I decided on my way home from work yesterday that rather than watch the TTT masters swim workout (I would be there since Courtney, daughter#2, swims with the junior team)I would try a swim to test out the ribs again. The problem was that the last time I tested them out I thought I was OK until about 30 minutes after the swim and then agony set in. And it lasted for days.
The pool was set up for 50m lanes. I figured 4x50 with fins would do the trick and that I would avoid the pull buoy from the beginning so I don't need to wean myself off it later.
I did OK taking a long time between 50s. I found it funny how the habit of looking at the pace clock at the end of every interval is ingrained into my swimming technique. I woke this morning and I was still OK. Pain no better, no worse.
Success! I'll try again on Wednesday.
