Narrative:

During a training flight; our aircraft was in a right hand turn to the northwest at 4500 MSL a couple miles west of the airport. The PIC trainee (pilot not flying) was loading approaches in the FMS while I was the pilot flying. My time was divided between normal monitoring; outside scan and instruction on the FMS while heads down with the pilot not flying. Almost out of the turn; I looked up and saw a co-altitude glider approximately 500 ft away; pointed toward us at my 2 O'clock position. I took no evasive action since we were not on a direct collision course. However; we passed within approximately 200 ft laterally at the same altitude. The glider pilot apparently saw us about the same time because his bank angle increased to 45-60 degrees. There was no radio contact with the glider on CTAF (which we were monitoring).
