2026 TDS Results: France Sweeps, Sarah Vieuille and Remy Brassac Win

The post 2026 TDS Results: France Sweeps, Sarah Vieuille and Remy Brassac Win appeared first on iRunFar.

The UTMB Mont Blanc festival is the year’s biggest week of ultrarunning! It started on Monday, August 24 and goes all week, and TDS marked the competitive start of the ultra distances.

OCC, CCC, and UTMB are the week’s UTMB World Series Finals, and so TDS is less competitive than those races, but it is regarded as one of the week’s most technical and challenging races. A year ago, weather impacted the traditional course. There was overnight rain this year too, but the course was back to a 148-kilometer race from Courmayeur, Italy to Chamonix, France on a clockwise direction that totaled 9,300 meters of climbing. That’s almost 92 miles and with 30,500 feet of elevation gain.

The race name is an acronym for Sur les Traces des Ducs de Savoie, which translates as “following the footprints of the Dukes of Savoie.” It celebrates a historical mountain route while going point-to-point between two countries. The challenge started at night at 11:50 p.m. local time on Monday, August 24.

French runners Sarah Vieuille and Remy Brassac won in 22:08 and 19:28. Vieuille led all of the women’s race and held off Alice Meignié, also from France, over the race’s second half. Pre-race women’s favorites Anna Tarasova and Ida-Sophie Hegemann from Spain and Germany did not finish. Brassac went to the front of the men’s race early with Louison Coiffet and Clovis Chaverot. Both Coiffet and Chaverot dropped and Brassac overcame the chase field and the mountain course to score victory.

2026 TDS Women’s Race

The climbing started right away and was punctuated by cold nighttime rain and fog. Runners ascended to the 8,540-foot course high point at Col Chavannes at mile 13 and Sarah Vieuille (France) and Anna Tarasova (Spain) were already five minutes in front of third-place Alice Meignié (France). Tarasova was third at CCC in 2025 and was the top-ranked, by UTMB Index, woman in this year’s TDS field. Vieuille and Tarasova split 2:40 to the Col Chavannes timing mark, and Meignié and fourth-place Ida-Sophie Hegemann (Germany) arrived in 2:45 and 2:47. Hegemann was seeking TDS redemption after dropping at last year’s race.

Most of the next 19 miles ran downhill to mile 32 in Bourg Saint-Maurice with only a 1,300-foot climb to La Thuile at mile 22 to break up that long descent. In the 10 miles from Col Chavannes to La Thuile, Viulle had made an early break. She split 4:25 to La Thuille and that was almost nine minutes faster than second-place Tarasova. Meignié and Hegemann were still third and fourth, minutes behind Tarasaova. This was Vieuille’s first race in Chamonix, but she was very familiar with difficult courses after a 2025 Diagonale des Fous fourth-place finish.

After a nearly five-minute stop, Vieuille exited Bourg Saint-Maurice (mile 32) in 5:55, having completed that big 19-mile mostly downhill stretch coming off the course high point at Col Chavannes. Hegemann had vaulted into second with Tarasova and Meignié third and fourth and all within two minutes of each other. The chase three were all about 10 minutes behind Vieuille.

The next seven miles had a massive 5,600-foot climb to Passeur de Pralognan at mile 38. This climb and the next section are perhaps the race’s most challenging. After Passeur de Pralognan, there’s 19 miles of course through the Beaufortain Massif with technical, high-alpine terrain, and a long descent into Beaufort at mile 57. It’s a wild, middle crux of the race with the potential to shake up the leaderboard.

Vieulle was 21 minutes ahead of Meignié and Hegemann at mile 38 Passeur de Pralognan, but Tarasova was now back to fourth and another 11 minutes behind the second- and third-place women.

And then at the critical mile 57 Beaufort checkpoint, having come off that descent, Vieuille was still in the lead in 12:28 elapsed. That was 39 minutes faster than second-place Meignié. Alyssa Clark (U.S.) had mastered the high terrain challenge and moved into third place. Clark had taken on the full UTMB loop each of the last two years, finishing 11th in 2024. After falling outside the top 10, Tarasova dropped here at mile 57 and further up trail, just like in 2025, Hegemann’s race stopped at mile 62 in Hauteluce with a drop.

Vieuille continued to lead the race through the next series of climbs, but Meignié was making up time. A 39-minute gap at mile 57 was down to just 25 minutes at mile 72. Clark, meanwhile, was only 22 minutes behind Meignié going into the race’s late stage. And then at mile 80 Col de Tricot, Vieulle’s lead was only 19 minutes.

Meignié got no closer though and those three stayed first, second, and third the rest of the way.

Sarah Vieuille won the 2026 TDS in 22:08. She led for all of the race and finished ninth overall too. She wasn’t too far back of Audrey Tanguy’s longstanding 21:36 course record from 2019. For greater time perspective, Marie Dohin’s 2024 winning time on this same course was 24:06 and Careth Arnold won last year’s rerouted race in 22:58.

Alice Meignié finished as runner-up in 22:30, and Alyssa Clark was third in 22:54.

2026 TDS Men’s Race

A three-man French group of Clovis Chaverot, Louison Coiffet, and Remy Brassac were together at mile 10 on the way to the course high point, but by mile 13, Coiffet had earned a five-minute lead on his chasers. In the dark and in cold rain, Coiffet was at the mile 13 Col Chavannes course high point in 2:20. Joël Dumas (Switzerland) was in fourth another four minutes behind Chaverot and Brassac, and Tyler Green (U.S.) moved across the top in fifth place. Coiffet won the Marathon du Mont Blanc 90k, also in Chamonix in June 2026, and was the race’s top-ranked runner by UTMB Index. Green, the second-ranked man, was returning to TDS after a 10th-place finish in 2021.

Coming off the high point, Chaverot and Brassac regained Coiffet. By the time they dropped down and then climbed 1,300 feet partially back up to mile 22 at La Thuile, the three were within a minute of each other at the front of the race. Green had overtaken Dumas for fourth, but was still about six minutes behind the leading trio. It was Chaverot’s longest race to date. He’d twice finished CCC before with his best a 22nd-place finish in 2022.

There’s a big descent from mile 22 in La Thuile to mile 32 in Bourg Saint-Maurice and Coiffet exited the race here while positioned in fourth behind Chaverot, Brassac, and Green. The next section climbs steeply for 5,600 feet from mile 32 in Bourg Saint-Maurice to mile 38 at Passeur de Pralognan, runs across a remote high-alpine section, and then plunges downhill into mile 57 in Beaufort. It’s a challenging section that, as the sun came up, would further break up the leaderboard.

Chaverot and Brassac were together at the mile 38 Passeur de Pralognan summit, but by mile 57 Beaufort, Chaverot led his countryman challenger by 13 minutes. Green made time up on the leaders on the climb, but hit trouble on the descent and dropped from the race at mile 57 in Beaufort. Roald Froskeland (Norway) vaulted into third place with about 36 miles to go. Pierre-Adrien Hivert (France) and Davide Rivero (Italy) were only minutes behind Froskeland and just outside the third podium position. Early frontrunner Dumas dropped at mile 57 in Beaufort, too.

Exiting Beaufort, the race again climbed roughly over the next 13 miles. By the time they started the descent at mile 71, Chaverot was back to third. Brassac and Hivert had both passed longtime leader Chaverot. The two reached the mile 72 checkpoint first and second, but with Brassac 24 minutes ahead of Hivert. Chaverot reached mile 72 in third, but dropped from the race there after having led most of the first 67 miles. Rivero moved from fourth onto the podium in third at this moment.

Those three carried their podium positions to the finish with the gap between each growing over the remaining distance.

France’s Remy Brassac won the 2026 TDS in 19:28. Of the early leading three, Brassac was the only one to finish. In early July, Brassac was fourth at the Val d’Aran 110k. For historical perspective, Thibault Marquet won the 2024 race on this course in 18:59 and Antoine Charvolin won last year’s weather-impacted race in 18:22.

Also from France, Pierre-Adrien Hivert was second in 20:14. That was a big step up from his ninth-place finish at last year’s TDS.

Italy’s Davide Rivero was third in 20:42. Rivero was the only non-French finisher inside the men’s top 10.
