Estado del terreno en las salidas de montaña (BTT)

El estado de los caminos propiamente, (sin contar con la climatología), podríamos considerarlo como un valor objetivo, aunque siempre nos podrán asfaltar un trozo de camino, allanar unas regateras, o limpiar de pedruscos un tramo, podemos pensar que mas o menos los trazados se mantendrán siempre de manera parecida.
 

La lógica nos anima a pensar que el estado del terreno influye de manera crítica en la valoración de la dureza de una salida

En cierta manera así es, pero los estudios de mas de 100 rutas diferentes entre personas de distintos niveles, nos demostraron, no sin cierta sorpresa, que la influencia de ese dato era menor de lo esperado.

Track points recorded per Km

Track points recorded per Km

The points per Km that GPS records are a decisive factor in the collected data reliability.

The total recorded points do not affect to the total covered Km, but they do in the accumulated rised/descended meters.

If there are recorded a few points per Km, we will have poor information, so that the total meters accumulated will be less than the real ones. If we have a lot of points, then we will have too much information and too much accumulated mistakes, so that the accumulated meters will be more that the real ones.

Accumulated rise/descent meters

The total rise/descent meters that IBPindex show in the first analysis (repaired analysis) is strictly the sum of the GPS registrations. The GPS receptors usually accumulate some more rise or descent meters due to the sattelites.

In a second analysis (optimized analysis) it is applied a slope corrector that makes a more real value. The newest receptors are more and more precise and so they accumulate less mistakes.

Track mistakes
 
Errores de track

 

 

IBP system detects and corrects automatically heigh mistakes of the tracks.

The GPS regists, sometimes, track points with an excessive heigh mistake margin. This peaks are easy to see when whe represent the track in a graphic.

The mistake correction is done in two times, or two track analysis. In the first one, it is replaced the mistaken heighs with other ones calculated in that point. In the second one it is calculated the IBP index in a free mistake track.

How to use IBP index

Analyze your usual routes, those that you know best, then compare the results with other less knwon routes. This will shape you a personal scale that will let you know the difficulty of other routes that you haven't done yet.
