We study the limit behaviour of T k f and of Cesaro averages A n f of this sequence, when T is order preserving and nonexpansive in L 1 + . If T contracts also the L-norm, the sequence T n f converges in distribution, and A n f converges weakly in L p (1<p<∞), and also in L 1 if the measure is finite. "Speed limit" operators are introduced to show that strong convergence of A n f need not hold. The concept of convergence in distribution is extended to infinite measure spaces.
