The Tour de Suisse Women 2026 begins on Wednesday, 17th June, with a stage that immediately sets the tone for the new five-day format. Stage 1 starts and finishes in Sondrio, in Italy’s Valtellina region, over 109.3km and 1,642m of climbing. It is not a gentle roll-out, not a parade for the sprinters, and not the kind of opener where the general classification contenders can hide for a day.
The official route gives the opening stage a hilly 4/5 difficulty rating, and the finale includes two short but steep climbs that should make a conventional bunch sprint unlikely. That makes Sondrio a proper first test for the Tour de Suisse Women 2026, especially with a compact race structure that leaves little room for a slow build-up.
The five-day race moves from Sondrio to Locarno, Bad Ragaz, Aarburg and Villars-sur-Ollon, with a 23.8km individual time trial on stage 4 and a mountain stage on stage 5. The overall contenders do not need to win on stage 1, but they cannot afford to lose concentration. A small split, a missed move or a poor descent could already shape the race before it even reaches Switzerland.

Tour de Suisse Women 2026 stage 1 route
Stage 1 takes place in and around Sondrio, a town set in the Valtellina valley and surrounded by terraced vineyards, alpine roads and the kind of mid-altitude terrain that makes rhythm difficult. The stage is officially 109.3km with 1,642m of elevation gain, and while that is not a mountain stage by Tour de Suisse standards, it is a hard opener.
The stage begins with a flatter section before the route turns into repeated climbing and descending. The first hour may be relatively controlled, but the race should become more selective once the terrain starts to rise and fall more regularly. It is not simply one decisive climb followed by a run-in. It is a stage where fatigue can build through constant changes of gradient.
The official description compares the character of the day less to flat Classics and more to races such as Il Lombardia. That is the right way to think about it. Stage 1 is not about high-altitude climbing or long Alpine passes. It is about hilly roads, repeated accelerations, technical positioning and a finale that should reward riders who can climb sharply and still sprint from a reduced group.
The two steep climbs in the finale are the key. They should give attackers and GC riders the chance to test the peloton, while making it difficult for pure sprinters to survive. If the front group is small enough after those climbs, the opening yellow jersey could go to a climber, a punchy all-rounder or a classics-style rider rather than a fast finisher.
Why stage 1 matters for the GC
The Tour de Suisse Women 2026 route gives the GC contenders three obvious checkpoints: the hilly opening stage in Sondrio, the time trial in Aarburg and the final mountain stage in Villars-sur-Ollon. Stage 1 may not decide the whole race, but it can immediately remove riders from contention.
That is the danger of the new format. In a longer stage race, a rider can lose 20 or 30 seconds on the opening day and still have several mountain stages to recover. Here, the race is only five days long. The time trial will create gaps, the final mountain stage will create gaps, and every bonus second or small split before then becomes more valuable.
The best GC riders will want to stay near the front through the final 30km. The stage is unlikely to reward a team that tries to ride passively and rescue the situation late. If the final climbs are ridden hard, the peloton should fracture before the finish. Anyone caught behind a split will have little time to recover, especially with stage 2 in Locarno also offering punchy terrain rather than an easy reset.
For Demi Vollering, Marlen Reusser, Kasia Niewiadoma-Phinney, Elisa Longo Borghini, Lotte Kopecky, Antonia Niedermaier and the rest of the overall contenders, the first task is simple: avoid losing the race before the more obvious GC days arrive.

Stage 1 looks best suited to a punchy climber or classics-style all-rounder. The winner will need to survive the repeated climbing, stay positioned through the finale and still have a finish after a hard day.
A pure sprinter will struggle unless the pace is surprisingly controlled. The route does not look selective enough for a pure climber to be the only type of contender, but the steep late climbs should thin the group enough to make the sprint very different from a flat bunch finish.
That points towards riders who can climb at threshold, follow attacks over short steep sections and then sprint from a reduced group. It also creates room for a solo move if the favourites hesitate. With several GC teams likely to be nervous about losing time, the final could become tactical. If the strongest riders mark each other, an aggressive rider could slip clear on one of the steep late ramps and hold on.
The stage also suits teams with multiple options. Kopecky can be a threat if the group is reduced but not destroyed. Niewiadoma-Phinney can attack and still finish well from a small group. Reusser can use power and timing if the finale becomes less explosive and more attritional. Vollering can win from a GC selection if the race becomes hard enough.
Demi Vollering – FDJ United-SUEZ
Demi Vollering starts the race as the clear GC benchmark after winning the Giro d’Italia Women, and Sondrio gives her an immediate chance to impose herself. She does not need to win stage 1, but she will want the race to be hard enough to keep the overall contenders in view and prevent opportunists from taking too much early time.
The stage suits her more than a pure sprint opener would. The repeated climbs, steep final ramps and reduced-group possibility all give Vollering terrain where she can ride aggressively without needing to commit to a long-distance move. If FDJ United-SUEZ decide to make the finale hard, she can follow the decisive move or force one herself.
The main question is how much energy she wants to spend on day one. With a time trial and queen stage still to come, Vollering may be content to stay safe and collect the first signs of form from her rivals. But if the race naturally breaks apart, she is one of the riders most likely to benefit.
Marlen Reusser – Movistar
Marlen Reusser gives the race one of its strongest storylines. She has already built serious Tour de Suisse history, and the 2026 route gives her several opportunities, especially with the Aarburg time trial still to come. Stage 1 is not her most obvious day on paper, but it should not be overlooked.
The hilly Sondrio circuit could suit Reusser if the racing becomes attritional rather than explosive. She is powerful enough to turn repeated climbs into a grinding selection, and if a small group forms with no one fully committed to chasing, she has the engine to make a late move dangerous.
Movistar also have Liane Lippert, which gives them a strong second option for exactly this kind of terrain. Lippert may be the more natural reduced-group finisher, while Reusser is the bigger GC and time-trial threat. That combination makes Movistar one of the teams that can shape stage 1 without needing to ride only for one outcome.
Lotte Kopecky – Team SD Worx-Protime
Lotte Kopecky may be one of the most dangerous riders on stage 1 if the race comes back together after the final climbs. The route is too hard for most pure sprinters, but not necessarily too hard for Kopecky if she is climbing well. That puts her in the ideal grey area between sprinter, classics rider and stage-race disruptor.
Team SD Worx-Protime are likely to enjoy the tactical uncertainty. If the finale is raced aggressively, Kopecky can follow the strongest moves. If the GC riders hesitate, she can use her strength and positioning to stay near the front. If a reduced group reaches the finish, she is one of the fastest riders who could realistically survive the selection.
Her stage-winning case depends on the climbs being hard, but not too hard. If Vollering or Niewiadoma-Phinney turn the final ramps into a pure climbing fight, Kopecky may have to limit losses. If the front group stays between 10 and 25 riders, she becomes one of the clearest favourites for the stage.
Kasia Niewiadoma-Phinney – Canyon SRAM
Kasia Niewiadoma-Phinney is a natural contender for a stage like this. The Sondrio route rewards repeated accelerations, technical confidence and the ability to race aggressively on terrain that is too hard for sprinters but not mountainous enough for pure climbers to dominate.
For Canyon SRAM, the stage offers both opportunity and responsibility. Niewiadoma-Phinney cannot afford to lose time before the race reaches the bigger GC days, but she also has the profile to gain time if others hesitate. A short, steep climb in the finale is exactly the kind of terrain where she can force a selection without needing a long solo move.
The question is whether she waits for the final climb or tries to make the race difficult earlier. If the final group is too large, Kopecky and other fast finishers become harder to beat. If Niewiadoma-Phinney can reduce the group before the final kilometres, she can turn the stage into something much more selective.

Elisa Longo Borghini comes into the race with a strong stage 1 case if she is carrying the form she showed late at the Giro d’Italia Women. The Sondrio opener has the right mix of climbing, technical roads and tactical pressure for a rider who has spent a career making hard days even harder.
This is not the type of stage where she needs a full mountain train. It is a day for awareness, timing and aggression. Longo Borghini can follow the best climbers, attack when the favourites look at each other, or sprint from a small group if the race is selective enough.
UAE Team ADQ also have recent confidence after Paula Blasi’s win at the Tour Féminin International des Pyrénées, although this race is a different level and a different kind of route. The team’s best stage 1 approach may be to keep Longo Borghini close to the front, let others take some responsibility, and use the late climbs to test who is already under pressure.
Liane Lippert – Movistar
Liane Lippert may be one of the best stage-specific options for Movistar. If Reusser is the broader GC and time-trial card, Lippert is the rider who looks particularly well suited to a reduced-group finish after steep late climbs.
Her strengths match the stage profile neatly. She can climb short, sharp gradients, handle technical finales and sprint well from a small group. That makes her dangerous if the GC favourites neutralise each other but do not fully control the race.
Movistar’s dual threat is important. Reusser can force other teams to think about the overall, while Lippert can focus on the stage-winning moment. If both are still in the front group after the final climb, Movistar may be one of the hardest teams to manage.
Antonia Niedermaier – Canyon SRAM
Antonia Niedermaier is one of the most interesting GC riders in the race after finishing second overall at the Giro d’Italia Women. Stage 1 may not be her ideal day in the way the final mountain stage will be, but it is still important for her overall ambitions.
The main objective is to stay safe, stay close and avoid being caught behind a late split. Niedermaier does not need to chase every punchy attack if Niewiadoma-Phinney is also in the front group for Canyon SRAM, but she cannot allow the race to become a classics-style fight happening just out of reach.
Her climbing strength should be enough to survive the harder sections, and if the final climbs are ridden more severely than expected, she may move from defensive GC rider into stage contender. The steeper the finale becomes, the better her chances of being part of the decisive selection.
Magdeleine Vallières – EF Education-Oatly
Magdeleine Vallières gives EF Education-Oatly a strong option for a stage where positioning and resilience may be as important as pure climbing numbers. As world champion, she will be easy to spot and closely watched, but the terrain gives her room to race positively.
The Sondrio opener should suit her if the stage becomes hard from distance. She is not a pure sprinter waiting for a flat finish, and she is not a rider who needs a long mountain to make an impact. Her best route may be through an aggressive final 20km, especially if the bigger GC favourites are more focused on each other.
EF Education-Oatly could also look to use numbers if the race becomes tactical. If Vallières reaches the final climbs in the right position, she has the strength to follow the front group and the confidence to make others chase.
Kim Le Court – AG Insurance-Soudal
Kim Le Court is a stage 1 danger because the route sits close to her best racing profile. She can handle hilly terrain, she can survive selective finales, and she has the kind of finish that becomes very useful if the group is reduced but not reduced enough for a pure climber to go clear.
AG Insurance-Soudal also have Justine Ghekiere and Urška Žigart for more climbing-heavy scenarios. That gives the team flexibility. If the stage becomes very hard, Ghekiere or Žigart may be better placed to follow the strongest climbers. If it becomes a reduced sprint, Le Court is the obvious name to watch.
The team’s tactical problem is choosing the right moment. Too much early commitment could leave them exposed if the GC teams take over. Too little could leave Le Court too far back before the steep climbs. If they get the positioning right, she is a realistic outside bet for the stage.
Other riders to watch
Sarah Van Dam could be interesting if the race becomes more open. She has the punch and racing instinct for hilly terrain, although the depth of the start list means she will need the right move rather than a straightforward head-to-head with the biggest favourites.
Valentina Cavallar and Nienke Vinke are more likely to matter if the stage becomes closer to a GC selection than a reduced sprint. Both have profiles that could handle a hard opener, and neither should be ignored if the pace over the final climbs becomes severe.
The opening day may also suit a breakaway if the GC teams hesitate. That looks less likely because the first leader’s jersey is at stake, but the terrain does give attackers room. A strong move with riders outside the main GC favourites could be awkward to control if several top teams decide they do not want to spend too much energy on day one.
Race tactics
The first half of the stage should be about control. Teams with GC riders will want to avoid early stress, while teams without overall ambitions may try to place riders in the breakaway. Because the stage is short, however, the peloton cannot allow a strong move too much freedom.
The race should sharpen once the route turns into the constant up-and-down section through the Valtellina. This is where positioning becomes more important. Even if the decisive moves do not happen immediately, teams will want their leaders near the front before the late climbs.
The final two steep climbs should decide the stage shape. If FDJ United-SUEZ, Movistar, Canyon SRAM or Team SD Worx-Protime ride hard, the group could shrink quickly. If the favourites watch each other, the door opens for a late attacker or a reduced-group sprint.
Bonus seconds also matter. In a race with a time trial and final mountain stage still to come, nobody will win the GC only because of stage 1 bonuses, but they could still change the race rhythm. Taking the first yellow jersey also brings control responsibilities, so some teams may want the stage without wanting to carry the race for four more days.
Prediction
The stage looks too hard for a full bunch sprint and not quite mountainous enough to guarantee a pure climber wins. That makes Kopecky a compelling pick if she survives the final climbs in a reduced group. She has the speed, strength and tactical sharpness to win from the kind of front selection this route seems likely to create.
Vollering is the safest GC-based pick. If the final climbs are ridden hard enough to reduce the race to the main favourites, she can win the stage and take yellow immediately. Reusser and Lippert give Movistar two realistic routes to victory, while Niewiadoma-Phinney and Longo Borghini are both capable of making the finale more aggressive.
The most likely pattern is a selective finish from a reduced group rather than a solo win. A late attack is possible, especially from Reusser, Niewiadoma-Phinney or Longo Borghini, but the first yellow jersey should come from the strongest group that survives Sondrio’s steep final climbs.
