The world’s best middle-distance triathletes descend on the French Riviera this weekend as Nice hosts a mouthwatering women’s IRONMAN 70.3 World Championship.
And while defending champion Lucy Charles-Barclay will not be there after her late decision to focus fully on the IRONMAN World Championship in Kona four weeks later, there is no shortage of star power.
Three-time champion Taylor Knibb returns looking to regain the title she surrendered to Charles-Barclay in Marbella last year, while Britain’s Kat Matthews, reigning IRONMAN World Champion Solveig Løvseth and Laura Philipp headline a formidable list of challengers.
Add Olympic silver medallist Julie Derron, hometown favourite Marjolaine Pierré and a host of other big names into the equation and the battle for the 20th women’s IRONMAN 70.3 World Championship crown promises to be a fascinating one.
And there is another intriguing subplot.
For many of the leading contenders, Nice is not the ultimate target of the season. That comes four weeks later in Kona, creating a delicate balancing act between chasing a world title on the Côte d’Azur and ensuring they are ready to do it all again over twice the distance in Hawaii.
Here’s everything you need to know about the women’s race at the 2026 Precision Fuel & Hydration IRONMAN 70.3 World Championship.
Date, start time and how to watch
The professional women race in Nice on Saturday September 12, 2026, with the professional men taking centre stage 24 hours later.

Knibb the big favourite
There is nowhere more logical to start than Taylor Knibb.
The American has put together a phenomenal record at this championship since making her debut in 2021.
She finished third behind Lucy Charles-Barclay and Jeanni Metzler in St George that year before beginning an extraordinary run of three successive victories.
Knibb won in St George in 2022, successfully defended her crown in Lahti in 2023 and completed the hat-trick in Taupō in 2024.
Her 3:53:02 winning time in Finland remains the fastest ever recorded by a woman at the IRONMAN 70.3 World Championship.
The sequence finally ended in Marbella last November, but even then Knibb finished second as Charles-Barclay produced a superb performance to regain the title.
That makes Knibb the obvious benchmark in Nice, but this could be a very different challenge to some of those she has dominated in the past.
The American’s ability to put huge amounts of time into her rivals on the bike has been one of the defining features of her middle-distance success. Nice features a demanding 90km route through the Alpes-Maritimes rather than a straightforward power course but Knibb will surely be in prime bike form given that she is heading to the UCI World TT Championships a week later.
She will be expected to be at or near the front of the swim and hugely influential on the bike, but descending and bike handling could all play a major part in determining just how much separation she can create.
And if some of the world’s fastest runners are still within touching distance when they return to the Promenade des Anglais, the race could be far from over.
Can Matthews finally go one better?
If there is one athlete with unfinished business at the IRONMAN 70.3 World Championship, it is surely Kat Matthews.
The British star has finished runner-up at this race three times but is still searching for that elusive victory.
And 2025 provided another painful chapter.
Matthews was right in contention in Marbella before injury forced her out of the race, ending her hopes of finally reaching the top step.
Her 2026 campaign started superbly.
Matthews won IRONMAN New Zealand before victories at IRONMAN 70.3 Geelong and IRONMAN 70.3 Elsinore underlined once again why she is among the most consistent long-course athletes in the world.
But her last appearance came at Challenge Roth on July 5 and provided a rare disappointing day.
She has not raced in the more than two months since, meaning Nice will provide our first indication of how Matthews is shaping up ahead of the decisive part of her season.
There should be little doubt about her running ability if she can stay close enough through the swim and bike.
And given everything that has happened at this championship before, a first victory would be particularly significant.
Philipp hitting form at exactly the right time
Laura Philipp‘s season has followed a very different pattern to that of Matthews.
The German’s season was disrupted earlier in the year, but she has thrust herself firmly back into the picture during the last few weeks.
Philipp won IRONMAN Kalmar in Sweden in mid-August before making the rapid turnaround to IRONMAN 70.3 Zell am See-Kaprun just 15 days later.
She won there too.
It was an especially encouraging performance given that Philipp was right at the sharp end from the swim before stamping her authority on the race.
It means she heads to Nice with two victories in quick succession and potentially much more race sharpness than some of her biggest rivals.
Philipp also has plenty at stake beyond the World Championship title itself.
She leads the 2026 IRONMAN Pro Series standings on 14,663 points and Nice, as the penultimate race of the campaign, offers an enhanced maximum score of 3,000 points.
And, just like her main rivals, everything has to be viewed with Kona looming on October 10.
Nice is a huge target. But the biggest one is still to come.
Løvseth ready to pick up where she left off?
Few athletes have made a more dramatic impact on long-course triathlon over the last 18 months than Solveig Løvseth.
The Norwegian arrives in France as the reigning IRONMAN World Champion after her stunning victory in Kona last year.
And she already knows what it takes to beat Philipp over the full distance this season.
Løvseth won IRONMAN Hamburg on June 7, producing the fastest bike split before holding off the German by just 1:18.
She hasn’t raced since which means Løvseth will arrive at the 70.3 World Championship after more than three months without competition – an entirely different route to Nice from the one taken by Philipp.
It also makes her one of the hardest athletes to assess.
She should be exceptionally fresh but will she be race sharp enough to immediately take on Knibb, Matthews and Philipp over the much faster 70.3 format – and how will the hilly Nice bike course suit her?
Four favourites – four very different routes to Nice
That contrast in preparation could be one of the most fascinating aspects of Saturday’s race.
Matthews hasn’t competed since Roth on July 5.
Løvseth hasn’t raced since Hamburg almost a month earlier.
Philipp, meanwhile, has raced and won an IRONMAN and a 70.3 in the space of little more than two weeks.
Knibb has been sharpening her speed against the world’s best short-course athletes and will switch sports altogether just eight days after Nice.
And hanging over all of them is Kona.
Charles-Barclay’s absence emphasises the balancing act better than anything else.
The defending 70.3 World Champion had initially been set to race but ultimately decided that tapering for Nice, travelling, racing and then recovering would take too much away from the final preparation for her bid to regain the IRONMAN World Championship crown.
Her biggest rivals have made a different choice.
By Saturday afternoon we’ll know who got the Nice part of the equation right. The full answer may not arrive until Hawaii four weeks later.
Best of the rest
The leading quartet certainly don’t have the race to themselves.
Julie Derron is arguably the most intriguing threat from outside that group.
The Swiss star won Olympic silver behind Cassandre Beaugrand in Paris in 2024 and possesses the sort of speed that makes the prospect of her reaching T2 alongside the leaders particularly dangerous.
Then there is Marjolaine Pierré.
The Frenchwoman doesn’t merely have home-country advantage – she is from Nice and knows the roads incredibly well.
She has already demonstrated her credentials on demanding terrain this season with victory at IRONMAN 70.3 Aix-en-Provence.
No French athlete has ever won the professional women’s IRONMAN 70.3 World Championship.
What a place this would be to become the first.
The depth extends considerably further.
Switzerland’s Alanis Siffert continues to establish herself among the leading names in middle- and long-distance racing and could be particularly well suited to a challenging bike course.
And one key point to note with her is that she is swerving Kona this year so this is the biggest race left in what has been a breakthrough campaign.
She will almost certainly need a decent lead from the top runners after the bike though if she is going to prevail.
Paula Findlay brings enormous experience and was one of the athletes who raced when the 70.3 World Championship was last held in Nice in 2019.
So too did Australia’s Ellie Salthouse, whose extraordinary consistency at this distance has produced 19 professional IRONMAN 70.3 victories dating back to 2016.
A course worthy of a World Championship
Nice provides one of the most distinctive courses in long-distance triathlon.
The race begins with a single-loop 1.9km swim in the Mediterranean Sea (which will be non-wetsuit), with athletes entering and exiting at Plage des Ponchettes before swimming towards the city’s famous ‘I LOVE NICE’ sign. It can be choppy but equally could be pretty calm depending on conditions.
Then comes what is likely to be the decisive section.
The 90km single-loop bike course heads away from the Mediterranean and into the Alpes-Maritimes.
The headline challenge is the long ascent of the Col de Vence, but this isn’t simply about climbing. The twisting roads and subsequent return towards Nice will put a premium on descending skills, positioning and confidence as well as pure power.
That could have major implications for a women’s race containing athletes with very different strengths.
Knibb will surely want to turn the screw on the bike, but Matthews, Philipp and Løvseth are all exceptional cyclists themselves, while the terrain potentially offers opportunities to limit the American’s usual advantage.
Then everything changes again.
The 21.1km run consists of two loops along the famous Promenade des Anglais.
After the climbing and technical demands of the bike, the flat and fast run should favour the pure runners – which could make the gaps at T2 absolutely crucial – they could be huge.
How much time does Knibb need?
How close do Matthews, Philipp, Løvseth and particularly Derron need to be? Is Siffert the wildcard?
Those questions could define the race.
Nice and the 70.3 Worlds
The IRONMAN 70.3 World Championship celebrates its 20th anniversary in 2026.
The inaugural race was staged in Clearwater, Florida in 2006 and remained in the United States until the championship began rotating internationally in 2014.
Nice first hosted the event in 2019 when Daniela Ryf produced a typically commanding display, winning in 4:23:04 ahead of Holly Lawrence, with Imogen Simmonds completing the podium.
The Côte d’Azur has since become even more deeply intertwined with the sport, hosting IRONMAN World Championship racing in 2023, 2024 and 2025.
And some of this year’s contenders have previous 70.3 Worlds experience here too, including Matthews, Findlay and Salthouse.
IRONMAN Pro Series – what’s at stake?
There is considerably more than a world title and prize money on offer in Nice.
The race is the penultimate event in the 2026 IRONMAN Pro Series and, as a World Championship, offers more points than a standard IRONMAN 70.3.
The winner receives a maximum 3,000 points, 500 more than at the other 70.3 races in the Series.
Seven of the current women’s top 10 are due to race.
Philipp leads the standings with 14,663 points, while Løvseth is fifth on 12,385 despite having completed only three scoring races.
That latter detail is significant because Løvseth can add her entire Nice score to her existing total, potentially transforming the standings before the final showdown at the IRONMAN World Championship.
With a $1.7million year-end Pro Series bonus pool also on the line, every second in Nice could ultimately prove very valuable.
IRONMAN 70.3 World Championship prize money
The professional athletes will also be competing for a $500,000 prize purse, unchanged from the 2025 championship, with the winners taking home $75,000 each for their efforts.
The prize breakdown is as follows:
- 1. $75,000
- 2. $45,000
- 3. $30,000
- 4. $19,000
- 5. $15,000
- 6. $12,000
- 7. $10,000
- 8. $8,000
- 9. $7,500
- 10. $7,000
- 11. $6,000
- 12. $5,000
- 13. $4,000
- 14. $3,500
- 15. $3,000
