Diplo was among the thousands of runners participating in the L.A. Marathon on Sunday ... and his time was mad decent -- finishing the thing in under 4 hours!!
The famous DJ completed the 26.2-mile race in 3 hours, 55 minutes and 16 seconds ... which was 1,661st-best for men and good enough for 2,013th overall!!
The 44-year-old had made his target time known prior to the race ... saying, "tbh all that matters is that I can beat Oprah Winfrey time (she was pretty fast)."
BTW -- Oprah was a bit of a speedster herself in 1994, completing the Marine Corps Marathon with a time of 4:29:20.
Olympian Alexi Pappas -- who ran alongside Diplo during the race -- gave the producer his props in a congratulatory Instagram post ... saying, "We were total gazelles out there."
Diplo is a bit of a freak athlete -- he also ran the Miami Half Marathon with zero training in 2022 ... and proceeded to hit the club right after.
It appears Diplo elected for a cig and some compression therapy boots this time around ... but we're sure he'll be back on his feet in no time.
