Capable of going anywhere, anytime

A race follows a course someone else has marked. Orienteering takes you from one checkpoint to the next. A traverse is neither. It has a start, an end, and perhaps one place you chose because it looked good on the map. Everything between them is yours to work out.

So the easy way is rarely your way. A road may run straight to the lighthouse. A run along it is a long run, not a traverse. You leave the road for the ridge and the forest, because that is where the land is worth seeing. You can join a traverse someone else has organised. You can also plan your own from a map at home. Either way, you decide where you are going, and then you work out how.

A traverse has no fixed sport. You pick what fits the distance, the ground and what you can do. Thirty kilometres of forest and ridge is a run. A hundred kilometres of gravel to the coast is a ride. A frozen lake in February may be a day on skis. One day, a coast of small islands may be a day in a kayak.

Often one way is not enough. You ride the gravel to the foot of the ridge. Then you lift the bike onto your shoulder for the steep part. You run to the shore, and you swim across a river mouth. Every way across runs on the same engine. Your heart and lungs grow from the hours you put in, whatever the sport. The muscles of each movement do not cross over. They have to be trained in that movement. The more sports you move well in, the more of the map is open to you.

A map is flat, and the land is not. Halfway along the ridge, the ground falls away in a cliff. On the map it was a thin brown line. In front of you it is ten metres of wet rock. You do not go down it. You follow the edge until the slope eases, and you find a way round.

That is the skill a traverse adds. You read the land as you go. A dry slope of grass is a safe way down. Loose stones on a steep slope are not. A wide, slow river can be swum. A narrow one, fast and brown after rain, is a reason to run upstream to the bridge. The detour is not a failure. It is how you arrive.

On a road, an engine is enough. Off it, you need more. You haul yourself out of a river onto rock with your arms. You carry a bike up a slope of boulders. You land on ground that tilts a new way with every step. Strength does this work. Endurance training does not build it, because strength is built by a heavy load. That is why we train it with kettlebells. You lift and swing a kettlebell with your whole body at once.

Range matters as much. Range is how far your joints move under control. It lets your hip lift your foot high onto the next rock. It lets your shoulder reach for the ledge above you. A stride and a stroke use only part of each joint's range. Yoga takes your hips and shoulders to the ends of theirs. Then the ground that asks for them does not stop you.

Strength and range give you control of your body on any ground. That control is what lets you trust it. You set off into a day you cannot fully predict. You know your body will carry you through whatever comes.

It is June now. You leave the house at six with water, food and a light jacket. Someone at home knows your line and when you expect to call. You run the forest at base, the steady effort you could hold for hours. You climb to the ridge, and the view is as good as the map promised. You find your way round the cliff. The river is low and slow, so you swim it. In the evening the headland narrows, and the lighthouse stands at the end of it. You touch its white wall. Then you turn round and look back at the ridge, small and blue now. A body that brought you here can take you anywhere.
