Not a sport exactly, but it runs on the same rhythm as the rest: announced in the chat, entirely optional, available all year round on request, and much easier with other people standing next to you. The Atlantic here sits around 19 to 24 °C depending on the season, so this is genuine cold exposure rather than a novelty, and it pairs naturally with whatever you did on the rooftop that morning.
Distances are straight-line from U32.
Every sport here, and what the island adds - the map, all eleven sports we run or equip, and the ones that are simply close.
