Nonbinary runners …Don/they decline to comment…
Check out the Bowerman Sports Science Center.
…Years ago, I was part of a UO study of the aging athlete. Got some of those tests, including the DEXA.
Last night I was in a 5K. Was running a comfortably low 25 minute pace when I got a left hamstring cramp or pull in the final mile. So I decided to walk it in. After a bit, I found myself able to trot the last half mile. Surprised the 27:36 wasn’t way-worse. A few weeks ago I had something like that in my right calf. Cleared up a few days later.
