A slightly oddball idea for a run course: there's a 5k in Asheville, North Carolina (at least vaguely familiar territory for me) this weekend, whose purpose is to draw attention to a particularly egregious Congressional gerrymander. The run follows
one of the more convoluted sections of the electoral boundary which splits Asheville in half.
If you're wondering why the boundary-drawers might want to do such a thing, Asheville is, I believe, the only place in the entire Appalachian region which voted for Clinton over Trump, and the idea is to split it into two so the two halves are each swamped by Republican votes in the boondocks.
(Quite a few of my runs follow electoral boundaries, but that's because the Yarra River and Merri and Darebin Creeks have both good places to run and form boundaries of electoral districts).
