Traffic practicing instrument approaches to runway 5 at CGZ is very heavily congested. Due to this reason; the local operators have established that runway 5 should be used up to a 10 knot tailwind to accommodate the approach training. As such; winds were 210 at 7 knots; we taxied to runway 5 for our departure making radio calls on CTAF regarding our taxi; then following our run-up and then prior to taxiing onto the runway for departure. The only radio calls other than ours on the frequency were made by aircraft practicing the approaches. We checked final and looked to the other end of the runway as we taxied on and saw no other aircraft. After aligning with the runway it was difficult to see the far end of the runway clearly due to high temps on the runway creating wavy distortions at the far end from rising heat and as we began to apply throttle for takeoff suddenly we began to notice the shape of an aircraft rolling opposite direction on the runway. We reduced throttle to idle and exited at the first high speed and the other aircraft exited well down the runway. That aircraft made no radio calls to CTAF and multiple attempts to contact him were fruitless. It appears he was making a high speed taxi on the runway or using it to relocate to another area on the airport as he was never seen on final. Further vigilance will have to be made in such a high traffic area but it is important to continue to spread the word regarding local procedures at this airport and it really seems that radios should begin to be required at all airports for the sake of safety with how busy the airspace system is these days.
During the takeoff roll a general aviation pilot encountered another aircraft taxiing opposite direction on the same runway. The pilot rejected the takeoff; exited the runway; and attempted to contact the other aircraft to no avail.
