Fastest segment times on alpe du Zwift

Are the best segment times only counting when you participate in an event, or also when you ride a route like route to the sky, my best time in zwift power for alpe du Zwift is 1 hr 8 min
but yesterday i did 46 min. 15 sec. and the week before 57 min. 51 sec. they are both listed in my activities in Zwiftpower

thanks in advance

Only you see your basic “activities” . Others see only the official “events” you complete as rides, races, and group workouts. So, if you rode an event like the Tour de Zwift Stage 3, then it will be listed and counted as your best time. If you rode in a personal ride or workout, then it does not count in your points as a racer and others can not view ZP.
