Human Factors; Procedure
I was waiting to depart ZZZ. I was monitoring inbound traffic visually; via ADS-B; and over the radio to determine an appropriate opportunity to depart. One aircraft had just landed. Two aircraft on downwind were discussing the spacing between them. One of them decided to do a 360 for spacing. One other plane was 8 miles out on a straight-in. After the plane that had just landed exited the runway; I continued tracking the two aircraft on downwind; listening to their reports on the radio and via ADS-B data on a moving map. I could see no one on final or base.Just as an aircraft reported turning on left base; I radioed that I was departing XX with a left downwind departure while taxiing onto the runway; and started an immediate takeoff roll. Immediately after my transmission ended; the same aircraft that had just reported turning base reported 'turning final' followed by 'coming over the top; watch out;' while another aircraft transmitted 'aircraft taking off; there's a glider landing on top of you.' During that exchange; I aborted takeoff to clear the runway as soon as possible. I also transmitted that I would vacate the runway as soon as possible. The glider flew high above me and touched down on the second half of the 7;000 foot runway.
C172 pilot reported a ground conflict after beginning the takeoff roll at a non-towered airport.
