Sorry, this is more of a rant than anything else, but I just had a disappointing and mediocre swim workout because I forgot my ear plugs. I ended up doing everything but the crawl, which was good cuz it made me be creative and add variety, but it sucked cuz that's the center of all my swimming. Actually, yesterday really REALLY sucked. I somehow lost my trunks, goggles and ear plugs all in one session but did not realize it ... and then it took subsequent workouts to figure out each missing equipment. So finally on the third trip to the gym when I realized I had no ear plugs, I said screw it. The first 5 minutes were some of the most miserable moments in the pool as I remember why I can't swim without goggles or ear plugs. And then I remembered reading this post and remembered there was something about "ear infections" in there and realized I should stick with only non-side-turning strokes.
Actually I just got inspired for a solution for you, Dark. Swimming ear muffs
, haha! ;)
