Before locking in any 2024 Summer Olympics picks or track & field predictions on those events or others, you need to see what SportsLine Olympic insider Dan O'Brien has to say.

O'Brien is a highly decorated decathlete who won the gold medal in the decathlon at the 1996 Summer Olympics in Atlanta, becoming the first American to accomplish the feat since Bruce Jenner 20 years earlier. O'Brien also is a five-time U.S. champion and three-time world champion in the event, and he held the decathlon world record from 1992-99 and the heptathlon world record from 1993-2010. As a result of his achievements, O'Brien is a member of the USATF, USOC and IAAF Halls of Fame.

Now, O'Brien has broken down the track & field competitions at the 2024 Paris Olympics and has locked in his best bets. 

He's backing the favorite, Sydney McLaughlin-Levrone, in the women's 400m hurdles at -320 in that 2:07 p.m. ET race on Tuesday. "This year Syd has gone to another level," O'Brien said. "Breaking the world record at the Olympic trials and looking like she is ready to run whatever it takes to win this title and hold on to what is hers."
