Being in a crucial point of the spring for the stage-racers, but also right before the Ardennes classics, there is a wide variety of riders licking their lips at the opportunities the hard racing provides.

Prologue: Hondarribia - Hondarribia, 7.5Km
The opening day of the Itzulia. It’s a short prologue and it’s very
explosive. Only 7.5 kilometers, but they feature some climbing, descending and
tight streets in the middle of Hondarribia. It will set some early gaps and order in the general classification.

Stage 1: Leitza - Viana, 207Km

Stage 1 Finale
The first road stage of the Itzulia is an interesting one. It can have
different scenarios, and the first is of a possible breakaway win as the start
of the stage is quite hard and favourable for a strong group to go up the road. The last two thirds of the stage are not as complicated, but they do
feature some climbing which may make things difficult for those looking to
setup a sprint.
It won’t be steep, but nevertheless will be a 12.7Km-long climb which
will summit with 29 kilometers to go, and then the final kilometers are very
rolling which provide some terrain where attacks may happen. The final 15 kilometers feature some rolling hilltops which can be used for attacks and prevent a bunch sprint, but if one is to happen this will be the only stage.

Stage 2: Llodio - Amurrio, 181Km

Oppelora (30Km to go; 1.1Km at 13.1%) & Ozeka (23Km; 3.6Km at 7.3%)

Stage 2 Finale
Stage two, the third day of the race will be a very tricky one, it does not feature a single long climb, however it does feature a set
of short and steep climbs which will be ridden twice and have the potential to
blow up the race.
The two main features of the stage are the Opellora and Ozeka climbs.
Both will be ridden twice as there will be a loop. The final time they’re
ridden, they’ll summit with 29 and 22 kilometers to go, well within the range
of a decisive GC attack. Opellora features 1.1Km at 13.1% making it an incredibly
steep ascent which will decimate most of the peloton, and later at Ozeka (3.6Km
at 7.3%). The 500
meters at 10% with just 5 kilometers to go are more than enough to be a launchpad for a stage win too. The
rest of the stage will have a mostly false-flat downhill into the finish line
in Amurrio.

Stage 3: Vitoria-Gasteiz - Zamudio, 185Km

Vivera (22Km to go; 6Km at 6.2%)
Stage three has 186
kilometers and heads into the outskirts of Bilbao where the Alto del Vivero
will be the main feature of the stage. The stage start is flat, and 65
kilometers in the riders go into the climbs, the normal rompe-piernas terrain
of Spain.
There will be two ascents that will mark the stage. The first comes with
38 kilometers to go, Urruztimendi. It is 1.9 kilometers long and averages
10.5%, another steep and sharp ascent where the peloton will suffer to go up. Through a non-traditional side, but the Vivero will be climbed once
again and it summits with only 19 kilometers to go, it’s a 6-kilometer climb which doesn’t feature a high
average gradient, however it hides a very steep start which has 2.2 kilometers
at 10.6% average grade and much superior gradients at points. The stage then features the descent off the mountain and a 10-kilometer
flat section before the finale in Zamudio.

Stage 4: Zamudio - Mallabia, 163Km

Karabieta (13Km to go; 6.8Km at 5.4%)

Stage 4 Finale (600m at 10.5%)
3400 meters of climbing in the penultimate stage of the Itzulia. A raw
day with climbing from start to finish, nowhere to hide. However, with the
queen stage ahead, it may be a more conservative day between the GC riders,
only the road will tell. The day starts off with a trio of small but sharp hilltops which will
likely see a strong group go up the road.
Between 70 and 35 kilometers to go there will be a long sequence of climbs, which will be a warm-up to Karabieta. The most dangerous climb of the day will be Karabieta, which is 6.8
kilometers long at 5.4%, but as many climbs in this race, the average is very
deceptive. It is a climb of two halves, separated by a flat section. The first
half has 3.1 kilometers at 8.6% and it is hard enough to see serious attacks.
The climb summits with 13 kilometers to go.
The riders won’t be able to relax towards the line though, as the final
kilometer is steep and should see gaps as the riders will go all-out into the
line as it features steep ramps. The final 3 kilometers are generally uphill,
but it’s specifically the final 600 meters which are dangerous as they average
10.5%, making for a very special kind of sprint.

Stage 5: Eibar - Arrate, 135Km

Alto de Arrate, Usartza (2Km to go; 4.5Km at 8.6%)
The queen stage of the Itzulia will once
again go up the Alto de Arrate where the biggest differences can be made, in
what is a very explosive stage with 3500 meters of climbing in 135 kilometers. The first hard bits come with 96 (2.8Km at 10.5%) and 83 (5.2Km at 7.3%)
kilometers to go at the summit of the two hard opening ascents, which can be used for an attempt to raid the race.
From there on the first climb of the day takes play which is the
Krabelin, with 39 kilometers to go. It’s a gruesome climb with very
steep ramps where W/Kg is the only thing that matters, not an overly long
effort, but it’s the hardest climb of the race and serious attacks can come
here.
The finale of the stage and the race sees the riders go up Arrate once
again. 4.6Km at 8.5%, the gradients aren’t hard but it’s nevertheless a hard
climb, at the end of a very explosive day. At the summit, the race should be
decided.

- Hmmm, "... I just gained 30 seconds purely off the bike. Because it's really a big, big improvement compared to the previous bike". Is that marketing for Specialized or serious valid hype, or something in between? Very likely the former.flyer14-11-2026
- Nothing revelatory or controversial. Why do we have to report on Bruyneel's or Armstrong's thinking. It's a shame and enough that the Move's on TV and that people watch it .flyer14-11-2026
- Makes sense that training from home is a big asset or advantage but it's still remarkable that he can put in three quality majors and not pay some heavy price for the exertion. I wish he would have won that tour stage that his crash while leading allowed Carapaz the win. He's a darn good rider and teammate.flyer14-11-2026
- Sounds like we all agree with the over under exaggeration: "The German’s signing does not guarantee that Evenepoel will win the Tour in 2027. "flyer14-11-2026
- Seixas appears to be that good but if he isn't (an absolute rival to Pogacar) he would have plenty of company in rising stars that did not go on to fully meet the expectations of many. That Pogacar wasn't the greatest (as great) sooner can't be transposed onto another's development. It may be not that simple.flyer14-11-2026
- I agree that, for Evenepoel, the Euro championship is overshadowed by the slightly off Lombardia and Worlds. However, I disagree that "Ciccone also made a serious mistake at the European Championships" because I don't think he had a win in the bag although he could have won with a perfect bike throw. Guesswork about the finish is not evidence by me for some serious mistake. Sometimes you just barely lose - although Ciccone's sourpuss about it persona was serious.flyer14-11-2026

- Skipping the 2027 TDF would be fine in my opinion, and if so, it further reveals that him racing it in 2026 was a good decision. Seixas speaks confident, almost cocky, these days (not meant to be a criticism) and I find it a tad humorous that people (rather commentators) continually chide and advise on how Decathlon should direct and manage Seixas when Paul seems to be calling all his shots since well before this year's TDF.flyer14-11-2026
- Well I just watched this and I thought it was great! If you’re a Pogi fan, like me, you’ll enjoy it. Even if you’re not necessarily a Pogi fan I still recommend it. There’s plenty of new stuff I didn’t know about and I’m a Pogi-maniac! Nice interviews with Pogi & Matteo Trentin too.Lozza14-11-2026
