-back route totalling 100km.
- Fuel every 30–45 minutes with snacks and hydration.
- Pace yourself — ride conversational for 70%, push for the final 10km.
Option B: Indoor Ride
- Use a platform like Zwift or TrainerRoad to hit 100km on a smart trainer.
- Build your playlist — try the 100 Workout Songs playlist.
- Use fan cooling and set up fuel/hydration within reach.
Option C: Split Over Two Days
If you’re newer to cycling, try 50km one day, 50km the next. You still earn the win.
How to Train for It
- Increase your longest ride by 10–15% each week.
- Do one endurance ride weekly, two shorter rides with effort.
- Strengthen glutes and core off the bike (see: 100 Kettlebell Swings Before Breakfast).
- Cross-train with Zone 2 cardio.
