95 miles, that's obscene! My biggest week so far is 46.2mi and I doubt I'll do any weeks beyond 50mi before the marathon.
I did a quickish long run this morning as I'm paranoid I'm actually slower than last year despite increased volume. Happy enough with 13.6mi @ 6:34/mi although I doubt I could hold that pace over 26.2mi.
That is wicked fast for a training run. You have a lot of potential if you follow some good training plans. I know during training it can feel.like you are getting slower or it can be worrying how hard a LR feels at a slow pace. Don't worry it's normal, your true potential only comes once you have tapered properly, which for most people is at least 2 weeks. I go out on my LRs at 8:25 pace last year and by mile 18 would wonder how the heck I could do 26 at race pace, but then race day comes and I hit 6:52. Good marathon training will leave you with tried legs, don't worry about speed but sign up for a shorter race about 6 weeks out,taper a little for it and use that to guage a suitable goal pace.
Doing very fast LRs like you did is OK as an occasional time trial but if that is anything regular then there is the time culprit for your shin issues or other injuries. I highly recommend you read the book 80/20 running

As for me and my millage, ended up hitting 100 miles for the week, a new PR. Weekend turned lovely, 20*C so i tacked on some extra slow miles. 100 is not easy to reach but I find 80 it pretty natural. 20 mile LR+ 15mile MLR and you are a good way there. I then have 1 quality run in the week, this week it was lactate threshold for 5 miles, but with warm up and cool down I end up at about 12 and as these.meant to be aged day I add on another 2-3 slowly at the end if I feel good. That was 13.5 this week. The rest of the runs are all shorter and slower, after a hard day typically about 8, or 6 in morning 4 in the evening. 1 of the days will be a slightly longer general aerobic f 10-12 miles.
This cycle I am pushing slightly more miles,in part for the marathon but mainly because I have an ultra coming up in the summer. Because of that I am pushing my LR to about 22-23 right now and instead of an easy 6 the next day I have used from 8-10 miles, yesterday 11, so I can get used to back to back LRs. In the summer I will end up with 30+20 double
