Any cycling enthusiast always talks about the San Lorenzo pass as one of the toughest mountain passes in Asturias, although it is necessary to distinguish between its two sides, as the side from San Martín de Teverga is more demanding than the one from La Riera, although both are tough.
The ascent begins with slopes of around 9-10％, and peaks of 14-15％, which go up the slope with several horseshoe bends that give this stretch a very beautiful alpine look for the first 3 kilometres. At Las Morteras the gradient eases off and there is soon a short break to get ready for the central part of the climb, which is undoubtedly the hardest part of the climb.
For another 3 kilometres the average gradient exceeds 10％ and on reaching Orderías the maximum ramps reach 14-15％.
Once this toughest part of the pass is over, we have practically completed the most demanding part of the ascent and another gentle stretch helps us to recover to face the last part with gradients of 9-10％ again. With this last attack we managed to overcome this demanding ascent to the San Lorenzo pass on the west side from the Somiedo council.
Cualquier aficionado al ciclismo habla siempre del puerto de San Lorenzo como uno de los puertos de paso de mayor dureza que hay en Asturias, si bien hay que distinguir entre sus dos vertientes, la de San Martín de Teverga y esta de La Riera, siendo ambas duras aunque con distintas características.
La ascensión comienza ya con pendientes en torno al 9-10％, y picos del 14-15％, que remontan la ladera con varias curvas de herradura que imprimen en este tramo una estética muy alpina y bella durante los 3 primeros kilómetros. En Las Morteras cede el desnivel y pronto se encuentra un pequeño descanso para afontar la parte central del puerto que, sin duda, es la más dura.
Durante otros 3 kilómetros el desnivel medio supera el 10％ y al llegar a Orderías alcanzan sus máximas rampas del 14-15％.
Superada esta parte más dura del puerto prácticamente tenemos la parte de la ascensión más exigente hecha y otro tramo de poca pendiente nos ayuda a recuperar para enfrentarnos a la última parte con pendientes de nuevo del 9-10％. Con esta última acometida logramos vencer esta exigente subida al puerto de San Lorenzo por su cara oeste desde el concejo de Somiedo.
Beautiful climb in the north of Spain . This 10 km long climb has been the setting of cycling races several times in the past . In 2019 during the round of Spain they rode over it . The climb is very erratic and it is an alternation of very steep gradients up to 16％ followed by less steep stretches even slightly downhill.
The climb consists mostly of double figures but nowhere are these strips longer than 3 km and so the average cyclist can regularly find some respite. The scenery is fantastic with on the way and on top of the small parking lot a beautiful view on the many Puertos in the neighborhood. The fauna would be the most fantastic and diverse of all Spain. This col is also situated in the Somiedo nature park of Cantabria. If you are in the area don't miss it and the road surface is very good.
Prachtige klim in het noorden van Spanje . Deze 10 km lange klim is in het verleden meermaals het decor geweest van wielerwedstrijden . In 2019 is men tijdens de ronde van Spanje er nog overgereden . De klim is erg grillig en het is een afwisseling van zeer zware stijgingspercentages tot 16％ gevolgd door minder steile stroken tot zelfs licht bergaf.
De klim bestaat veelal uit dubbele cijfers maar nergens zijn die stroken langer dan 3 km en zodoende vindt de doorsnee wielertoerist er regelmatig wat adempauze . Het decor is fantastisch met onderweg en boven op de kleine parkeerplaats een prachtig zicht op de vele Puertos in de buurt. De fauna zou er de meest fantastische en verschillende zijn van gans Spanje. Deze col ligt dan ook in het Somiedo natuur park van Cantabrië. Als je in de buurt bent mis hem dan niet en het wegdek is zeer goed.
