"Run" move action with alternate movement forms?

[Tav_Behemoth]

Is it possible for a creature to take a "run" move action and travel at 4x base speed when using alternate movement forms such as swim or flight (assuming there are listed movement speeds for that creature)?

 

[Li Shenron]

Yes.

Or more exactly...

Burrow -> NO

Climb -> NO

Fly -> YES

Swim -> YES

Thanks for the speedy answer (and the clarification), Li!

Creatures with NATURAL movements of Fly or Swim can take the Run full round action. Burrow and Climb do not have the ability to do the Run full round action.
All the actions give a note about whether they can charge/run etc.

Movement Modes: Creatures may have modes of movement other than walking and running. These are natural, not magical, unless specifically noted in a monster description.
Burrow: A creature with a burrow speed can tunnel through dirt, but not through rock unless the descriptive text says otherwise. Creatures cannot charge or run while burrowing. Most burrowing creatures do not leave behind tunnels other creatures can use (either because the material they tunnel through fills in behind them or because they do not actually dislocate any material when burrowing); see the individual creature descriptions for details.
Climb: A creature with a climb speed has a +8 racial bonus on all Climb checks. The creature must make a Climb check to climb any wall or slope with a DC of more than 0, but it always can choose to take 10 even if rushed or threatened while climbing. The creature climbs at the given speed while climbing. If it chooses an accelerated climb it moves at double the given climb speed (or its base land speed, whichever is lower) and makes a single Climb check at a –5 penalty. Creatures cannot run while climbing. A creature retains its Dexterity bonus to Armor Class (if any) while climbing, and opponents get no special bonus on their attacks against a climbing creature.
Fly: A creature with a fly speed can move through the air at the indicated speed if carrying no more than a light load. (Note that medium armor does not necessarily constitute a medium load.) All fly speeds include a parenthetical note indicating maneuverability, as follows:
—Perfect: The creature can perform almost any aerial maneuver it wishes. It moves through the air as well as a human moves over smooth ground.
—Good: The creature is very agile in the air (like a housefly or a hummingbird), but cannot change direction as readily as those with perfect maneuverability.
—Average: The creature can fly as adroitly as a small bird.
—Poor: The creature flies as well as a very large bird.
—Clumsy: The creature can barely maneuver at all.
A creature that flies can make dive attacks. A dive attack works just like a charge, but the diving creature must move a minimum of 30 feet and descend at least 10 feet. It can make only claw or talon attacks, but these deal double damage. A creature can use the run action while flying, provided it flies in a straight line.
Swim: A creature with a swim speed can move through water at its swim speed without making Swim checks. It has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. The creature can always can choose to take 10 on a Swim check, even if distracted or endangered. The creature can use the run action while swimming, provided it swims in a straight line.

xorns might be able to run while burrowing

Earth Glide (Ex): A xorn can glide through stone, dirt, or almost any other sort of earth except metal as easily as a fish swims through water
