Traveling fast over complex technical terrain requires a high level of technical ability and the endurance to support it. These two quite divergent capabilities need to be developed over years of practice. Omitting either limits your potential.

In no organized sport do the participants have to endure days of struggle just to get to the starting line of their event. The option to drop out of a race that is going badly does not exist for a climber halfway up a big route, and may entail more risk than pushing on. A team of volunteers will not be waiting with warm blankets and hot food at the next bivy ledge. When you reach the summit, having overcome the challenges that inspired you for months or years, you are not at the finish line. The race is not over. You can't relax and let your guard down like a normal athlete.

The simpler we make things, the richer the experiences become.

The descent is often as much (or more of) a challenge as the climb.

In the mountains, fatigue is the biggest controllable limitation that will come between you and success.

Historically, many of the great names in alpine climbing seemed to have just gone climbing as training. In fact, the model alpinist has often portrayed himself in literature as a half-crazed nonconformist, living life on the edge every moment he's sober enough to climb. It is true that amazing feats of skill and daring have been accomplished using this rather random approach. For some climbers that "life on the edge" approach may be the only way they can accomplish these feats, but there are far better methods to prepare for the challenges of alpine climbing.

On big routes in big mountains, speed equals safety.
