Stage 17 unfolds with a blend of strategic bursts and relentless climbs as riders chase a potential stage win while GC contenders guard their overall lead. The day centers on a sequence of ascents that test both power and endurance, with the road lifting in abrupt ramps and the terrain delivering moments of separation as the field stretches and tightens through the Pyrenees. Expect positioning to rule and early accelerations that can fracture the peloton before the long finish to Peyragudes.
After about 50 kilometers of steady riding, the day becomes a mosaic of climbs and descents with no relief in sight. Every rise serves a purpose, every descent offers a brief recovery before the next gradient demands more. Buildup matters here, as riders balance the need to cover the early kilometers with conserving energy for the decisive ramps late on.
The opening obstacle is the Aspin climb, a 12-kilometer test at roughly 6.5 percent. This first port acts as a filter, helping teams shape the composition of the day. The second port, Hourquette d’Ancizan, is less steep but still capable of shuffling the field, echoing its historical role as a platform for early moves and for revealing who is truly ready to endure the Pyrenean grind. The aim is not a full blown attack but a calculated effort to thin the group for the later segments.
A springboard appears a bit later, just after the 30-kilometer mark. The Val-Louron ascent is irregular, spanning about 10.7 kilometers with a rough surface and a persistent 6.8 percent gradient. This climb tests the balance between power and technique. Riders must hold a steady tempo to avoid a blow up, while staying alert to any real moves that could split the bunch. The scenery adds drama as the road winds through the valley and crowds line the slopes, waiting for a pivotal moment in the race.
The summit of Val-Louron sits roughly 20 kilometers from the finish, followed by a swift descent toward the base of the next climb. From there the route heads toward the third Pyrenean checkpoint of the season, a stage where Megève and Mende have already left their marks. With the road turning uphill again, teams brace for a decisive push as the finish approaches.
Here the race will likely encounter an 8-kilometer ascent at about 7.8 percent, a longer, more sustained climb than in recent years. This is a true test of endurance and tactics; the longer climb echoes a memory from 2017 when a French rider prevailed, adding a layer of tactical memory for the current riders. The difficulty of this segment means gaps can widen, reshaping the GC and creating opportunities for bold moves from contenders who ride with precision and patience.
The Pyrenees in this stretch do not reach the extreme altitudes of the Alps, but the terrain remains capable of making a difference. The roads, while not towering, offer long rhythmic climbs and short sharp sections that favor riders who can sustain a strong rhythm and stay mentally focused from start to finish. The layout encourages a booted chase, with teams seeking chances to split the field and test rivals’ resolve.
It is plausible that a determined attacker could break away to contest the stage win, while those pursuing the GC might run parallel plans, conserving energy at the front while watching for weaknesses in others. The dynamics of this stage reward patience and the ability to strike at the right moment. Seize the opportunity and a rider can ride away; hesitate and the field can reel you back before the final ramp.
Stage 17: Saint-Gaudens – Peyragudes, 129.7 kilometers
Departure time: 13:25
Estimated arrival time: 17:00
Mountain profile highlights:
Col d’Aspin (1st): 12 km at 6.5%, 64 km remaining
Hourquette d’Ancizan (2nd): 8.2 km, 5.1% at 48.1 km
Col de Val Louron-Azet (1st): 6.8% to 10.7 km at 20.2 km

The day’s rhythm is defined by a clear line of climbs with varied profiles. The opening kilometers demand steady legs and smart positioning. Aspin and Hourquette d’Ancizan invite the stronger climbers to show themselves, while Val-Louron introduces a sharper rhythm capable of fracturing the peloton. The final climb to Peyragudes, with its persistent gradient, becomes the ultimate decider where the strongest riders prevail or a timely attack can rewrite the stage result. The route rewards those who navigate the day with composure and seize opportunities as they arise, delivering a race that blends endurance, strategy, and the enduring thrill of Pyrenean climbing.
