This summer I have noticed that if I don't shower immediately after a run I start to smell like buttermilk. Very sour. Even if I shower then my sweaty running clothes sitting in the hamper smell like buttermilk.
I used to smell like ammonia after a run, which was a little more bearable.
What happened to me? By the way, I never drink buttermilk. I can't stand the taste.
