What swimmers say!
Melina, France 2025 — relay crossing with friends
"I grew up watching Fort Boyard on TV — it always felt like a place I'd only ever dream about. Swimming to it was my way of getting there without being on the show. At one point during the crossing I looked up and the fort was right there in front of me, in the middle of the open sea. I didn't have the words for it. As for the organisation — we had nothing to think about except swimming. Everything was taken care of. We just had to show up and be in it. "
