So are the IOC also acknowledging that without the suppression of testosterone (to a greater degree than previously claimed) trans gender women may have an unfair physical advantage due to nature of male biology?
this being the case then...
Several other major marathons said they have no official policies but are taking a similar approach to Boston. Organizers of the Chicago, New York City, London and Los Angeles marathons all said they honor the gender that runners submit during sign-ups.
"We want to be inclusive and sensitive to all of our participants," said Carey Pinkowski, Chicago Marathon executive race director. "At this point, we don't feel that we need to require legal or medical records or anything along those lines."
But there's still a wrinkle: Many races, including Boston, New York and Chicago, require runners to show IDs with the same names and genders as their application forms, which can be an obstacle for trans athletes who haven't legally changed their personal information. Race officials said they haven't fielded complaints but will monitor their policies to make sure they're inclusive.
In elite competition, debate has mostly focused on transgender women, who typically require surgery or medication to lower their testosterone levels. Olympic officials issued new rules in 2016 saying trans women can compete if their testosterone levels stay beneath a certain limit, and many professional races now follow similar rules."
In response to the March blog post, some commenters said transgender women have an unfair physical advantage and shouldn't bump other women from qualifying.
Stevie Romer, a transgender woman from Woodstock, Illinois, says she registered for Boston as a woman because that's what she is. Although she hasn't done anything to lower her testosterone levels, Romer legally changed her gender, grew her hair out and started living openly as a woman more than a year ago.
"To be able to experience it as me was really, really important," she said. "I've been a runner since as long as I can remember. I love running, but I just happen to be transgender."
