Hill Intervals: 10 Sets by 1 K

Today is my last day off before Kyoho no Oka 20 K Road Race 2017 that is scheduled for this coming Sunday. It's my last chance to do a long practice run.
I had two choices in mind:
1) Going for a 25 K run at a comfortable pace
2) Doing hill intervals
I chose 2) because it would take less time, but intensity is higher.
I originally aimed for 7 sets, but when all seven sets were completed, I thought I could go for one more set, so I did eight. But when the 8th set was completed, I thought two more sets and I would make ten, which made me want to do yet another set, so I hit the road again. When the 9th set was over, I was a zombie that didn't know how to walk. But I mustered up all of the energy that was left in me, and hit the road again for the 10th set. Each step felt like a nail in my leg. Lactic acid building in my legs kept them from moving at my will. Breathing became difficult with a tiny increase in pace. Slowing down made me feel miserable. I wanted to cry. But with each step the goal came nearer. The last long upward incline looked like a giant wall that stood before me. My body felt heavy as if I was being pulled from behind with a strong rubber band. My soles felt sore in my minimalist shoes MUTEKI. My head pulsated as if it was on the verge of explosion. The hill was finally over. What remained was a short stretch less than 100 M. I tried to surge, but lactic acid in the legs didn't allow me to. I gasped for air, shaking my head from side to side in an effort to increase the pace. The next moment I reached the lamppost that marked the goal. Mission accomplished!

I jogged back home and took a shower. I felt two pounds lighter when I got out of the bathroom.

The laps sucked, but I did everything that I was able to do at the moment. I'm satisfied. Today's result is shown below. It's very bad, but I can live with it. My next training is going to be very light. It will be 3 to 5 K at the most. Pace may be a little brisk just to stimulate cardio, but I don't want to be too fatigued. I want to be in best shape on the day of the race. No more long run. No more intervals. I did them all.
