People often ask how fit they need to be for the Welsh 3000s. There isn’t a single distance, pace or fitness test that gives a useful answer. What matters is how that fitness holds up on rough mountain terrain for a very long time.

Crib Goch gets most of the attention before a Welsh 3000s attempt, but it is rarely where I see the biggest problems. Three steep, rough descents later in the route can have far more effect on pace, fatigue and whether people carry on.
