I'm back in the water training for the first time since college -- 20+ years ago. It took a little while but I'm up to 3k/work-out, but predictably a lot slower than when I was a kid. I'm trying to get some sense of what intervals to set/keep during sets. Right now it's pretty much a survival thing: 50's on a minute, 100's on 1:45 and 200's on 3:30. That's as fast as I can go and still do 5-10 to a set. What kind of intervals are we "more mature" swimmers doing?
