Who this suits
Is 3SIX12 24-Hour for you?
- Durability over peak power. It rewards riders who keep turning the pedals long after fresh legs are gone.
- Confidence on technical trail. Tired, wet or in the dark, the descending is where time is won and lost.
- Night-riding nerve. Hours of this are ridden in the dark, and that is a skill of its own.
- A reliable stomach. You will be fuelling on the move for hours, and the day is won or lost on it.
