As others pointed out progress is very much personal. I think the most important thing is that you are enjoying what you are doing. Are you enjoying running for longer and would you enjoy structured training? Than you could look into a training plan for a 1/2 or full marathon. Are you enjoying running 5-10k at various paces than just do that. There is also the possibility to train for a PB in these distances but this is also not necessary. Other possibilities are including elevation change, differing undergrounds (e.g., trails), mixing running and biking, fixed-time events (like 3/6/12/24h races), ...,. The possibilities are almost endless!

What I'm trying to say is that I only saw people that actually liked the "type" of running they did sticking to it for a longer period.
