Tried this method and it actually works.
Took some time to figure it out, died a lot, but in the end it allows to kill multiple wolves (almost) without getting bitten.
You can't just sprint sideways though. You have to move backwards at the same time as well.
You can even see this happening in the video.
For those who are struggling, I would advise to first practice "sprint backwards" method.
Just run backwards and hit the wolf with the spear preventing it from approaching you.
It works well when you have a large linear space to run through.
Once you figure it out, add some lateral motion, which reduces the space requirement.
