Consejos de material

Prepárate y prueba tu material

La elección de un equipo adaptado es uno de los factores claves del éxito en tu carrera. La ultra resistencia necesita una preparación minuciosa, en la que se incluye la selección del material a llevar.

En el mes de agosto en el macizo del Mont-Blanc, puede hacer mucha calor (más de 30°C), pero puede hacer también mucho frío (hasta -10°C por encima de los 2.000m), llover, granizar o incluso nevar. El material debe permitirte afrontar cualquier tipo de condición y poder pasar una o dos noches en el recorrido, según tu ritmo. En caso de incidente, tu material debe también permitirte esperar el rescate en condiciones de seguridad suficiente.

El UTMB® impone un material obligatorio que todos los corredores deben tener en permanencia con ellos bajo pena de penalización. Se efectúan controles durante las carreras. Tenemos que animar a los corredores a llevar también consigo el material muy recomendado, así como el material aconsejado. Es esencial adaptar el material a tu realidad, probarlo durante las salidas de entrenamiento en condiciones variadas y llevar todo aquello que te pueda ser útil o necesario. El peso es un desafío, pero no seas demasiado minimalista. Optimiza tus posibilidades de éxito y tu rendimiento gracias a una elección sabia.

The ideal trail-running shoe

The IDEAL trail-running sole, powered by Vibram

A good trail-running sole offers light weight, grip and traction. An excellent trail-running sole offers the same features, but over all types of terrain and under all weather conditions.

Requisite features for each TYPE OF TERRAIN

Uphill: flexibility and traction
Downhill: cushioning and grip
Flat terrain: easy "rolling" of the shoe with the foot

Requisite features for each TYPE OF WEATHER

Rain: grip and self-cleaning

Snow: traction and self-cleaning
Dry conditions: cushioning and flexibility

Main characteristics of a shoe for mountain racing

  • PERFORMANCE thanks to effective transfer of the runner's propulsive force to the ground, with minimum energy loss during each stride.
  • PROTECTION through effective cushioning, both to protect the arch against the irregularities of the terrain and to reduce the detrimental effects of the constant impacts on the muscular and skeletal systems.
  • COMFORT thanks to precise distribution of the pressures impacting on the foot, achieved through a sole profile adapted to the terrain and the race.

In a trail-running shoe, 70% of the total value resides in the sole. In "long-distance" races, the priorities are protection and comfort. That is why Vibram soles comprise functional zones designed with human anatomy and the needs of active feet in mind. This approach ensures the best solutions for trail runners over all types of terrain and all distances.

The functional zones of a Vibram® trail-running sole

A reinforced front section provides better protection of the toes against knocks. It is important that the tread continue to the very tip of the shoe to ensure the necessary traction during the last part of the thrust provided by the toes. This phase of movement is particularly crucial during steep climbs in unstable terrain. The tread arrangement shifts progressively with increasingly small and more tightly spaced lugs leading up to the toe bumper.

This is the most important part of a sole for mountain trail running. It must provide a number of complex, often contradictory, functional solutions, such as puncture withstand against rocks to avoid any pain in this very sensitive part of the foot and flexibility, a fundamental feature particularly when going uphill to avoid wasting any energy. These two characteristics must be accompanied by good cushioning, provided by special materials and inserts. Maximum comfort is required for the metatarsus during fast, steep descents. In addition, the sole and the upper of the shoe must function perfectly together in the metatarsus section to ensure good stability, notably in uneven terrain, and effective propulsion under all environmental and weather conditions.

In some cases, this section remains fully in contact with the ground to enhance the roll of the foot, however it can also be raised to improve braking during descents on unstable, humid or grassy terrain.
More rigid inserts and a bracing "high-wall" design in this section reinforce the support of the arch. That is a clear advantage in rough terrain when it is difficult for the sole to remain in contact with the ground. This is a fundamental characteristic for long-distance running to avoid overloading the arch.

During mountain races, particularly during descents in hard, rocky terrain, the impacts on the heels can represent three times the runner's weight. It is essential to provide better cushioning than that found in most standard running shoes, even if that means adding a few grams of additional weight.
Vibram® has developed a cushioning system in the heel section that improves both compression and the distribution of forces from the heel to the toe. The result is lower deceleration values, slower transfer of forces through the ankle and, consequently, much lower impact during descents on very steep slopes. The overall result is a much higher degree of comfort over long distances.
