Nope, not just you.
Last few days I’ve had issues with the TrainerRoad site loading in general. Sometimes it’s slow and sometimes it takes minutes.
I haven’t yet but have been meaning to try a different browser to see it it matters. Typically using Safari.
edit: BUT I haven’t seen the “Something Went Wrong” message
Sorry all. This issue was isolated for affected athletes and fixed approx 8 hours ago.
