"Who Will You Run To" is a song recorded by American rock band Heart. It was composed by Diane Warren and released as the second single from Heart's ninth studio album Bad Animals. It is an uptempo rock number in which singer Ann Wilson warns a departing lover that there will be no one else who could care for and support him in the way that she has.
"Who Will You Run To" is one of a long list of hit songs written by Warren, who is one of the most prolific and successful songwriters of the 1980s and 1990s. Heart's version of her song became the band's eighth U.S. top-ten single, peaking at number seven.
It also climbed to number thirty in the UK Singles Chart, where it was also available as a 12" single, and also as Heart's first UK CD single release, featuring an extended 'rock' version, running at 5:05.
