Swimming-induced pulmonary oedema in triathletes: A narrative review of epidemiology, risk factors and prevention

Swimming-induced pulmonary oedema (SIPO) has predominantly been reported in swimmers. However, to date, no review has specifically explored the scientific literature concerning the occurrence and characteristics of SIPO in triathletes. Therefore, this review aims to summarize and discuss the current evidence on SIPO in the context of triathlon. We conducted a narrative review to summarize the current scientific literature on SIPO in triathletes. A structured search of two major databases—PubMed and Scopus—was conducted using free-text terms related to SIPO and triathlon. The search included articles published up to January 2025, with no language restrictions. After removing duplicates and excluding animal or in vitro studies, as well as unrelated articles based on title and abstract screening, a total of 48 relevant publications were included for analysis. The reports on SIPO in triathletes are mainly case reports or case studies on a single athlete or a small number (case series) of triathletes. Most reported cases involved middle-aged women (30 to 60 years) participating in IRONMAN® 70.3 and IRONMAN® triathlons. The prevalence of SIPO in triathletes is reported to be less than 1.5%. Risk factors for SIPO in triathletes are female sex, age over 50 years, hypertension, fish oil consumption, highly trained individuals, competitive exercise, wet suit compression, longer race distances (i.e. IRONMAN® 70.3 or IRONMAN®) and a cold (water) environment. The symptoms and outcome are similar to those observed in swimmers and other aquatic athletes. In summary, the results regarding the prevalence, symptoms and risk factors of SIPO in triathletes are comparable to those in other aquatic athletes. SIPO occurs only in IRONMAN® 70.3 and IRONMAN® races, but has not been reported in the Olympic distance triathlon or triathlons longer than the IRONMAN® race distance.

Schaffhauser Bock Marathon

Am Nationalfeiertag fand der Schaffhauser Bock Marathon von Schaffhausen nach Zurzach Bad statt. Auf teils recht schnellen Radwegen kamen wir trotz starkem Gegenwind recht gut voran.

Es ging auch recht flott dank des schönen Wetters und das es trotz vielen Hundert Höhenmetern eigentlich flussabwärts ging.

Zigerschlitz Marathon in Glarus

Den Abschluss der Sommermarathons bildete der ZigerschlitzMarathon vom 3. August in Glarus.

Viel Trail, viel Kies, viele Höhenmeter und beeindruckende Berge die wir hautnah sehen konnten.

Sex-specific differences in performance and pacing in the world’s longest triathlon in history

Sex differences in performance and pacing in triathlon have been studied for IRONMAN triathlons (3.8 km swimming, 180 km cycling and 42.195 km of running) and ultra-triathlons (i.e. Double-, Triple-, Quintuple- and Deca Iron ultra-triathlons) corresponding to 2x, 3x, 5x and 10x the IRONMAN triathlon distance. However, no study has to date investigated the sex difference in performance and pacing in the longest triathlon held in history, the Triple Deca Iron ultra-triathlon covering 114 km of swimming, 5,400 km of cycling and 1,266 km of running. A total of 14 triathletes (10 men and four women) competed in the 2024 Triple Deca Ultra Triathlon in Desenzano del Garda, with four men and three women officially finishing the race within the time limit. The data were analyzed to investigate performance differences across disciplines (i.e. swimming, cycling, and running), pacing strategies and sex differences. Variability was assessed using each discipline’s coefficient of variation (CV). The relation-ships between CV and overall rankings were examined using linear regression analysis. Men were faster in swimming (12.4%), cycling (24.8%) and running (8.5%). Cycling showed the greatest pacing variability, while running exhibited steadier pacing, with more consistent athletes performing better overall, reflecting the unique endurance challenges of this segment. Overall, men were faster than women in all split disciplines, with the highest sex difference in cycling and the smallest in running. The analysis revealed significant differences in both cycling and running times among athletes. The variability in cycling times indicates diverse pacing strategies and endurance levels, while the running times further highlight the individual performance dynamics of the athletes. The results illustrate how variability in pacing affects cumulative performance and final rankings.

Resilience against exercise-related coronary atherosclerosis: A case study in a master athlete participating in 500 marathons

Lifelong endurance exercise is generally associated with cardiovascular health benefits. However, recent studies suggest that prolonged high-volume training may contribute to coronary atherosclerosis, even in athletes with low traditional cardiovascular risk. This case report aims to explore the cardiovascular status of a master endurance athlete with an exceptionally high lifetime training volume, in light of recent concerns raised in the literature. We present the case of a 60-year-old recreational male marathon runner with no history of cardiovascular disease, who completed over 500 marathons between the ages of 30 and 60 years, covering ⁓127 000-km running. In 2024 alone, he completed 60 marathons. Cardiovascular evaluation included clinical risk assessment and coronary computed tomography angiography (CTCA). The runner was asymptomatic, had a low ESC-SCORE2 (3.3%), a favorable lipid profile, and normal levels of high-sensitivity C-reactive protein and lipoprotein (a). CTCA revealed no evidence of calcified, mixed, or non-calcified coronary plaques. This case highlights that some master athletes may demonstrate resilience to coronary atherosclerosis despite decades of high training volume. In low-risk individuals, prolonged endurance training alone may not necessarily lead to coronary artery disease, emphasizing the need for individualized cardiovascular screening strategies.

Screening for suicidal thoughts, attempts, and associated factors in endurance and ultra-endurance runners

Suicide is one of the leading causes of premature death. Prevalence of suicidal thoughts in the general adult population is approximately 4%, with lifetime prevalence of 5.6%, and suicidal attempts of 2.7%. No data are available on endurance runners (ER) and ultra-endurance runners (UER). Prospective cohort study of ER (distance of ≥21.1 km-42.2 km) and UER (≥42.2 km), collecting self-reported data on biometrics, social, psychological, medical, and training history. Suicidal risk was assessed via the Patient Health Questionnaire (PHQ-9) and open questions. Statistical analysis included descriptive, predictive techniques, and regression analysis. A total of N.=601 runners participated in the study (female N.=222; male N.=379; mean age [standard deviation (SD)] 42.8 (10.1) years). Suicidal thoughts were present in 8.0%, with a lifetime prevalence of 14.1% (P<0.001). Previous suicidal attempts occurred in 2%. Associated factors for suicidal thoughts included previous diagnosis of depression (P<0.001), anxiety (P=0.015), age (P=0.013), and participating in fewer (<9) competitions per year (P=0.026). Associated factors of lifetime risk of suicidal thoughts included previous diagnoses of depression (P<0.001) and age (P=0.015). Runners aged less <30 years of age presented with a higher risk of suicide (P<0.001) than older runners. Associated factors for previous suicidal attempts included previous diagnosis of depression (P=0.01) and stress (P=0.028). We present novel data on prevalence of suicidal thoughts in ER/UER, which were 2-2.5-fold higher than in the general population. Creating awareness among athletes, families, coaches, medical teams, and race organizers and providing education, screening and access to appropriate support are important to reduce the burden of suicide in this sport.

Sonnenstube Schweiz Marathon Tessin

Am Sonntag 27. Juli – also am Tag nach dem UristierMarathon – fand der Sonnenstube Schweiz Marathon im Tessin statt.

Nach der Flucht aus dem nassen Kanton Uri fanden wir im Tessin sprichwörtlich die Sonnenstube mit Temperaturen bis 31°.

Mit Start in Tenero galt es zuerst eine Schlaufe in der Magadinoebene zu laufen, dann zurück nach Tenero und dann entlang dem Lago Maggiore über Minusio und Muralto nach Locarno. Im Gegensatz zum Kanton Uri hatte der Marathon im Tessin praktisch keine Höhenmeter und die Strecke war mit 100% Asphalt viel schneller.

Uristier Marathon Uri

Am Samstag, 26. Juli 2025 fand der Uristier Marathon im Kanton Uri statt. Bei strömendem Regen galt es von Flüelen nach Sisikon und wieder zurück nach Flüelen zu laufen, dann auf der anderen Seeseite hinauf nach Bauen, dann wieder zurück ins Reussdelta, hinauf nach Attinghausen und dann über Altdorf wieder nach Flüelen.

Vorbei an historischen Stätten und auf dem Weg der Schweiz konnten wir wegen der unendlich vielen Höhenmeter und Kieswege die Kulisse nicht richtig geniessen, vorallem auch wegen der Kälte und Nässe.
