SOLD OUT
In 2025 this event is a Founders’ Pioneer event?
As previous participants and invited swimmers only, you are helping us create new events as part of the UltraSwim 33.3 series. These events are pioneering new venues, validating our hotel choices, helping us define the courses and the logistical solutions - in an intimate 20 swimmer max environment much like our very first #1Montenegro in 2022.
This smaller group environment gives us all time to spend quality time together, over dinner or during the transfer time - something not so easy once we are full-scale.
A smaller event is relatively more expensive for us to put on, and we can’t offer all the options we might normally, but this will be more than made up for by the intimate nature of the event. The on-water safety will not of course be compromised, and whilst the ULTRA+ package on offer has some small differences to other events, the post swim massages will be provided!
THE VENUE
Lake Geneva (more correctly known as Lac Léman) sits between the Swiss and French Alps, and the Swiss/French Jura - with Geneva at one end and Chillon/Montreux 70km away at the other. This fresh water lake provides an incredible swimming venue, with amazing 360 degree views, and UNESCO heritage vineyards rolling down to quaint Swiss and French villages on the lakeside. Home to Inspire Through Sport, the company behind UltraSwim 33.3, this venue establishes the first non-salt water event in the series. Also co-founded by Mark Turner, this will also be the first event where a charitable cause is put at the heart of an UltraSwim 33.3 - and hopefully will touch the hearts of the participants, as they Swim for Hope! Léman hope is a Swiss charity that provides 5 day sailing trips to young cancer survivors to help them rebuild confidence after the destructive treatments they (and their families) have been through.
THE COURSE
This course takes us around the eastern end of the famous Lac Léman (as known locally), Lake Geneva as known internationally, starting at the Chateau de Chillon, passing famous Montreux Jazz Festival landmarks (hello Freddie Mercury), underneath UNESCO protected steep sided vineyards and quaint Swiss villages, with the Alps in the background and an iconic 13km crossing between Switzerland and France on Marathon Day 3. Lake temperature can vary greatly according to the preceding weather - we’d expect 20-23C range however as the lake, which gets very cold in winter, warms up constantly throughout the summer months.
SWIMMING CONDITIONS
As summer draws to a close, early September can be a stunning time to swim on this lake - the tourist season is winding down, the schools are back, and the lake can show its too faces…mirror like conditions, or, and in particularly at the end of the afternoon, the end of summer thunderstorms. Swims will start as usual early in the morning (sunrise around 7am, so not earlier than that!), and you can be assured of some amazing sunrises from behind the Swiss Alps.
Whilst calm conditions are the norm - either the thunderstorm conditions, or the famous ‘bise’ wind from the north, can whip the lake up pretty quickly with short sharp waves to manage. But we’re not on the ocean here…most conditions are swimmable!
TRAVEL AND LOGISTICS
This is a Friday to Monday lunchtime event. Arrive at the very well connected Geneva airport by 1400 (50 minute train direct from airport to Lausanne) on Thursday 4th September. Departure possible on flights from Geneva Airport scheduled departure from 1630 - again direct trains back to the airport are at least 2 an hour.
This event will also focus on minimising its carbon footprint by using public transport (trains and ferries) wherever possible.
The Purpose!
Since 2019, Léman hope has been using sailing as a therapeutic tool to help children in remission from cancer regain self-confidence, during a 5-day, 4-night cruise on Lake Geneva.
This experience, a true bridge between treatment and an active future, embodies values of courage, sharing and hope. Léman hope aims to support these young people in their reconstruction after cancer, by offering them a caring environment where they can rediscover themselves and leave with optimism. The magic works, and each young person comes out of this human adventure with newfound growth and resilience.
An automatic donation of 50CHF per participant is donated from the entry fee, and further fundraising events allowing swimmers to understand better the incredible work this charity does will be held during the event.
