Lately swimming is a lot more painful - cant figure out why?

I have been swimming for 40 years (I'm now 52). I regularly attend masters swim practice (3 X week). Recently, I have been struggling a lot in practice when I try to push myself at 90% or on harder efforts. I feel incredibly fatigued even in a short sprint like a 100 I.M. I feel very comfortable swimming at 80% effort for a really long time but as soon as I push myself a little more the wheels fall off in a big way, and I don't recover very well. I have been to the doctor to get checked out and had my blood work...everything is great. I'm wondering if this is just age or maybe my diet is affecting me?? I have not made any changes. Has anyone else around my age experienced this? Thanks.

  • I go 3 times a week. I really don't do well with more than 3 days/week. I'm thinking about having 1 day be my "easy" day and really lay off the hard efforts and just work on technique those days. Thanks for the feedback.
