My partner Liz is a runner, and me not so much, so imagine my surprise when she harrassed me for not even giving her latest "Women's Running" Magazine a second look. On the cover was a full length shot of Ameila Gapin runner first and transgender woman second.
The magazine itself did a wonderful job of taking on the task of the challenges trans women face when they compete as far as gender markers, testosterone levels etc.
I am not a runner, but I will gladly tell anyone who will listen, how estrogen and HRT will sap your body strength before you know it.
Ameila goes into it as only a dedicated runner can in this article. Plus, you can follow her SRS challenges on her blog link above.
