Remember that a glider has to produce more lift when climbing.

Why?

The glider does not just get pulled up by the tow rope! The tug acts as a
remote power source so that the glider can climb through the air without
losing speed. The wings have to produce more lift to support the weight of
the glider...

How big do you think that effect is?
