Any male-to-female transgender athlete who went through male puberty won’t be able to compete in top track competitions. The DSD restrictions have major implications for athletes such as Francine Niyonsaba.

We take a look at Covid-19's impact on the running world and wonder if it might actually result in Eliud Kipchoge debuting in New York this fall. Plus what do actor Luke Wilson's HS track exploits tell us about Caster Semenya's Olympic 200 dreams?

In a decade marked by controversy, it's fitting that Alberto Salazar is our Person of the Decade as controversy clung to Salazar like a paperclip to a magnet. Plus who wins our world and US athlete of the decade honors?

The 3k is ridiculously stacked (Dibaba vs Ayana vs Hassan vs Obiri). Heck, EVERY event is ridiculously stacked. The women's steeple features 6 of the 8 fastest women ever, the 1500 has Houlihan vs Muir vs Kipyegon, and the 800 has Semenya. Oh boy.

Veteran journalist Amby Burfoot has read the full 163-page decision, which was released on Tuesday, in its entirety, and offers his take on the most interesting details that were revealed.

On Thursday, for the first time since 2015, a Diamond League women's 800-meter race will be won by an athlete that is not 46 XY DSD. As an event, the women's 800 is about to change, massively. The question is, how?

Since the mainstream media's reporting on Semenya has been so biased, Robert Johnson thought it was important to clear up three common misconceptions about the Semenya case.

The 1968 Boston Marathon champ who wrote a 5,000+ word piece in support of the IAAF's regulations regarding Caster Semenya says he felt "no joy" when he read the CAS decision yesterday, and is now actually hoping the IAAF lets Semenya run the 1500.

For the third year in a row, Caster Semenya was undefeated but was this the last of her dominance?  Domestically, Ajee Wilson was the best of a strong group of US runners. Should US#3 Ce'Aira Brown be ranked in the world's top 10?
