Chlorine is put in pools to sanitize it — it bonds to the gunk you leave behind (you do know you leave behind gunk, right?) and turns the gunk into organic “Chloramines“, which sounds so much nicer than gunk. Those organic compounds then ostensibly get filtered out so we can all go enjoy the pool.
Chlorinated pool water tastes awful, by the way.
I checked out the Mercer Island pool this morning (at 6:30 AM, yo!) and did some laps; as I suspected I am woefully out of swim shape. While I actually can be faster (with my lap time I could get a half mile done in 16 minutes!) I don’t have the endurance (that would be 16 minutes plus another 16 worth of breaks!) and I have but four weeks (oh, slightly less now) to get that in gear.
I will note that the Mercer Island pool has just enough chlorine to sanitize and not so much that it makes your eyes horribly red; and unlike the LA Fitness in Bellevue it does appear as though they clean it occasionally. The locker rooms leave much to be desired — body consciousness is not a privilege you have there — but they are serviceable. There are actually seven (7) signs in the locker room reinforcing basic hygiene (wash your hands, wash your kids butt after diaper changes and before putting them in the pool, and – I kid not – do not let a kid with diarrhea swim).
Biking is still my favorite.
