17. Alto de Trobaniello (Asturias)
A dirty little secret
Vuelta stages such as
this one in 2011 have meant that the Puerto de la Ventana has become part of the standard vocabulary of the Vuelta, although normally its far easier southern face is climbed, and usually (over-)categorised 2, as it is well placed to introduce riders to the Asturian classic climbs - descending it into Teverga, you can turn west to San Lorenzo or east to La Cobertoria. Its northern face, from Teverga, is a very, very respectable
17,0km @ 6,3%, however we aren't here to talk about the long and tricky grind of the known faces of the climb... we're here to talk about it's immediate neighbour, the Trobaniello side, which links almost perfectly to Ventana in much the same way as we say the 2003 Giro climbed Fauniera when in fact it climbed its close neighbour the
Colle d'Esischie. The Alto de Trobaniello is 3,3km of false flat from the Puerto de la Ventana, and also 23 metres higher in altitude. It is steeper, almost as long, and way, way tougher. It's a brute.
Although some figures have it slightly longer at a slightly lower gradient, depending on where they put the
comienza puerto sign, Altimetrias Asturias have the most detailed profile of the climb, seen above, which marks it out at
16,0km @ 7,0%. These figures are pretty serious business in anyone's language, but the big thing to remember with Trobaniello is that
half of it is on sterrato. Hey, back when I first introduced the
hormigón I said that Spain didn't really have the option of cobbles like the Tour has on occasion, and that the Giro had pre-empted it on the sterrato, but I never said Spain didn't have sterrato, just that the Giro was there first. And while Trobaniello is not as steep as, say, Kronplatz, as shown on
this comparison between the two, it is much longer, has more sterrato, and is very much a bona fide ESP category climb all of its own.
The first part of the climb is fairly unassuming, on
fine tarmac through typical Asturian mountain villages. It really eases the riders in as well, with the first 6km, the only ones on tarmac, averaging a mere 4,8%, with the last of these the steepest, at 6,9%. After that, however, apart from a couple of short stretches, it is all sterrato, and it's getting ever steeper.
The stretch of climbing that comes once the sterrato begins totals in at
10km @ 8,3%. For reference, this in and of itself almost matches the stats of the Puerto de San Lorenzo, one of Spain's most iconic climbs and one that is regularly given ESP classification at La Vuelta. But even within this, the gradients find time to gradually turn up the heat. The first 5km of sterrato average 6,9%, which tells you just how tough the final few kilometres are. Another comparison that can be made is to
Izoard, although the Casse Déserte isn't on
agonisingly steep sterrato. A drawback to the use of this climb is, however, that Asturias is one of the wettest parts of Spain, and I can imagine roads like
these get pretty treacherous in heavy rain.
After these 5km comes our first stretch of respite from the dirt roads for the riders - but I wasn't lying when I said that there was no more tarmac. Instead, presumably to give people travelling the route a bit more grip as the road ramps up to its toughest yet, a slope of 18%, there is a brief patch of
hormigón; the second stretch of hormigón also matches up to the steepest ramp on the entire climb, which comes with 3km remaining - a savage 20% awaits. The final few kilometres are truly, truly brutal, a horrific
5km @ 9,7% which, when you bear in mind the surface, is absolutely a killer and will likely tear a race apart. The steepest kilometre is between 12,5km and 13,5km into the climb (so starting at 3,5km from the summit) - this averages out at no less than 12,7%! The final 2km are all at about 9%, but the damage will no doubt by then have been done, so the riders will hardly be en masse as they pass the Capilla de Trobaniello and enter the
final ramps of hormigón. It's a
lonely world up here, before the gradual downhill eventually leads us, back on tarmac albeit in bad condition, to the junction at
Ventana (another photo stolen from Marco Montero).
With its location being in the middle of southern Asturias, there are many, many options for how to include Trobaniello in La Vuelta. However, owing to a lack of significant ski stations or settlements in the area, turning it into a decisive climb may require a bit more work or imagination. Certainly, the climb could be very easily slotted into
this year's queen stage; the descent from La Cobertoria now that the Vuelta is finally climbing its toughest side takes the riders right to the base of the Alto de Trobaniello, and as we already know the
scenic descent from the Puerto de la Ventana takes riders right to the base of San Lorenzo. This gives us a final 110km identical to
this fantasy route, which would surely be the toughest Vuelta stage ever (Cobertoria 10,2km @ 8,5% at 90km out, Trobaniello 16,0km @ 7,0% cresting 65km out, San Lorenzo 11,2km @ 8,0% 29km out, La Farrapona 18,7km @ 5,8%).
Personally, however, I think that it would be better in such a stage if, instead of finishing on a fourth arguably ESP climb (Cobertoria East and San Lorenzo East could both be arguably cat.1 or ESP depending on Unipublic's mood), the finish was instead at
Valle de Lago, a shorter climb from Pola de Somiedo totalling 8km @ 6,1%; while it does feature a couple of very steep kilometres of its own, it is noticeably easier than its predecessors, and brings their summits closer to the finishing line, hopefully enticing attacks on the earlier climbs, especially as the steep slopes of Cobertoria and the brutal sterrato on Trobaniello would surely have decimated domestique fields; I'm not anticipating something as great as Rifugio Gardeccia in the 2011 Giro, but I'm all for trying to replicate that type of layout. Another option would be a false flat finish in Pola de Somiedo,
like this, which would put Trobaniello cresting around 50km from the finish.
If Guillén and co. wanted to get a bit creative, however, they could make Trobaniello the real key climb of the stage by placing it just 17km from the end of the stage, with a finale like
this; using the car parking facilities at the summit of La Farrapona that has enabled them to use it as a summit finish in 2011 and 2014, they could place the finish here and climb it from the Leonese side straight after Puerto de la Ventana, doing a decent Finestre-Sestriere impression; the bad news is that this side of La Farrapona is
also unpaved dirt roads, which
literally only ends at the summit, with the last 2km being at 11%. This would give a final climb of
5km @ 7,9%, with the last 4km sin asfalto. Probably a bit much.
However, if they were willing to use both stretches without padding it out for the race finish, as after all Finestre doesn't get used as a race finish, they could descend from there to Pola de Somiedo and finish at Valle de Lago from that direction, such as on
this rather optimistic route that also features the roadless side of the Puerto de la Cubilla. There is probably not enough room at the Puerto de la Ventana to make Trobaniello a mountaintop finish in its own right, and while there is a small car park at the summit of the Puerto de San Lorenzo (which would mean Trobaniello cresting 36km out) you'd have to think, if they could finish there they would have done so by now. Still, the potential combo of Cobertoria E, Trobaniello and San Lorenzo E back to back must surely have race designers salivating at the prospect of a truly epic GT stage.
