Everything is good

I did the workout in the morning and as far as I can tell no ITB problem.
I have not even fell any tingling today (yet. I know it is only noon...), which is great. So seems it was just a false alarm on Saturday morning.

Although ITB feels good, I feel blah.
Now I know why I liked 1k repeats so much (although I have suspected it for a long time)- it is because I have always done them slowly (that's also the reason why I always managed to hit my paces), not at my true 5k pace, so it was easy for me. According to my time from last Sunday, my 5k pace for 1k is around 3:47, and I have done my workouts at 3:53-55pace and then usually hit negative splits to run a bit faster.
Therefore, past two weeks when I did my workouts at 3:45 pace were HARD. Really. But that's what is going to help me progress, right?

Today I did
4k sub-tempo at 4:19ish pace (17:17) and then 5x1k w/ 2min rest (I cheated on the last one because it was just too hard).
I did 3:44, 3:44, 3:44, 3:43, 3:42. Before the last one, I did not jog for 2 min, I walked 200m to the start so it was 3min break.
First 2 repeats went ok, pretty easy but then it started to get harder and harder. Both my legs and arms got tired. (I should start to do some arms exercises. When I was younger we would do 1minute "arm drills". 1min circles with one arm, then change, then both arms, then movement you do while running and so on. Maybe it will help.)
And the 4th and 5th repeat- I was working hard on those.
Times are faster probably not because I ran faster but because it was very windy on straight sections of the track and after 3 repeats I decided to change my start so I run 3x with the wind and only 2x against the wind during those 2.5 laps. Or maybe I ran faster:) Because there was this guys that little started before me and I told myself to catch him and I did and then he stayed with me, so we pushed each other. Too bad it was the last repeat. We could have run together.

Conclusion: 1k repeats are not my favorite workout anymore. I will choose something easier as my favorite workout.
