The Alpine Seven · Bernhard Hengl

Seven Alpine lakes. No wetsuit. One stroke at a time.

The Alpine Seven began with my cancer. Today I swim for everyone life has pulled the ground out from under, and who is ready to swim again.

Every lake is proof that you get further than you think.

Walensee & Lake Zurich

70 km, non-stop, without a wetsuit. August/September 2027. The longest swim of The Alpine Seven so far.

Why I swim

It started with 5 %.

In March 2016 I was diagnosed with cancer. Within weeks, the body that had won nine national water polo titles could barely walk 500 metres. During chemotherapy I set myself a goal: my tenth national title. The odds were about 5 %. In June 2017 we won it as a team.

That is where my principle comes from. You don’t need to be back at full strength. 5 % is enough for the first stroke.

The Alpine Seven started as a way to raise awareness for people living with an illness. Today I swim for everyone whose ground has gone and who doesn’t know yet where to swim. There are no medals for these crossings, and it’s not about records. Each lake shows that with a goal and one stroke at a time, you get further than you think.

Make 5 % your 100 %.
