10K, workout #37

Today is hill sprint day.

The workout

I'm doing 10 times 400 meter hill 'sprints' (sprints are typically shorter) in a bicycle tunnel near my house today. Slowly running down to the start is recovery.

Afterwards

I was used to doing this workout, but with 'only' 8 times 400m. 10 was okay, but muscle fatigue, especially in the upper legs, does strike after 6 or 7 intervals. Oh well, in for a penny, in for a pound. The intervals felt good, but the tunnel floor was wet, so it was kind of slippery, and my shoes squeaked like mad.
