My local Y has 30 minute slots...obviously, one to a lane, and it is very hard to get a spot (you have to reserve 0-48 hours from your time slot, and they all get snapped up within 0-3 seconds). I am not exaggerating. I was managing to get in a few doubles, but then they banned those. I'm averaging about two swims a week, because you have to be lucky.
The upside is I have to be lean and mean. I don't swim non-stop and the most I can manage is about 1500. The 30 minutes is actually more like 28, since there is no gap between reservations.
So, what is a good workout for 30 minutes? I mostly swim for fitness, but I typically also do 3-4 meets a year and swim only 50s.
