BTS really had a packed schedule during their tour stop in Stanford … ’cause it turns out SUGA competed in a race before taking the stage on Sunday — and he put his “blood, sweat and tears” into it.

The footage of Yoongi’s outing surfaced on Wednesday … showing the rapper trotting alongside a bunch of normies who probably had no idea they were in the presence of a K-pop idol.

The event was a 12k called Bay to Breakers … and while it’s known for contestants wearing costumes, the artist kept it casual with black athletic clothes and a blue hat.

According to the race’s website, SUGA did his thing — finishing the 7.45 miles in one hour, four minutes and 43 seconds … averaging an 8:41 mile.

He finished 1,022th overall and 835th in the male category for his race … so his “Run” lyrics, “I run and run, but I’m not getting anywhere” don’t really apply here — the dude was movin’!!

After the BTS members revealed Yoongi’s fitness endeavors, it didn’t take long for the ARMY fanbase to search through all the footage of the race … and sure enough, their beloved member popped up in several clips!!

There wasn’t much time to recover … as later in the night, he and his groupmates went on to crush another show of their “ARIRANG World Tour,” even if our eyewitness (the guy writing this post) noticed a slight limp in SUGA’s gait later on in Sunday’s set.
