RIde Ons After your Event

Why is it that after my event I receive Ride ons?. Is it possible to go into the group ride and give ride ons after the event has finished. I feel that I’m not returning the favor as much as I should. Even riders who are not in my ride manage to give me Ride ons. Could someone help please?

You can give people Ride Ons from the Activities list in the Companion, or from my.zwift.com.
