When Diplo ran the Los Angeles Marathon last weekend, breaking the four-hour mark with Olympian Alexi Pappas by his side, that was impressive enough. The 44-year-old DJ said he hadn’t done a proper marathon build in preparation; he was under-trained and pulled off a fantastic finishing time of 3:55:16 anyway. Now he claims the entire 42.2K footrace was one big acid trip.

On Wednesday, he revealed in an Instagram post that, because the longest he’d ever run previously was 17K (technically untrue according to his previous half marathon results), “I did what any normal person would do and took LSD” (the psychedelic drug, not “long slow distance”). Before the marathon, he’d also shared his oddly specific goal — which he met — of beating Oprah’s 1994 PR, when she ran the Marine Corps Marathon in 4:29. Some folks call it “the Oprah effect.” Diplo brought some bravado to Instagram on that front as well, saying, “I ate that. Sorry Oprah.”

He went on to thank Pappas for pacing him, and said, “Shout out to my knees which will never be the same, and my kids for waiting for me at the finish line. If anyone needs me I’ll be sitting down.”

Another runner, Michael Versteeg, has spoken about incorporating psilocybin mushrooms into his experience running the Cocodona 250, a 400K+ ultramarathon from Black Canyon City to Flagstaff, Arizona. Versteeg microdoses for his long runs and says while it’s not the same as full-on tripping, “you’re experiencing colours, you’re experiencing the landscape in a much more vivid way.”

The trusted advice many runners abide by is “nothing new on race day,” but Diplo doesn’t exactly play by the rules.
