Only in Vegas

So you’re running in the Zappos.com Rock ‘n’ Roll Las Vegas Marathon and, as you pass the Riviera, your hamstrings burning you like a Donald Trump real estate scheme, you have a sudden urge to lay some bread on that night’s Detroit Lions vs. New Orleans Saints game. You’re in luck … or in Lucky’s Race & Sports Book, more accurately. When Lucky’s sublicensed sports-betting operations at the Riv, it added a walk-up betting window, of which two Colorado runners (pictured) took advantage. You can’t make a quickie wager on the Red Sox during the Boston Marathon, can you? Well … not yet, anyway.
