When I was doing the C25K programme, I ran every second day ( as we all do/did) . Now, I find that when I do a 5K Parkrun , I need 2 days rest - and now that I have gotten up to 10Ks , I need 3 days before my next run.
I did 10ks on Monday morning , it's now Wednesday morning and I can still feel the "tiredness" in my legs/hips/etc. I will also only do a slow easy 5ks tomorrow morning.
You know your own body so I think you are doing the right thing and allowing a longer recovery time when necessary. We are all different and some people will recover quicker and better than others. I recently graduated and find I am more achy and a bit stiff with the longer runs. If I need an extra day, I will take it xxx
Very wise. Enjoy your well deserved rest 
Have you tried any short runs? I like to do an interval run ( I either use week1, running when you should jog and jogging when you should walk, or Speed). My legs still ache at the start, but I - and my legs - feel better for the run.
Yes -- I know it is important to have hard and easy days with sufficient time for rest in-between. I have been OK so far as I have gone -- but I am realising that, for me especially, these longer runs need both sufficient rest days and then a very easy day afterwards. Tomorrow I am going to simply do a short run of 30 minutes of simple 30second run/30 second walk routine -- and then on Saturday , I will be doing a 14 klm walk along bush tracks ( but this will be basically a slow sightseeing stroll even though it will probably take around 4 hours)
My long runs are basically long interval runs 2 minutes run/1 minute walk-- over an hour long (so far) . I am aiming to do these interval runs for up to 2 hours to complete a race in August.
I am very conscious of not overdoing things
