Narrative:

Myself and my instructor were performing touch and go's. I announced our turn on CTAF to the left base and final of runway 15 followed with our intention of a touch and go each time. Upon landing; I retracted flaps; removed the carb heat; and applied full takeoff power. With full power set; I glanced at my engine instruments; airspeed indicator; and back down the runway. Another aircraft was taxiing to the edge of the runway; believing they would be holding short; we continued the takeoff. However; the other aircraft did not hold short of the occupied runway and began to back taxi for runway 33. At this point; after having looked down to my airspeed indicator and back outside; I decided to abort the takeoff. I reduced my throttle to idle and told my instructor I was aborting takeoff. As I slowed the aircraft to exit the runway; my instructor took control of communications announcing to the other aircraft that they had taken the occupied runway; which was met with no response other than the aircraft announcing they were back taxiing for runway 33. Upon exiting the runway; we watched the other aircraft take off runway 33 (the runway with unfavorable winds) and make a climbing left turn within the first 200 feet of the runway.I believe the cause of this runway incursion to be the other pilot's lack of communication and situational awareness. The other aircraft clearly did not pay attention to the CTAF advisories I had made; stating that our aircraft was on base and later; on final for runway 17 and indicating our intentions for a touch and go. The other pilot clearly also did not look onto the runway in both directions to notice our aircraft accelerating towards them. Furthermore; the other pilot taking off runway 33 with a tailwind component and making a low altitude departure turn indicates a clear disregard for common safety practices and procedures in the far's; aim or AC's.this incident could have been completely avoided by the other aircraft maintaining situational awareness by use of the CTAF and visually checking the runway prior to entrance. I am glad I made my decision to abort the takeoff and acted quickly (preventing what could have been a serious accident) without second guessing myself or waiting for my instructor's approval.

Title: A student pilot reported an aircraft took the runway and departed opposite direction to them as they were conducting a touch and go at RYW non-towered airport.

Narrative: Myself and my instructor were performing touch and go's. I announced our turn on CTAF to the left base and final of Runway 15 followed with our intention of a touch and go each time. Upon landing; I retracted flaps; removed the carb heat; and applied full takeoff power. With full power set; I glanced at my engine instruments; airspeed indicator; and back down the runway. Another aircraft was taxiing to the edge of the runway; believing they would be holding short; we continued the takeoff. However; the other aircraft did not hold short of the occupied runway and began to back taxi for Runway 33. At this point; after having looked down to my airspeed indicator and back outside; I decided to abort the takeoff. I reduced my throttle to idle and told my instructor I was aborting takeoff.

The other pilot clearly also did not look onto the runway in both directions to notice our aircraft accelerating towards them. Furthermore; the other pilot taking off Runway 33 with a tailwind component and making a low altitude departure turn indicates a clear disregard for common safety practices and procedures in the FAR's; AIM or AC's.This incident could have been completely avoided by the other aircraft maintaining situational awareness by use of the CTAF and visually checking the runway prior to entrance. I am glad I made my decision to abort the takeoff and acted quickly (preventing what could have been a serious accident) without second guessing myself or waiting for my instructor's approval.
