The course for the Six Tunnels to Hoover Dam Half Marathon takes runners along a mountainous trail road through the hills of Lake Mead National Recreational Area to the world-famous Hoover Dam. From the starting line near Lakeshore Road, the race starts off with a big climb in the first three miles, followed by an equally big descent in the next three miles. After that, the course passes back by the starting line area and turns onto the trail that leads to the Hoover Dam and back.
