Sydney McLaughlin-Levrone’s defining race; Paris Diamond League TV, live stream info

For Sydney McLaughlin-Levrone, what happens in her first outdoor race of 2023 on Friday could dictate the rest of her season. It may impact her 2024 Olympic plans, too.

McLaughlin-Levrone strays from the 400m hurdles — where she is the reigning Olympic and world champion and four times broke the world record — to race her first flat 400m in two years at a Diamond League meet in Paris.

She is racing that flat 400m at USATF Outdoors at least in part because she already has a bye into the 400m hurdles at worlds as defending champion.

What we don’t know: which race McLaughlin-Levrone will enter at worlds. Her coach, Bobby Kersee, said last month that she will choose between the 400m and 400m hurdles for worlds, should she finish top three in the 400m at USATF Outdoors to qualify in that second event. She will not try a 400m-400m hurdles double at worlds.

McLaughlin-Levrone was asked Thursday which event she would pick if given the choice.

“Is it bad to say I don’t know?” she said in a press conference. “Honestly, ask me after tomorrow. I don’t know. I’ve got to run this one first and see how it feels.”

McLaughlin-Levrone also doesn’t know what she will try to race at the 2024 Paris Olympics. Next year, the 400m-400m hurdles double is more feasible given one could
