Alastair Chalmers says he feels he has progressed to the world's elite in the 400m hurdles.
The British champion finished fifth in the Diamond League event in Stockholm on Sunday as he raced all three Olympic medallists from Paris last summer.
The 25-year-old from Guernsey broke his personal best earlier this month and is targeting the final of the World Championships in September.
"I raced against three of the best athletes in history, and that was a massive privilege," he told BBC Radio Guernsey.
"Just getting to speak to them afterwards was awesome, and getting just on that level with them was great.
"I definitely consider myself as one of the best in the world now, which is great, and of course it comes down to a lot of factors with a great coach and physio and family behind me.
"I really feel included in that kind of top, top elite in the world.
"That hasn't come kind of in a year or so; it's taken a lot of years to get to this level, and hopefully I can be as consistent as possible and stay out there."
Chalmers' next focus is the European Championship in Madrid at the end of this month before he aims to defend his British title that he has won for the past five years.
The 2022 Commonwealth Games bronze medallist said he was thriving on the opportunities the sport is giving to him.
"It's a dream come true travelling around the world running in Diamond Leagues or the Europeans or the Worlds and getting rare opportunities," he said.
"I opened up my season this year in Tokyo, where the Worlds will be, and that was an amazing experience.
"It was a 14-hour flight, and it's pretty crazy to think you've travelled 14 hours for a 49-second race, and, of course, a lot of people don't understand how that has effects on the body doing those long-haul flights.
"It's amazing, and when I'm done with this sport, just looking back on the opportunities I got given and the work I put in, I really hope I look back and look at it very fondly."
