Corridors of flow – In search of the perfect trail experience.

While religiously sipping hot coffee, my morning started with browsing the new batch of outdoor sports media the night had spawned. Usually it’s the same generic clichés of a runner, biker or climber doing something way out of my reach, while a dreamy euphoric soundtrack helps to convince me of its total awesomeness. The bittersweet sting I get from these video’s helps me convince myself that if I just get through these next couple of days, weeks, months… of being diligent at work, I’ll get my share as well.

I was watching a video of mountain bikers flowing through some ridiculously beautiful trails when I heard the voice over say something that really struck a chord in me. He simply nailed what I’d been thinking but hadn’t been able to put into words:

The Nadri test measures which “load” you can handle in the course of an hour. This helps you judge your level of training. It’s not necessarily about “how hard” you can climb, but more about “how much” climbing you can put out in a timeframe. Look at is as a combination of technical difficulty and volume (how much / how fast / per time); The weight you can give to a performance is described in the score table below. Those with analytical minds can use this spreadsheet to measure the volume and intensity of climbing training over longer periods of time in themselves and others. This can be used to adjust training to more efficiënt levels. Nadri stops at 6C+. I’ve extended his line of scoring using the same mathematical increments.

Example: to cross the Aiguille de la Vanoise you need to score 40 to 70 points; for the Pierre Alain-route on Grand Pic de la Meije South wall in the Encrins you need 200 to 240 points.
