You can see from the pic how hot I got, and I’m someone who loves the heat normally.
The entire run was in heart rate zones 1&2. I really wasn’t feeling it to begin with and felt sluggish. And this was very hard work. I’ve set my maximum heart rate at 183bpm as that’s the highest I seem to have hit on my runs. It certainly seems nearer the mark, as I was able to run in the low zones, while still having to watch my heart rate from going too high.
So 50min, 4.64k, average pace 10.50min/km, max pace 6.64min/km and average HR 128bpm (though it shouldn’t have gone over 127)
It really was hot and humid. It was a relief to run along the river for a while, with a cool breeze coming off the water.
Running that slowly for that long is actually more tiring than running fast, and I was getting cramp in my left calf towards the end of the session. But something magical happened after about 40mins, and I began to feel as if I was floating along, and as if my body was in the right stance, everything flowing smoothly.
