"Marathon" is the fourth track on Canadian rock band Rush's 1985 album Power Windows.

[2] The lyrics depict how one would feel while running in an actual marathon, but the meaning of the song is meant to use a marathon (an extreme challenge) as a metaphor for life, and say that life is full of obstacles and is all about one taking small steps to achieve their personal goals.

And it's also about the old Chinese proverb: 'The journey of a thousand miles begins with one step.

"[3] The live version released on the "A Show of Hands" single reached number 6 on the US Mainstream Rock chart in 1989.

Power Windows is perhaps Rush's most heavily synthesizer influenced album.
