<p>I know some people love the Keys 100/50, but it is on Route 1 in traffic. And there is no aid; you have to have a crew that provides aid like Badwater. And you have to contend with the 7 mile bridge, where you would be without aid on a bridge in traffic for 7 miles. But the last time I was in the Keys I did see the mile markers and think it would be cool to run down to Key West (before they started the race). I can see the allure. </p>
