SuretoSure Swimrun

SuretoSure Swimrun Swimrun is an endurance sport where teamspirit is central to survival in teams of 2 We hope to welcome you in Luxemburg for an unforgettable challenge!

This truly unique endurance race combines swimming shore to shore across majestic reservoir lakes of the river Sure with trailrunning through dense forests on the hillsides surrounding it. A challenge made for those who love the adventure of running along raw nature trails as well as swimming out in the open. Thomas Van Praag, Nick Van Praag, Yann-Alexandre Tytgadt

Dear Sure to Sure Swimrun Participants,

After a long deliberation with the organising committee and reviewing the latest weather forecasts, we have made the difficult decision to cancel the Sure to Sure Swimrun 2026.

The forecast for Saturday indicates exceptionally high temperatures in the Lultzhausen area. After a thorough risk assessment, we believe these conditions present an unacceptable health and safety risk for participants, volunteers, and staff.

In reaching this decision, we considered several factors. Large sections of the course are relatively remote, with limited access for rapid evacuation or medical intervention. Several climbs are steep and exposed, offering little protection from the sun during the hottest part of the day. In addition, with the Centre Sportif unavailable, we are unable to provide adequate shaded facilities in the start and finish area.

While experienced endurance athletes may be capable of performing safely in these temperatures, we have a duty of care to all participants. Despite closely monitoring the situation and exploring a range of mitigation measures, we do not believe we can provide a sufficiently safe racing environment under the forecast conditions.

We know many of you have trained hard and were looking forward to this event, and we are deeply disappointed to make this announcement. However, participant safety must always come first. 

All registered participants have received an email with more information about the registration transfers or refunds.

(Way too) Warm regards

Thomas, Nick & Yann

Dear Sure to Sure Swimrun Participants,

Unfortunately, we have some sad news to share.

After meeting this evening with the organising committee and reviewing the latest weather forecasts, we have made the difficult decision to cancel the Sure to Sure Swimrun 2026.

The forecast for Saturday indicates exceptionally high temperatures in the Lultzhausen area. After a thorough risk assessment, we believe these conditions present an unacceptable health and safety risk for participants, volunteers, and staff.

In reaching this decision, we considered several factors. Large sections of the course are relatively remote, with limited access for rapid evacuation or medical intervention. Several climbs are steep and exposed, offering little protection from the sun during the hottest part of the day. In addition, with the Centre Sportif unavailable, we are unable to provide adequate shaded facilities in the start and finish area.

While experienced endurance athletes may be capable of performing safely in these temperatures, we have a duty of care to all participants. Despite closely monitoring the situation and exploring a range of mitigation measures, we do not believe we can provide a sufficiently safe racing environment under the forecast conditions.

We know many of you have trained hard and were looking forward to this event, and we are deeply disappointed to make this announcement. However, participant safety must always come first.

All registered participants have received an e-mail with information about their registration.

For those who have all the arrangements to be in Luxembourg this weekend and who are keen to get out there, we would suggest a relaxed swimrun training opportunity on early Saturday morning before the heat. There will be no timing, no ranking, no course marking, no checkpoints, no safety cover, no aid stations, and no event services, but it will be an opportunity to recce (some of) the course in a relaxed setting. Please take sufficient supplies along and take full responsibility for your own safety.

We understand that this news will be disappointing and sincerely appreciate your understanding. Thank you for your continued support of the Sure to Sure Swimrun. We look forward to welcoming you back to Lultzhausen on 26 June 2027.

If you have any questions, please do not hesitate to get in touch

Kind regards,

The Sure to Sure Swimrun Team

Flying solo but determined to race? Don't worry, we've become surprisingly good at playing swimrun Cupid!

Success rate: Fairly high. 📈

Guarantees: Absolutely none. 🤷‍♂️

(Basically, just like love itself.)

If you need a teammate, drop us a message and we’ll try our best to find your perfect race partner!
