La BAT Race a unique under the ground SUP Race

Have you heard of the BAT Race ? Would like to register ? The BAT Race, one of the most famous Alpine Lakes Tour Races, is usually held in the middle of March….

The BAT Race is, according to the late SUP Race magazine SUP Racer, the most unique SUP Race in the world. This event is all the more exceptional as it is only organized every 4 or 5 years. The last edition dates from 2022 and the next is planned for 2025.

This underground lake in Switzerland is no ordinary body of water. Lake St. Leonard holds a constant, year-round air temperature of 15 degrees Celsius (59 F) and water temp of 11 (52 F).

The Bat Race will also be unique because it’s usually forbidden to stand up paddle on Lake Saint Leonard. Organisers have been granted special permission to host this one off race, and only a handful of paddlers have been allowed access to the lake.

Due to the very obvious space restrictions, entries for the Bat Race is limited to 60 paddlers and a few spectators.

BAT RACE 2022 : the results !

The BAT RACE 2022 is over ! Thanks to all participants who took the usual challenge to compete in a SUP Race… under the surface of the earth !

The Alpine Lakes Tour has struck a blow again at the start of the season with the return of the BAT Race: the only underground paddle race!

Saturday March 12, 2022, stand-up paddle enthusiasts from Switzerland, France, Italy and even the Czech Republic and Poland had an appointment for this reissue of a world first at Lac de St-Léonard, the largest underground lake in Europe, located in Valais (Switzerland).

The fact of being underground, almost in the dark, gives a very unique atmosphere to this race.

A very feminine race 

It’s rare enough to point it out: there were more women than men yesterday at the BAT Race with a very high level!

A paddle tournament

Competitors competed in a tournament with a women’s board and a men’s board. All participants were able to run at least 3 times.  

The equipment (paddle, vest, paddles) was provided by the Alpine Lakes Tour’s sporting partner: Red Paddle Co, inventor of the inflatable stand up paddle.

A race in disguise!

The theme was naturally that of superheroes! But not everyone had to be Batman or Batwoman… A special prize was awarded for the best costumes!

 The underground lake of Saint Léonard

The underground lake of St-Léonard is located in Switzerland, between Sion and Sierre, in the heart of the Valais Alps. This lake nestles between 30 and 70 meters deep. With a length of almost 300 meters, it is the largest natural and navigable underground lake in Europe. Weakly influenced by seasonal changes, the temperature of the cave is constantly around 15 degrees, that of the water at 11 degrees.

Open to the public from March to October, the lake can be explored by taking part in guided tours on boats with a capacity of 40 people. Original events are regularly offered there, such as aperitifs or concerts on board the boats. 

The official opening of the lake to the public for the 2022 season will take place next weekend.

Navigating the lake on a stand-up paddle is totally unique and reserved for this stage of the Alpine Lakes Tour.

The Bat Race : The World’s First Underground SUP Event

st-leonard-corne-suisse-600The Bat Race  : The world’s first underground stand up paddling competition on Europe’s largest underground lake in St-Léonard, Valais, Switzerland on 14th March 2015.

Riders will compete in sprint races in a double elimination tournament. Time for strolling on the lake and fun activities are also on the day’s schedule.

The event is baptised Bat Race in reference to the mammals that populate the cave where the event will take place.

Registration, limited to 40 riders, opens on 24th February 2015 at 20:00 CE on this website. Get ready !

Recently named a candidate for “the world’s most beautiful SUP race series” shortlist on, the Alpine Lakes Tour features races on the Alps’ most breathtaking lakes. No waves or coconut trees – here it’s crystal turquoise water, wild nature and snowy peaks that build the stage on which the tour’s competitors race year-round since 2013. Initially held in France and Switzerland, in 2015 the tournament will extend its reach to Italy with a race in the city of Turin. The tour launches its third edition with this world premiere organised with Swiss partner Alps SUP.

Lake St-Léonard is Europe’s largest underground lake. The about 300 m long pool is housed in a cave hidden in mountainside in the beautiful region of Valais, known for its vineyards, apricot orchards and world-class ski resorts. Mostly unaffected by the seasons change, the lake’s water is at a constant 11°C year-round and the air temperature in the cave averages 15°C. The lake is open to the public from March to October and can be visited through guided tours, which bring visitors on a rowing boat tour through the lake’s several bays.

Stand up paddling on the lake is forbidden and has been granted exclusively to the Alpine Lakes Tour for this unique event!

Event description

In order to avoid overcrowding and guarantee the lake’s magic stillness to all participants, registration is limited to 40 entrants. 25 further non-competitors can register as spectators. They will have the chance to paddle on the lake and take part to the SUP game scheduled at mid-event. One-design 12’6 inflatable race boards will be provided by the organiser. Competitors will be free to use their own paddles.

The tournament includes 3 rounds of which all competitors will race at least the first two. A different course and distance is planned for each round:


Round approx. distance buoy turns competitors per heat
Round 1 1 km 3 4
Round 2 550 m 4 4
Round 3 500 m 1 5
Final 1 km 3 6


It’s a tradition of the Alpine Lakes Tour to organise a SUP game (a SUP-related innovative and fun activity) at each event. Such a game will take place at one end of the lake at mid-event and will be open to all competitors, spectators and volunteers. Extra boards will be provided for free strolling on the remainder of the lake.
