PHOENIX — Obstacle course runners start on their feet, but eventually end up on their stomachs, sides, even backs at they clamber through mud, over shipping containers, across netting made of mangled ropes.
The most mentally strong will choose courses where they have to jump off large platforms into water, run across fire, even crawl through water as live wires zap them from above.
Sound like fun?
OK, burning and shocking may not be for everyone, but not all obstacle course races are that intense.
