Some good quotes:
"When I'm on the trails, time goes faster than when I'm on the road," said Soler, 47. "It's just the distraction of nature and the footing. You have to think about where you are going. It takes a little more work, but it can be very rewarding."
"It's an invigorating, refreshing way to be out in nature," Jacob Rotich, 29, said after completing the Prickly Pear run. "Out in the woods, away from the cars, it's pure oxygen. It's quiet and nice. You can almost meditate."
