Maybe some of your friends that don't cycle might be up for it if you challenged them. And they don't have to be your age. I ride often with my 31 yo son and personally, I hold my own pretty well with the younger folks. It helps me quite a bit when I have someone I can ride with. They don't want to any more than I do at various times.
When they ask me to go for a ride with them, I feel obligated to do so whether I want to or not. Likewise when I ask them to go ride with me they feel obligated whether they want to or not.
Sometimes just knowing that I have to ride more than them to keep the same pace or do the same climbs motivates me to do more solo rides too. If you don't have any friends that ride, then check with your LBS's and cycling clubs around you. The LBS's here usually have a Saturday ride of various groups. Some do group rides during the week to. Of course you need to get your vaccination and heed your local covid guidance.
