1. An extendable ladder having a collapsed mode and an extended mode, the extendable ladder comprising:
a plurality of sections that are slidable relative to one another, each section of the plurality of sections including two stile sections and at least one rung extending therebetween; a hollow elongate housing secured to respective lower ends of the two stile sections of a lowermost section of the plurality of sections; at least one ground stabilizer mounted in the hollow elongate housing and movable between retracted and extended positions, the at least one ground stabilizer projecting laterally from the hollow elongate housing in the extended position so as to widen a footprint of the extendable ladder; a spring urging the at least one ground stabilizer into the extended position; and a locking pin mounted to move with an upper section of the plurality of sections and retain the at least one ground stabilizer in the retracted position when the extendable ladder is in the collapsed mode, and to automatically release the at least one ground stabilizer when the ladder is moved into the extended mode, such that the at least one ground stabilizer is urged into the extended position by the spring.
