Lionel Sanders will take on Norwegian stars Kristian Blummenfelt and Gustav Iden at Challenge Xiamen this weekend, with the trio headlining the middle-distance race in China.

The Canadian has usually struggled to match the duo but has beaten both men before, most recently when winning IRONMAN 70.3 Oceanside in 2025. And their latest meeting provides an intriguing late-season contest on Saturday November 7.

Blummenfelt and Iden arrive after a trip to Taiwan which included a surprise appearance at an age-group IRONMAN 70.3 event, while Sanders will be looking to round out an injury-disrupted campaign on a positive note.

There is also a returning champion in each field, with Australia’s Kieran Storch defending the men’s title and Spain’s Sara Perez Sala bidding for another women’s victory.

Challenge Xiamen date and start times

The professional races at Challenge Xiamen take place on Saturday November 7, with the men starting at 0700 local time and the women following five minutes later.

For UK followers, that means 2300 GMT on Friday November 6 for the men and 2305 GMT for the women.

In North America, both races also start on Friday November 6: 1800 Eastern / 1700 Central / 1600 Mountain / 1500 Pacific for the men, with the women starting five minutes later.

Challenge Xiamen course

The race takes place beside Tongan Bay on Xiamen’s Huandong Romantic Coastal Line.

Athletes begin with a two-lap, 1.9km ocean swim from the beach at Meifeng Sports Park before tackling three laps of the coastal bike course for a total of 90km.

The concluding 21.1km run consists of four laps along the purpose-built coastal running path.

Men’s race: Sanders takes on the Norwegians

Blummenfelt’s season already includes victories at IRONMAN 70.3 Geelong, IRONMAN 70.3 Oceanside and IRONMAN Texas, alongside runner-up finishes at Challenge Roth and the IRONMAN 70.3 World Championship in Nice.

He finished eighth at the IRONMAN World Championship in Kona, where compatriot Iden claimed second.

Iden, meanwhile, brings a strong set of championship performances of his own, having finished fourth in Nice before his runner-up spot in Kona. He was also second at IRONMAN Frankfurt earlier in the season.

The pair have since been spending time in Taiwan, where they made a surprise appearance at IRONMAN 70.3 Kenting, not surprisingly topping the standings in what was an age-group event.

Sanders now provides a different challenge as the trio head to China.

The Canadian has raced sparingly during a season affected by injury, but remains the most compelling challenger to the Norwegian pair.

However he revealed last week that illness had interrupted his preparations again. “Just when I get in a decent groove, the sickness luck strikes again,” he wrote on Instagram, describing it as his eighth bout of illness in 10 months.

Their head-to-head records strongly favour Blummenfelt and Iden, who lead Sanders 6–2 and 5–2 respectively in individual races.

However, Sanders has an encouraging recent reference point: he beat both men to win at Oceanside in 2025, their most recent shared middle-distance race.

Blummenfelt was 15th that day and Iden third, although both subsequently finished well ahead of Sanders at IRONMAN Texas earlier this year.

Beyond those three big guns, New Zealand’s Mike Phillips and defending champion Storch are among the names to watch. Ognjen Stojanovic, Louis Woodgate, Antony Costes and Thomas Navarro are also on the start list.

Women’s race: Perez Sala returns to defend

Sara Perez Sala heads the women’s field as she returns to defend her Challenge Xiamen title.

The Spaniard’s season has included three T100 appearances and a third-place finish at Challenge Samarkand.

France’s Justine Guerard looks her principal challenger, arriving after finishing third at Challenge Forte Village. She also claimed second at Challenge Kaiserwinkl-Walchsee earlier in the year.

Australia’s Jasmine Brown and Paige Cranage, along with South Africa’s Magda Niewoudt, are among the other contenders.
