Row! Row! Row!
Onlookers watch Adventure Race XII participants finish the one-mile rafting portion of the race at Laughlin Southwinds Marina, Texas, April 23, 2016. Rafting was the final portion of the 28-mile race that was superseded by a 3-plus-mile run, six-foot tall wall climbs, a mud filled low-crawl, a concrete barrier hurdle and a 23- mile bike ride.
