Burning lungs. Leaden legs. Pouring sweat. Why is anyone crazy enough to be drawn to running a race? Why is it such a timeless pursuit?

There’s an excellent quote from the book Born to Run that’s hard for any runner to forget: “The reason we race isn’t so much to beat each other… but to be with each other.”

At nightfall at a Tijuana state penitentiary, a protest is breaking out. Prisoners, mistreated and forgotten, grow increasingly violent, until the protest is a full-scale riot. Police spill onto the scene immediately. A SWAT team soon follows. None of them can quell the inmates’ anger.
