A rare, perhaps unprecedented, matchup of Olympic women’s 400m and 800m champions headlines a Diamond League meet in Rabat, Morocco, on Sunday.
Bahamian Shaunae Miller-Uibo and South African Caster Semenya are both entered in the 400m. Coverage begins on Olympic Channel: Home of Team USA and NBC Sports Gold at 2 p.m. ET.
It’s the first time in recent history, perhaps ever, the reigning 400m and 800m gold medalists go head-to-head in an individual race. The comprehensive track and field statistics website Tilastopaja.org shows no other instances since the women’s 400m was added to the Games in 1964.
