The 2023 NOBULL CrossFit Games Open has come to an end, and two athletes stood atop the worldwide leaderboard at the close of competition.

At the age of 18, O’Brien became the youngest athlete to win the Open and the youngest to podium at the CrossFit Games in 2022, taking home the silver medal. 

She is heading down the same trajectory this year, once again winning the worldwide Open. She took top five in three out of the four tests, winning Open Test 23.2A with a score of 188 reps. 

Will we see O’Brien step into first this year and become the youngest to claim the title of Fittest on Earth?

For the second time, Adler has swept the Open leaderboard, much like he did in 2021. Although he did not take home any single event wins, his consistent top-60 finishes secured his lead. His best finish was in 23.3 when he took fifth place with a score of 8:01. 

Every year since 2019, Adler has attended the CrossFit Games, with his best finish being fifth in both 2020 and 2022.
