Hilly Group Rides

Does anyone know of regular hilly group rides? Most of the rides I see, and sign up for, are flat. I see the hilly rides but not training or social rides (I ride D or C). Thanks in advance

Look for hilly routes on https://zwifthacks.com/app/events/.

Here are a couple:
Ascenders Team Midweek Ride The at Home Cycling & Running Virtual Training App
Roll with Castelli - Climb Time The at Home Cycling & Running Virtual Training App

Thank you - new resource - awesome!

Thank you!
