Marathon


 * For the Call of Duty 4: Modern Warfare challenge, see Boot Camp (challenges).

Marathon is a new perk in Call of Duty: Modern Warfare 2 that gives the user an infinite sprint duration, replacing the Extreme Conditioning perk. The Pro version of this perk is unlocked after running 26 miles and allows the user to vault obstacles faster. It is one of the first perks in Create a Class.

This perk is unlocked at the start of the game.

Pro Version
The pro version of Marathon is unlocked once a user has sprinted 26 miles across all games while it is equipped. The pro version allows you to climb ladders and vault over cover more quickly. Aside from the obvious increase of action speed, your sprinting isn't affected by the perk.

Trivia

 * The way to get the Pro version is a reference to a real life marathon, where runners race a 26 mile course.
 * There is also a challenge in Call of Duty 4: Modern Warfare and Call of Duty: World at War called "Marathon," which is completed by sprinting the same distance of 26 miles.
 * The perk's picture is very similar to the Extreme Conditioning perk's in Call of Duty 4.
 * This perk, along with Lightweight and SitRep, are considered some of the hardest to acheive the VI Challenge for.

Tips

 * It is useful to have this equipped with Lightweight, as completing the perks' challenges both include sprinting for a certain distance.
 * You can cheat by sprinting up against a wall continuously rather than sprinting around the map, a much more hazardous method.
 * In Capture the Flag, where running is needed, this is good, as you never need to walk.
 * This can be useful when trying to run to a popular camping position, as you have the speed advantage.
 * This perk, coupled with Lightweight, can be incredibly useful in Search and Destroy modes, to rush the enemy spawn. Lightweight can make the process even quicker.
 * With Lightweight it is great for capturing flags and rushing back to defened them in Domination
