The Diamond League for 2025 is upon us, and the Brazilian 400m star already knows the ropes of the competition. He won the Diamond League title in the 400m hurdles twice, in 2022 and 2024. The 25-year-old is also familiar with the limelight that comes from winning bronze medals at the 2020 and 2024 Summer Olympics and a World Championship title in 2022. But enough about the accolades of the sprinter, who became $200,000 richer after winning two Grand Slam Track events in Kingston and Miami in 2025. So many achievements at such a young age, but does that make him a favorite?

As he clears hindrances to pave the way for future stars, while chasing to buy a Lamborghini with his prize, let’s see what he said about this. The men’s 300 m hurdles will be the center stage at the Bislett Games, also named Oslo Diamond League, on June 12. The three quickest athletes in the 400m hurdles record, Rai Benjamin, Karsten Warholm, and Alison dos Santos, will face off in this intense matchup over shorter barriers. Before they could sprint at their fastest pace, the athletes sat down for a chat with living legend Kevin Young.

The 1992 Olympic gold medalist asked him if dos Santos would be the favorite, since he had won several events now. The two-time Olympic medalist gave a humble reply stating, “I don’t think so. I would say in the stage that we are in right now, you can’t just have your favorite, you know? You’re gonna have all of us running tomorrow to prove who is the fastest in the 300m, and I am excited that it’s a different event. Gonna be like official, so you know, we just come on here and run with those guys, and like I am really, really proud to be a part of this just. I am excited.”

This is not the first time that dos Santos is going to run in the Diamond League being held in Oslo. He has been to Oslo for the 2021 Diamond League, where he set a new South American record, with a clocked time of 47.38. Further, he conquered Karsten Warholm in his own country and became the leader in the 400 m hurdles ranking for the year, with a time of 46.63.

So, before he blazes through the 400m in Oslo, let’s look at his season until now.

Alison dos Santos sprinting through 2025

Alison dos Santos has participated in several Diamond League events over the years. In 2021, he competed in 6 events, and then in 2022, he participated in 7 Diamond League encounters. In 2024, dos Santos competed in 6 Diamond League hurdle sprints and won 5 of them.

Despite undergoing knee surgery on February 14, 2023, due to a meniscus tear in his right knee, he came back stronger. The surgery was required to heal the injury, and his recovery period was expected to be 8-12 weeks. He successfully returned to competition on July 16, 2023, and his first race after the injury was the Silesia stage of the Diamond League. 

The towering Brazilian and one of track’s biggest personalities is in full swing this year as he has already set a new world lead in men’s 400m long hurdles during the Grand Slam track in Jamaica. Other than that, he also aced his Kingston performance with a world-leading time of 47.61 seconds. Before he won the GST in Jamaica and Miami, he had sat down to chat with Sportsmax back in April 2025 and said, “We expect to run good (today) and on Sunday,” he said. “But I can’t promise I’ll run 46.2 or 47.0. It’s too early. We’re laying the groundwork for the rest of the season.”

And he delivered more than he led on. Whether or not the clocked times are electrifying this weekend, Alison dos Santos is playing the long haul. And the game starts now. What do you think?
