The Long Run

The Long Run is the twenty-second piece included in the Halo: Original Soundtrack.

Overview
The piece is almost entirely percussive, with a few synth sounds in the background, which seems to resemble the John-117 running. This makes it very similar to Drumrun. It consists of a repetitive drumroll which is designed to underscore the nature of the escape and to make the player feel a sense of urgency. The piece is remastered into Marathon Sprint of the Halo: Combat Evolved Anniversary: Original Soundtrack.

Appearances
The soundtrack can be heard:
 * In the level The Silent Cartographer, when John-117 has deactivated the security facility of the island, and fights through a group of Stealth Sangheili.
 * In the level Assault on the Control Room chapter "Rolling Thunder", when John-117 rides through the tunnels of Installation 04 in a M808B Scorpion.
 * In the level Two Betrayals, at exactly the same point along the backwards journey through the same area, in the large room after the blast door which explodes on opening.
