Coldplay's Chris Martin has been taking the tour part of his band's international tour very seriously, going for long, solo, walkabouts in the cities that he performs in.
This meant that eagle-eyed residents of Jakarta might have noticed the Coldplay frontman striding through their city barefoot just before the band's Nov. 15 concert.
An Instagram post showed Martin and band manager Phil Harvey taking a selfie on an overhead bridge in Jakarta.
The pair, drenched in sweat but beaming from ear to ear with the caption "epic walk in Jakarta".
But what would have really taken people by surprise is probably the next picture in the series showing Chris Martin walking barefoot by a body of water.
The Jakarta Post identified the location as Jl. Galunggung, next to the Setobudi reservoir.
Commentors on the post expressed concern about Martin's choice to go barefoot, with one urging him to be careful, and another asking if his feet were blistered.
Other social media users posted about seeing Martin on his "epic walk", with Coldplay fan account @idwantscoldplay posting @liacamel's video of them spotting Martin.
The video, which was probably taken earlier on his walk, featured a noticeably drier Martin, who greeted the passing motorist with a peace sign.
