There’s also a Strava thread, it’s been quiet the last few months but the regular posters on that thread are definitely still active here on TS:
There’s a really active running thread happening now (Runners in 2023 - 5K/10K/13.1/26.2/Ultra) but I haven’t seen a dedicated cycling one in a few months. Why not start sharing here and invite people to join you? You never know, but even worst case, you’ll get some exercise, right?
