Flash News: Leeds Algae Scare, Kalmar Records, Polish Titles
The last full-distance Kona-qualifying race of the season turned into a German show of strength. A record fell along the way that will be talked about until October. Białystok, Poland crowned new Polish champions, and in Leeds, cyanobacteria took swimming off the table. Triathlon started a serious conversation about what temperature should be allowed to hold a race at all.
1. Kalmar: Schomburg and Philipp break the bank before Kona
On Saturday 15 August, Sweden delivered a German double. Jonas Schomburg won his first professional IRONMAN title in 7:22:57, improving the course record by almost 16 minutes. In the women’s race, Laura Philipp had no rivals of her own and finished in 8:13:37, more than 14 minutes under the previous record.
One thing is worth watching here. Schomburg’s time sits under two minutes off Sam Laidlow’s 7:21:04 at Challenge Roth, the fastest long-distance result in history. The record within a race carrying the IRONMAN brand, however, is Kristian Blummenfelt’s 7:21:24 from Texas. So these are two different numbers in two different categories.
The full results, splits and the Kona slot breakdown from Kalmar are covered in more detail elsewhere.
2. Kallin rode 180 km in 3:53:12 and still missed his ticket
It was also the fastest bike split in IRONMAN history. Sweden’s Robert Kallin stopped the clock at 3:53:12, 20 seconds inside Cameron Wurf’s record. Schomburg caught him around the 10th kilometre of the marathon, seemingly without effort, and Kallin ended the day without a ticket to Hawaii.
This is the best free pacing lesson available. The bike leg wins headlines, but the marathon wins the race. If a brick session regularly leaves your legs numb when you dismount, that is not a sign of a strong ride. It is a sign you have blown the budget.
3. Białystok crowns Polish champions: Kulik and Woźniak on top
On Sunday 16 August, the twelfth edition of the Elemental Tri Series took place at Zalew Dojlidy in Białystok, Poland, this year carrying Elite/Open and U23 Polish Championship status over the standard distance. Kamil Kulik took the men’s title in 1:49:22, edging out Kuba Gajda (1:49:36) by just 14 seconds and Jan Chmielewski (1:50:31). In the women’s race, Joanna Woźniak was fastest in 1:59:32, ahead of sisters Zuzanna Sudak (2:00:24) and Magdalena Sudak (2:01:45).
Kulik also added the U23 title, and Józefina Młynarska was fastest among the younger women. Nearly 450 athletes raced in Białystok, with about 90 children taking part in accompanying kids’ races. The event also included the Polish Paratriathlon Championship, the Polish Integration Relay Championship and the Polish Age Group Aquabike Championship. Draft-legal riding was allowed on the elite bike leg, so power and tactics decided the medals.
4. Derron back on top: T100 Vancouver for the Swiss
Paris Olympic silver medallist Julie Derron picked up her first big win of the season, taking T100 Vancouver in 3:33:26. The Swiss athlete caught T100 world champion Kate Waugh on the run and held on for a 1:40 margin, posting the field’s fastest 18 km split at 1:04:19. Georgia Taylor-Brown finished third, 3:02 back, which ended her hopes of a double after her win in Spain.
The women’s race took place on Saturday 15 August around Locarno Beach, with age-groupers racing the same course on Sunday. The broadcast was free on TriathlonLive.tv, in line with the PTO’s promise of free access to the entire T100 season.
5. Leeds without swimming: cyanobacteria turn IRONMAN into a duathlon
The second edition of IRONMAN Leeds was meant to be a celebration; instead it turned into a row. The day before the race, organisers cancelled the swim in Waterloo Lake after testing showed cyanobacteria concentrations well above the safety threshold. About 2,500 athletes started a duathlon instead: 180 km bike and 42.2 km run.
The anger was not really about the decision itself, since most people considered it the right call, but about how it was communicated. The wider cyanobacteria story, and how to check a swim venue’s status before your own race, is covered in more detail elsewhere.
6. How many degrees is too many? Triathlon starts talking about hard limits
This summer left clear marks on the European calendar. IRONMAN cancelled both races in Nice, full distance and 70.3. It also shortened the bike and run legs in Frankfurt, and pushed the Versailles debut back to 11 October. Next year’s Nice race will move to September. In both French cases, the decision was forced by local authorities worried about the capacity of emergency services.
The trouble is that the sport has no official temperature threshold. World Triathlon runs a “Beat the Heat” programme based on the WBGT index, which combines air temperature, humidity, solar radiation and wind. The scale has five levels: green below 25.7°C (78.3°F), blue 25.7 to 27.8°C (78.3 to 82.0°F), orange 27.9 to 30°C (82.2 to 86°F), red 30.1 to 32.2°C (86.2 to 90°F) and black above 32.2°C (90°F). It remains guidance rather than a rule, and the final call still belongs to the race director. In a Daily Split newsletter survey, 82 percent of readers backed mandatory thresholds. For an age-grouper planning a July start, the practical takeaway is to check the WBGT forecast, not just the air temperature.
7. Supertri hands out $800,000, and Yee meets Wilde
On 6 September, Jersey hosts the Supertri Pro Series final, with an $800,000 purse, the largest single-day payout in this year’s triathlon. On the start list: Olympic champion Alex Yee, Olympic silver medallist Hayden Wilde and defending world champion Matt Hauser. It is a rematch of the rivalry that has defined short-course racing since Paris.
In the women’s race, Olympic champion Cassandre Beaugrand faces Georgia Taylor-Brown, defending Supertri champion Jeanne Lehair and former European champion Jolien Vermeylen. The Supertri format runs three rounds of swim, bike and run back to back, so the race is worth watching even for someone who has never raced short course.
8. IRONMAN aims for a 50/50 gender split at Bolton
IRONMAN officially backed ForTheGirls, a grassroots campaign founded by two age-group athletes from the north of England. The goal is specific: 50/50 women and men on the start line at IRONMAN 70.3 Bolton in 2027.
The numbers are already moving the right way: 2025 data showed a 9 percent rise in women’s registrations across the whole IRONMAN portfolio. The full story, including what the organiser has already introduced, is covered in more detail elsewhere.
9. August firmware without fireworks
Anyone waiting on new watch features can stop waiting. In the week to 15 August, Garmin, COROS, Suunto, Polar and Wahoo released stability fixes only. Updates went out for the Fenix 8, Forerunner 970 and 570, Venu 4, vivoactive 6, and the Edge 550, 850 and 1050 computers. The changelogs were mostly device resets, radar pairing and translation corrections. Only Amazfit added real functionality: a manual pause for pool swimming, FTMS-standard rowing machine support, and a screen lock during workouts.
Kallin’s record will be remembered longer than his final result. Philipp, meanwhile, heads to Kona in the kind of form nobody wants lined up next to them on the course. At home, Poland has new champions in Kulik and Woźniak. The Leeds situation leaves one question open that will come back again: nobody has settled how much of the entry fee an organiser should refund when it cancels the swim the day before the race.
