This is a parody of an Old Master Q (Lao Fu Zi) comic featuring various MLP characters including Rainbow Dash, Flitter, Cloud Chaser, and Derpy Hooves….
 
Original Comic
 
Rainbow Dash: “Derpy, how the heck did you end up taking the baton from Cloud Chaser’s team and not our baton??”
 
Derpy: “Uh… I don’t know what went wrong…”
 
Rainbow Dash: sigh “Either way both our team and Cloud Chaser’s team got disqualified…”
 
note:  
-Other than Rainbow Dash and Derpy, the other runners involved are based on the background pegasi… I forgot the names of those other two I added in…  
-This comic was drawn while the Olympics were still going on…
