I've seen a few of these pop up on my Facebook feed. Do they have a place in the future of running? If they encourage people to get off the couch, I hope so. With these and mud runs/warrior dashes, maybe we can get some people active who otherwise wouldn't be. That said, I sure hope there will always be a place for traditional racing.
I believe the sport is big enough to support all types of runners and all types of events. Hopefully, these events will not prove me wrong.
