The Diamond League season starts Friday with scrutiny on an event that will no doubt see significant change this season — the women’s 800m.
A landmark sports court ruling Wednesday is expected to force some top stars — including Olympic gold and silver medalists Caster Semenya of South Africa and Francine Niyonsaba of Burundi — to take measures to reduce abnormally high testosterone for women’s events.
In that case, they would have to sit out international competition through the summer, while continuously keeping testosterone levels below the imposed limit, if they want to return to any event between the 400m and 1500m at the world championships in Doha in late September.
