Allgäu SwimRun – An authentic race in the beautiful alpine foothills

The Swedish endurance sport swimrun comes to the Allgäu region for the second time. Here, between the foot of the Alps and idyllic lakes, in the most southern part of Germany, the Allgäu SwimRun 2017 will take place. Gentle trails and the clear waters of the Allgäu lakes makes this the perfect location to cross new boundaries.


The route consists of 7 running sections in total of 23,5km (560 m positive altitude change), as well as 6 swimming sections in total of 3.5km. The estimated water temperature will be between 12 – 14° Celsius. The race is suitable for swimrun beginners, but has enough potential to be challenging for experienced swimrunners, as well.

Results are on the way – International swimrun equipment test

This weekend, World of Swimrun (WoS), Swimrun France (SR-F) and Swimrun Germany (SR-G) teamed up in Marseille, France for the 1st ever international swimrun equipment test. During 4 days, the teams tested and debated some 70 swimrun equipment items from more than 40 manufacturers.

What a weekend!

The 1st ever swimrun equipment test was a huge success. Contrary to normal sunny conditions in the rugged and steep terrain of Calanque de Sormiou, Marseille, our test was conducted in rain, storm-winds, huge waves, strong currents and sun. We definitely got the chance to test the swimrun equipment in all types of conditions.

Gravity Race 2016

Emmanuel Charpentier shares his experience of the Annecy Gravity race where he competed alongside Yves Louis. The race takes place in France around the lake d’Annecy. It’s a hilly race: 5km Swim – 34.5km Run with 2100m of ascent.

After 20 years of athletics (Track and Cross-country) and 10 years of triathlon (All distances), I found myself yearning for more authentic and natural courses more specific to my profile as a swim-runner. So, I decided in 2015 to try my hand at the Troll Enez Morbihan… It was love at first sight! I had found a new form of adventure in Swimrun.

On the Friday before the race, I meet up with Yves Louis, originally from Besancon, who is an experienced trail runner and triathlete of 2 years (He did 13hrs15 in Embrun in 2015). It’s raining and it’s hard to imagine that sunshine has been forecast for the day after next. We’re going to test out swimming roped together to decide whether to do it on race day. After a short time trying them out, we decide to go with the rope. We also discover that the water is not exactly what you would call warm. (14-15° with lows of 5° in the last 15 days).

Buying the right wetsuit – A matter of life and death?

Working that tight neoprene – Team Sportextreme Daniel and Philip

Swimrun differ from most aquatic oriented multi-stage sports in that you actually run on land in a wetsuit, in-between the many swim stages and most of the time with your wetsuit fully on.

But how does wearing and running in a tight and mostly black neoprene wetsuit affect your body?

We have previously discussed the science around doing exercise in a wetsuit where studies have found that it will protect you from hypothermia, but might cause overheating. And finding that perfect balance can actually make you go longer and harder than you normally do. But doing exercise in a wetsuit this is not without risk. A recent study by Prado et al (2017, below) has investigated this phenomenon in triathlon, a multi-sport that puts pressure on one’s overall physical capacity. As it turns out there have been 43 event-related deaths from 2003-2011 and the majority occurred during the swim stage. To date there is no clear explanation for the deaths but autopsies report evidence of cardiac abnormalities, hypothesising that immersion pulmonary oedema (IPO, a.k.a swimming induced pulmonary edema, SIPE), can be a potential cause of death. In comparison, the risk of death during a triathlon has been reported to be 1.5 per 100,000 participants compared to only half the risk during a marathon, at 0.8 for every 100,000 participants.
