אֲנִי נֶהֱנֶה לָרוּץ כָּל בֹּקֶר http://www.nakdan.com/Nakdan.aspx
Why not: I enjoy to run every morning
Well, the verb enjoy only accepts verbs in gerund form after it.
Because it's incorrect English. See IngeborgHa14's answer.

Perhaps this should accept:
I like to run every morning
I enjoy running each morning - correct translation.
