So, in the other half of the lane I worked on slow stroke cadence, long pulls and gliding. Worked out pretty well, every 40-lengths, I did 10-fast, with my time coming in around 4:23. In total I clocked up 130-lengths and when I got out I felt great, was breathing easy. I could have gone on, but it was getting dark, I needed a bathroom break, and was getting hungry!
50-lengths, 1250m or 3/4-mile, 24:28 total, 4:23 fast-10
50-lengths, 1250m or 3/4-mile, 24:13 total, 4:15 fast-10
30-lengths, 750m or .46-mile, 19:40 total
Total: 130 lengths, 2.02-miles, 1:08:21
So, I need to work on my pull and kick more, but try to keep the stroke cadence down. I'd like to be down around 22-mins for 50-lengths, but not by speeding up cadence. Next pool session I'm going to allocate time for 160-lengths, which puts me over the mythical 158-lengths for 2.4-miles or the IM swim just to see how my time is.
