I went for a swim in the Allas Sea Pool today, again. Except that now it is February, and it is -5 C outside.
But, the pool was warm. I bought a swim cap to protect my head, and managed to swim 500 m in the rather crowded pool. The crowd was not on the furthest away lane, however :-)
And it was amazing. You're in a warm pool, light torches blasting from under the water and lighting also the steam rising from the pool... and you see the purple Ferris wheel above you... and occasional glimpses of Helsinki's historic buildings through the fog... and now and then a ferry speeds past the pool. What a place!
I did not, however, dare to enter the cold sea-water pool. Brr.
