I'm the exact opposite of you. I didn't begin seriously training until I turned 31.
Just get out there and do it.
I see what you are saying and glad that you are having improvements. That said, you began training hard at 31 it's much easier to be excited about the sport at 31 when you are new to it and PR's are relatively easier to come by.
Someone who is 30 who has been running 65+/- halfs or Marathon equivalent has probably been training very hard for 12-14 years and is also realizing the PR's from their mid to late 20s are hard to come by when you have family, career, more money, better quality of life, and other fun hobbies to pursue.
They also realize at that point that they've been to some USA Road Championships, been invited to cool races, won some prize money and had their share of local fame.
At this point, you are still working hard putting in 0,90,100,100+ mile weeks, hard workouts but instead of hitting a great race 3 out of every 4 its more like you have a good race, then a few shitty ones in a row even with the same work because you can't recover like you used to because you don't slack off at work or take lunch time naps or are a spry 25 year old. It can be hard to stay motivated.
I think that is more what the OP is going through. I myself am going through something similar. Was an All American in College, did the post collegiate thing team thing. Did the I have a real job, train by myself and have a shoe sponsor thing race well thing. You've worked hard at the sport your whole life, you have talent, used it well, but are realizing the first signs of burnout - especially if you never had a break. You still love the sport but the energy it takes to compete at that level is sinking in for the first time..
I had this happy recently recently. My current decision, and advice to you OP is this. Take a small break. 3-4 weeks. Run when you want, stick to the trails do what you like. Maybe ride your bike, lift weights, hike, whatever. At the end of the short break ask why you like running and start running if there is pleasure in it for you. If you find the spark, great. If not, well stay fit and be at peace with departing but move onto a new chapter of your life with the same intensity. Good Luck!
