Sestriere sits at 2,035 metres above sea level in the Piedmont Alps, nineteen kilometres from the French border at Montgenèvre, and at the intersection of three mountain valleys that cyclists have been arguing about for seventy years. Fausto Coppi won here in the 1940s. The Giro d'Italia has finished here repeatedly. The 2026 Giro d'Italia Women uses it to close Stage 8 — the race's final day of climbing, arriving on Sunday.
The climb is not the longest in the Dolomites or the steepest in the Alps. What Sestriere offers is position: a summit finish at altitude, above the tree line, with a long approach from the Susa valley that exposes every rider's legs by the time the gradient rises for the final push. It is a race-deciding climb not because it is extreme but because by the time you reach it, you have already been broken in two or three places, and there is nowhere left to hide.
The Climb
The most-used approach for Grand Tour stages is from Cesana Torinese, a village in the upper Susa valley northwest of Sestriere.
From Cesana Torinese: approximately 12 kilometres at an average of 5.5%, with the gradient building toward the summit. The road is wide, smooth, and fully exposed above Sauze d'Oulx — the last tree cover disappears about halfway up. Wind is the variable: a headwind on the Cesana approach adds difficulty that the gradient profile does not advertise. The final two kilometres to the summit arrive through a hairpin sequence with views across the Via Lattea ski area, and the road finishes in Sestriere's central piazza beside the famous cylindrical tower hotels.
From Pinerolo (alternative approach): a longer and more historically resonant option. The road from Pinerolo runs through the Chisone valley, climbs through Fenestrelle, and approaches Sestriere from the south via Colle delle Finestre (2,178m) and Colle dell'Agnello — a much harder and longer day that adds two additional alpine passes. The 2023 Giro men's pink jersey changed hands here when Geraint Thomas cracked on the Finestre gravel sector. This is the route for athletes building a serious altitude block, not a single-day ride.
Recommended Rides
The classic loop — Cesana → Sestriere → Montgenèvre → Cesana (35km, 1,100m climbing): Leave Cesana and climb to Sestriere, continue over the pass, drop into France to the Col de Montgenèvre border crossing, return to Cesana along the valley. One day, two countries, two Giro-significant summits. Best attempted on a fresh day as a single loop rather than as part of a multiday block.
The Stage 8 descent simulation — Sestriere → Pinerolo (55km, 1,900m descending): Ride the Stage 8 route in reverse, starting at the summit and descending the Chisone valley to the Piedmontese plain. Efficient use of a driving day — you can park one car in Pinerolo, take the second up to Sestriere, ride down, and return to base in the afternoon. No climbing required; technical descending skill at altitude is the relevant variable.
The Via Lattea circuit — 3-day alpine loop: Sestriere sits at the hub of the Via Lattea ski interconnect — the largest ski area in the Piedmont Alps, which translates in summer to a network of road passes linking Sauze d'Oulx, Cesana, Clavière, Montgenèvre, and Sestriere. Riding the full circuit clockwise takes two to three days at a steady alpine pace. The roads are quiet, the altitude consistent, and the logistical base in Cesana or Oulx makes a relaxed centre.

June through September is the practical riding season above 1,800 metres. Sestriere's summit sits in snow into May most years, and the access roads from Cesana are typically clear by mid-June. July and August see the longest riding days and the warmest temperatures — expect 15–20°C at altitude, cooler in the evenings. The roads are busiest in August when Italian cycling holidays peak.
Stage 8 of the 2026 Giro Donne arrives on June 7 — early in the season. Athletes building a June altitude block will find the roads clear, cool, and uncrowded.
Base Options
Cesana Torinese is the practical base for Sestriere riding. The town sits at 1,350m, has a functional hotel and self-catering infrastructure, and provides direct road access to the Sestriere climb, the Montgenèvre crossing, and the Chisone valley approach. It is quieter and less expensive than Sestriere itself.
Sestriere is the ski resort — functional, wind-exposed at altitude, convenient if you want summit access. Hotels, restaurants, and a lift infrastructure that operates in summer for mountain bikers. The piazza around the famous cylindrical hotels is where the Giro stage finishes.
Pinerolo, lower in the valley, works as a base for longer days using the full Chisone valley approach. More urban, more service infrastructure, better for athletes not doing altitude training specifically.
How to Get There
Fly into Turin (Caselle) — 90 minutes to Cesana by car. The autostrada runs to Torino's western suburbs; from there the SS24 climbs the Susa valley past Susa and Oulx to Cesana. Car hire is essential — there is no cycling-practical public transport to altitude in this valley.
From France: Montgenèvre is on the French border, accessible from Gap, Briançon, and the Route des Alpes network. Athletes already in the French Alps — Grenoble training camps, Alpe d'Huez base — can ride to Sestriere directly via Montgenèvre.
Altitude and Training
Sestriere at 2,035m is at the threshold of meaningful altitude training. Three to four nights here combined with riding days to 2,500m and above (the Agnello and Finestre passes take you there) provides genuine hypoxic stimulus. WorldTour teams have used this area for pre-Grand Tour blocks precisely because of the road quality, altitude, and distance from the Italian media's attention.
What Else to Do
The Via Lattea lift network opens in summer for trail runners and mountain bikers — the same lifts that connect Sauze and Sestriere to Clavière in winter take hikers to 2,500m in summer for ridge walks and technical routes. The Sacra di San Michele — a medieval abbey built into the rocky spur above Sant'Ambrogio, at the valley entrance near Avigliana — is the best rest-day excursion in the region.
Turin is 90 minutes down the valley: Juventus stadium, the Egyptian Museum, the Mole Antonelliana, and one of Italy's great coffee cultures. It is worth a half-day on an arrival or departure window.
Frequently Asked
Is the Sestriere climb suitable for recreational cyclists? The Cesana approach is manageable for experienced cyclists. The 12km length and 5.5% average are challenging but not extreme at altitude. Beginners should ride with a partner and have a plan for the weather — the summit is exposed, and afternoon thunderstorms in July and August arrive quickly.
How does Sestriere compare to Alpe d'Huez or the Stelvio? Sestriere is longer and less steep than Alpe d'Huez, shorter and less severe than the Stelvio. It rewards consistent climbing rather than explosive power — a time-trialist's climb, which explains why van der Breggen and Vollering's fight should suit it.
Can I ride from Sestriere to France? Yes — the Montgenèvre border is 19 kilometres from Sestriere by road. No customs stop for EU citizens; US and UK visitors need a passport. The descending road to Briançon on the French side is outstanding.
Where do I find training partners in the area? Connect with cyclists already based in the Susa valley via Find Athletes in Pinerolo on ZealZag.
