Training - Swimming

Okay, I've talked about why. The toys are fun. Doing good is a plus. But, don't you eventually have to sweat a bit to get ready for a triathlon?
The answer is yes. When I started this process earlier in the year, I literally did not know if my body would handle the stress of more intense training. The good news is that I am cautiously optimistic - so far, so good.
Swimming; "Back in the day" (circa 1975) I could go two practices a day and cover roughly 10,000 meters - every day. The sprint distance is only about 750 meters. So, how hard can this be?
Well, let me tell ya'. My first "workout" I started to get really tight after about, oh, 100 meters! I did a few flip turns but pretty soon I'm too out of breath and my "turns" were getting a bit sticky (meaning I was cheating and hanging on to catch my breath). I made it 15 laps - or, about 375 meters. The good news is, my speed is coming back and my endurance is improving at a decent pace. My work out on Sunday morning (before Church) was 2,000 meters (that's 40 laps) and I felt strong - and no hanging on the wall! Watch out!
