VDOT Training Day 2 - Quality Session (Repetition Running)

On the second day of VDOT training, the Quality Session was conducted.

I didn't know why the runners wear a singlelet, but now I want to buy another one.

Quality Sessions are high-level training sessions, including Interval Running, Repetition Running, and Long Running, with the exception of Easy Running.
Every Tuesday, Thursday, and Saturday was planned for a Quality Session, and according to the original plan, we had to perform Interval Running today.
However, I wanted to experience the V.O2 app that is currently in Free Trial, so I trained Repetition Running according to the plan I set up in the V.O2 app.

Repetition Running is a training that repeats running and recovery at a slower pace than Sprint but faster than Interval Running.
The purpose of this training is to improve speed and economy, which is said to be. It's different from Interval Running, which improves VO2max to increase aerobic capacity.
Started the first Repetition Running after the 2.5k warm-up.

irregular pace

In my case, 446 pace is moderate, but initially 353, then 414, 433, 455, etc. It only slowed down after the overpace.
I didn't get a good idea how much the 446 pace was.
Anyway, I finished 4 high-intensity drills and finished with a 2.5k cool-down.
I woke up relatively late today and ran in a hurry. As a result, it's a pity that I couldn't stretch properly.
For leisurely and healthy training, I should take early wake-up as a habit.

The interface of the Apple Watch basic exercise app is convenient,.
