Thousands of runners will take to Utah streets this Saturday for the annual Salt Lake Marathon. The spring time event also draws thousands of spectators and tends to catch some motorists by surprise.

In this segment, Maria Shilaos gets details on the marathon itself -- including what makes it special and which roads will be closed for the race -- from Jennifer Nelson, marketing director at High Altitude Special Events, which oversees the marathon. She also speaks with Olympian and Utah State University alum Chari Hawkins, who's serving as this year's Grand Marshal.
