But for petty, I had these 2 kids, perhaps 12-13 run past, then walk, then run past and walk. Every time they walked, they were 2 wide, in people's way, then sin after I passed them, they would run again. Super annoying. Approaching the 4km mark i heard one day to the other "let's run all the way to the end" I thought stuff this, and let it all out for the last 1km. Ended up leaving turn well behind and ran a low 4min km. Thought I was going to die at the end.
