I came across this Col because it is described in the Altigraph - Profils des Cols des Pyrenees Volume 2 Pyrenees Est. Always recommended anyway as a source of climbs the Altigraph series of books. But the Col de Portus stood out because the last 10 km of the profile was marked in red and black only; so difficult! It also says it averages 9.5％ over the last 10 km. What it does not mention is that the road can hardly be called asphalted in these last 10 km. Yes, you can see that the road used t... read more

I came across this Col because it is described in the Altigraph - Profils des Cols des Pyrenees Volume 2 Pyrenees Est. Always recommended anyway as a source of climbs the Altigraph series of books. But the Col de Portus stood out because the last 10 km of the profile was marked in red and black only; so difficult! It also says it averages 9.5％ over the last 10 km. What it does not mention is that the road can hardly be called asphalted in these last 10 km. Yes, you can see that the road used to be this, but almost every trace of asphalt has decayed. Fortunately, I knew this beforehand and had gravel tyres fitted to my bike. And that was necessary, especially for the descent. The poor road surface makes it feel even heavier on average 9.5％ and on stretches 11-12％. You can see it in the speeds on strava on this climb, which are low. There are few turns in the climb, it undulates a bit along the mountainside, but the scenery is beautiful. Very open, though, so watch out on hot days. The top of the col itself is not very special, a sort of crossroads on a mountain meadow. However, you can even take a gravel path that takes you 150m higher. But even that ends a bit oddly in a kind of meadow.

Deze Col kwam ik op het spoor doordat deze beschreven staat in de Altigraph - Profils des Cols des Pyrenees Volume 2 Pyrenees Est. Sowieso altijd een aanrader als bron van beklimmingen de serie boeken van Altigraph. Maar de Col de Portus viel op doordat de laatste 10 km van het profiel enkel met rood en zwart was aangeduid; moeilijk dus! Er staat ook bij gemiddeld 9,5％ over de laatste 10 km. Wat er niet bij vermeld wordt is dat de weg in deze laatste 10 km nauwelijks nog geasfalteerd te noemen is. Ja, je kunt zien dat de weg dit vroeger was, maar bijna elk spoor asfalt is vergaan. Gelukkig wist ik dit wel vantevoren en had gravel banden gemonteerd op mijn fiets. En dat was nodig, zeker voor de afdaling. Het slechte wegdek maakt het dat de gemiddeld 9,5％ en op stukken 11-12％ nog zwaarder aanvoelen. Je ziet het wel aan de snelheden op strava op deze klim, die ligt laag. Er zitten weinig bochten in de klim, het golft een beetje langs de berghelling, maar de omgeving is mooi. Wel erg open, dus pas op op hete dagen. De top van de col zelf is niet heel bijzonder, een soort kruispunt op een bergweide. Je kunt echter zelfs nog een gravelpad nemen die je 150 m hoger brengt. Maar ook dat eindigt een beetje raar in een soort weiland.
