Alternate K's (5 K) + 100-M Sprint (5 Sets)

With Monday's training rained out,
I had a huge load of energy saved up,
so I went to a nearby park and did alternate K's (5 K)
with good marathon pace and half marathon pace being alternated one after another.
The rest after the marathon pace run was 30 seconds,
and the one after the half marathon pace was a minute.
The sky was blue and the park was surrounded with Kawazu cherry blossoms
that bloom a few weeks earlier than the famous Someiyoshino kind.

I felt hungry after covering 5 K because I did the training without breakfast,
so I thought I would call it a day,
but as I headed back home,
I felt like burning a few more calories,
so I 100-M sprints, 5 sets
with a one-minute rest between sets.

It was extremely refreshing at first, but soon I ran out of energy,
and recovering in one minute became hard,
and my time became worse after each set,
and when the last set was over,
I almost fainted with my vision all blurred
like it was covered with a thin layer of white silk.

1st K: 5:15
