Conversely, I run better first thing in the morning (or at least an hour after porridge!). I'm usually tired in the evening and it always feels like hard work.
2 x 9 miles is very nice work for a weekend; sounds like training is working well.
Its time for me to extend my long run at the weekend in prep for my april marathon. I must admit I don't really enjoy the 20+ milers....
Cheers
Evenings don;t work at all for me. I may be tired in the morning but after a mile i am really in the mood. And it is much more motivating running into a sunrise.
I also like the fact that you can spend the rest of the day slowly working out your muscles and loosening them up. If you run in the evening and go to bed soon afterwards then muscles will be extremely stiff.
The other thing is simply planning and ensuring you have time to run.If you run early then there is less chance of any work or unexpected meetings/family crisis creeping in. Nothing worse than hoping to do a run and then your boss asks for a document at the last minute or kid gets sick and you have to pick them up form school.

I love Long runs, but I can be somewhat apprehensive about them. It helps to be nice and fresh, so no hard workout the day before, go to bed earlier, no alcohol night before. Eat a bigger carb filled breakfast, have a nice treat like donuts. Don't think about running 20 miles, break it up into smaller chunks of 4 to 5 miles, these are stages of the LR and you will feel slightly differently through each stage. Make those first 4-5 slower than your easy pace runs, more of recovery pace. A gentle warmup that just ticks off a few miles. You should then feel really good and fresh, if you don;t then do another 3-4 very slow miles. Then in the next stage speed up each mile so you end up running at your regular easy pace to slightly faster. You want to hold that pace for 8+ miles then you can think about how strong you feel and how hard you want to push yourself. If you are suffering massively then just call it quits and finish on 16 miles or whatever without breaking yourself. If you feel good enough then try and progress those miles, start taking 10 seconds off a mile. Keeping progressing slightly until say mile 18 or 19 then relax back down to easy pace to finish off.
The easy start should see you over the miles without issue. The change in paces at each stages helps the miles tick by. The progression at the end builds mental strength and endurance, simulates a marathon and makes the miles go quicker when you feel bad.
If you easy pace in 9min/mile then the first quarter could be at 10 minute pace, perhaps starting at 10:20 and ending up 9:30. Then speed up to 8:45 to 9:00 pace for the middle. Then if strong working down to 7:45 a mile, maybe 7:20 or so penultimate mile, then back at 9 for the last mile cool down and flush legs.
