The Ice Master M Trail Running Crampons by Camp

Crampons: a critical piece of equipment for the Aneto-Posets Great Trail

The first Aneto-Posets Gran Trail was held in Benasque in July, 2014. The 106km route was set in the heart of the highest mountains in the Pyrenees. Unlike most trail running races, this one takes place in high mountain territory and, in this respect, it is similar to the Mont Blanc Ultra Trail.

Although most of the route can be run, there is a section in the Aneto-Posets Gran Trail which belongs more to the world of mountaineering than to trail running: Salenques valley. Here is how one of the runners (Ramón Ferrer) described this section: “without a doubt, this is the toughest part of the race, due to its verticality and the amount of snow, which was frozen and proved to be difficult and dangerous for the runners. Many chose to wear crampons for this section, but shoe crampons on such steep terrain need to be handled with precaution.”

On the other hand this valley is covered in large rocks that go all the way up to the Vallibierna mountain lakes at km 41 and it becomes almost impossible to run this 20km stretch. The sea of rocks can make even the toughest runners despair, but at a height of almost 2000m, it is also spectacular high mountain terrain, with rocks, more rocks, snow, ice, mountain lakes and stunning scenery.

In a competition of this kind, the organizers request a much longer list of mandatory gear, which means extra weight in your pack. This can be hard to accept for minimalists who are used to taking the least amount of gear on trail running competitions in less extreme conditions. But it is important to understand how quickly things can get complicated in the mountains, if the weather deteriorates. Fog and hail can slow you down or even make you stop, which is not advisable at these altitudes. Evacuating a runner can also be extremely difficult, because unlike most races, there are no marked trails in many sections of the race.

Our Barrabes colleague, Fernando Tomás, completed the race in 23 hours and came 19th. His comments after the race were very clear on the use of crampons: “I gained over an hour at Salenques and I caught up with about 15 runners on the descent. I felt secure on the descent while others were very tense, some even asked me to give them a hand getting down. In spite of the safety rope, there was a serious accident.”

Upon arrival, another runner who reached the finishing line a few minutes after Fernando, claimed to have gained two hours during the same descent over other runners who had reached the col at the same time but weren’t wearing crampons.

And this brings two questions to mind:

  • Can we play with our safety, even our life to avoid carrying 500 grams more in our pack?
  • By avoiding this extra weight do we really reduce fatigue if it means taking 2 extra hours to complete the race and suffer a great deal of tension and effort due to the precarious conditions?
  • Do we actually spend more energy in that time than the energy we save by carrying a lighter load?
Fernando has no doubts: “Not taking crampons for this kind of competition is an unnecessary risk, which ends in lost energy and time; two essential things in an ultra-trail. Of course, you must optimize the weight of your pack, but it’s easy to distribute the 500 grams properly, so that they don’t interfere during the race and the benefits they offer in technical areas is invaluable."

Micro crampons are designed to be used on flat terrain – let there be no mistake. They are almost totally useless if used on a steep slope with hard or frozen snow. These micro crampons were designed to prevent slipping over when walking in snowy towns and villages. They may prove to be effective in competitions with flat trails, but on alpine terrain, such as that found in the Aneto-Posets Gran Trail, they are useless.

However, there are two models of crampons on the market that have been specifically designed for mid to high mountain competitions. These crampons are made for shoes and fit like a glove. They can also be used with a trekking boot in certain situations and on uncomplicated terrain. The spikes are similar to a those of a trekking crampon and they are lighter, although not as light as a micro-crampon.

Fernando Tomás used the medium sized Ice Master by the Italian brand, Camp (approx. 480 g). There are four sizes available.

The attachment system developed by Camp makes it extremely quick and easy to put these crampons onto trail running shoes. Just slip in the toe and pull the rear rubber tab over your heel. It feels as if it wraps round your foot rather than being tied into strap crampons.

It’s important to ensure the rear rubber heel has been pulled upwards so that the chains between
