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, plus the vector of the weight and the climb angle.

Gliders that have stalling speeds below 40 knots in free flight often
start buffeting and feeling slightly out of control if they are flown much
below 50 knots on aerotow.
