PREVIEW | Giro d'Italia 2023 stage 13 - First day in the Alps sees three massive climbs and expected GC chaos
Cycling
Preview. The Giro d'Italia reaches the Alps, at long last! Stage 13 has suffered last-minute route changes, but it is still a fierce day that will set significant differences among the riders battling for the overall classification.
The Giro d'Italia will head into Switzerland in the 13th stage for a high-mountain finale at Crans-Montana. This is perhaps the most challenging day of the race. It may be contested with stages 16 and 19, however, this being the first of the three gruesome mountainous days it will be key for the overall classification, and surely expose weaknesses within some of the GC riders.
Estimated start and finish times for Giro d'Italia stage 13: 11:00-17:15CET
Stage 13: Le Châble - Crans-Montana, 74kms
The first two thirds of the stage have been cut off due to bad weather, changing the stage's appearance for a second time. The riders now skip the Col de Gran San Bernardino altogether and will take to the start in Le Châble, almost at the base of the Croix de Coueur, for a total distance of only 74 kilometers.
This is an insanely hard climb. Most will know it as the ascent to Verbier where Alberto Contador has in the past put in a much-discussed performance, however here the riders reach the village and keep climbing. Many switchbacks until that point, but then it rises into the Alpine. The final 6 kilometers average almost 10% and it's summit lies at almost 2200 meters of altitude.
Croix de Couer: 15.5Km; 8.6%; 60Km to go
The descent is equally technical, just as steep but even longer. The riders lose a whole 1700 meters in altitude, a mental difference. Through the Rhône valley then the run-up to the final ascent is pan-flat. There won't be much fight for positioning as the race should be split to bits at this point, and the climb is long and very constant.
The 13.1 kilometers into Crans-Montana don't see many gradient variations, with a steady 7% present most of the climb. However in total the climb has 15 switchbacks and most of them are in the first half. This could be called an explosive climb but at this point of the stage it's a test for survival. Gaps will easily be made and I would say early in the climb.
Crans-Montana: 13.1Km; 7.1%
The Weather
Map Giro d'Italia 2023 stage 13
Low temperatures up the mountains. It won't be an easy day to deal with, possibly some southern wind high up but this time around that won't prevent attacks, the most important factor will be to put on the jackets at the top of both passes otherwise the next few days may be very complicated.
The Favourites
Geraint Thomas - INEOS have set their foot. Today they had the opportunity to put other teams under pressure with De Plus and Arensman but chose not to. An all-in for Geraint Thomas, the Welshman is back to his best form and is motivated. This will be a very important test, he is in the lead of the race and INEOS is likely to control most of the day, but with such a small gap back to Primoz Roglic it won't be easy to deal with the pressure.
Primoz Roglic - The Jumbo rider is in the perfect position, and on this day can make a difference. I reckon the mammoth mountain stages won't favour him much however he is in good form, and with Sepp Kuss who should be able to provide good support in this terrain. It will be a test, he shouldn't risk too much, but in the final climb there is room for attacks and differences.
João Almeida - Almeida will be in his terrain with the very long ascents. The final week is where I expect him to make his moves but every second matters and he will nevertheless attack if there is the opportunity. He will have to be cautious in the descents, and this will also be an important day to see how UAE is comiting to their leader.
In this terrain it'll be a matter of survival for some, and form testing for others. Andreas Leknessund and Aurélien Paret-Peintre are still riding within the best at this point and this will be a key day to understand if they can fight for the Top10. I would put Eddie Dunbar and Thibaut Pinot in a similar position as they are not at this point Grand Tour specialists - although I reckon their biggest obstacle will be the final week.
Hugh Carthy will likely try to take back positions after a rough first week, Lennard Kämna will be hoping to be past his illness and be ready to fight for a Top5, and Bahrain will have a better onlook on which of their riders can remain in the battle for the top places. Damiano Caruso has so far looked very good and will love this terrain, Jack Haig and Santiago Buitrago are wildcards to be seen.
As for the breakaway, it does stand chances in this day but it won't be easy. It's a day of pure high mountain climbing and only a very strong climber can take it. Jay Vine and Brandon McNulty are two clear cards to hint at on such opportunity, Ilan van Wilder and Lorenzo Fortunato spent quite a lot today in the breakaway but tomorrow will have a day that suits their climbing abilities better.
Prediction Giro d'Italia 2023 stage 13:
*** Geraint Thomas, Primoz Roglic, João Almeida
** Damiano Caruso, Hugh Carthy
* Lennard Kämna, Jack Haig, Santiago Buitrago, Jay Vine, Brandon McNulty, Lorenzo Fortunato
** Damiano Caruso, Hugh Carthy
* Lennard Kämna, Jack Haig, Santiago Buitrago, Jay Vine, Brandon McNulty, Lorenzo Fortunato
Pick: Geraint Thomas

- big rival … ridiculous.Ketterechts07-11-2026
- It would be great if the World Champion's jersey could be rotated among McNulty, Simmons, and Jorgenson. They threaded the needle perfectly. If each hadn't done exactly what he did, exactly when he did it, the race would have gone to one of the more heralded superstars. That said, how nice that this humble and hardworking guy gets his moment in the sun.
MarkFour07-11-2026 - This is a really interesting idea, which, if well prepared could even be very successful. Very little money needs to be involved for a first season and any success could lead to rapid interest from sponsors.Jumpyjohn07-11-2026
- Hmmm, you seem to have a very convenient black and white view of things. Perhaps you haven’t been around much to discover how complex problems can become over time with people who know how to control, manipulate (or worse) others so gradually or subtly that you arrive at an irresolvable situation before you realise. This is how many inconveniences get introduced to the young, naïve, passionate or “desperate”, knowing they are not armed, protected or strong enough to defend themselves once it’s too late. Why do you think omerta culture is so widespread, why do you think so many people continue to go through so many awful things in life that others can’t understand anyone getting into? Life may be far more jolly for you but you would do well to understand (or reflect more on) the real world to refrain from being so quick to criticise those in a hard spot that may have genuine reason for speaking out.Jumpyjohn07-11-2026
- Seriously do you think when somebody gets into a serious accident, the ambulance is called by the hurt person?🤦 there is always a buddy system in place for a risky job. police , firefighters etc so that if someone gets hurt, the other call that in.abstractengineer07-11-2026
- I get the point totally. We live in the snowflake society where some riders forget they are getting paid to ride and get results. When they have a few issues they try to look outside of the real issue instead of themselves. It odd so many of the team are making no complaints and getting on with their job. If you do not like what you do find another job simples. Tough love as my mum would say.paultryan200207-11-2026
- many people advise him to grow slowly and rather do giro and/or vuelta instead of tdf. but i can totally understand that he is not satisfied with taking over once pogi declines, but instead beat him in his prime. so if he goes for tdf again, i‘m all for it. let‘s hope that pogi recovers soon!Ketterechts07-11-2026
- So gracious to offer something no-one would be prepared to pay for. The Giro is not the Tour and doesn’t command the same interest or attract the same “elite” (those willing to pay to be a part of something they consider has ego boosting potential). Roadside viewing will always largely remain free for everyone outside circuits. Introduction of a symbolic entrance to mountain climbs is worthy of exploration. Asking 1-2€ isn’t going to repulse real fans (most will spend 50-100€ on their outing that day all things included) but will prevent a portion of the total knobhead thrillseekers who will join in any large gathering as long as it’s free, just because they’re attracted to crowds, without which it it difficult for them to work up their anti-social behaviour.Jumpyjohn07-11-2026
- How is radio going to help when someone went over a cliff or bridge or off the roadside into a forest unnoticed and is laying there unconscious?Jumpyjohn07-11-2026
