Team TWS: Henry and Susanne Wahlig right before the start

It´s not easy to walk out of the water but Jürgen Keck and DLRG are a good support for Henry

Even the local newspaper dedicated an article to Henry

Henry Wahlig swims for research into HSP

1,500 metres across a part of Lake Constance, despite being in a wheelchair!

Nine years after taking part in the Gnadensee Swim for the first time, Henry Wahlig has once again completed the approximately 1,500-metre swim between Allensbach and the island of Reichenau.

Yet the challenge is even greater today than it was back then: Henry, who lives with the rare neurological condition HSP, spends most of his daily life in a wheelchair. This makes it all the more impressive that he took on the long-distance swim again on 18 July 2026 – and even beat his personal best in the process!

On the day, Henry was supported by the DLRG, TWS ‘Stepmaker’ Jürgen Keck and his family. Through his challenge, he has shown what is possible when courage, solidarity and commitment come together.

TWS would like to thank everyone for the numerous donations that Henry ‘swam’ for HSP research. Further donations are, of course, still welcome – click here for our foundation’s donation button!
