Itachi didn't ''run'' away from Jiraiya because he was scared as people state, he ran away because he never intended to fight Jiraiya because Itachi was one of the good guys. And he knew that he had to fight for real if Jiraiya was going to attack them because Jiraiya didn't know that Itachi was a good guy, Jiraiya would have been an unnecessary casualty as a fight could have been avoided (like Itachi did in the story by ''running'' away) Itachi is definately not afraid of Jiraiya since he didn't even give a **** about Orochimaru when he was trying to take his eyes, he's not like Kakashi who was shitting his pants when he saw Orochimaru.
This also counts for the so called ''lose'' against Gai when they also run away. Itachi said ''We've got to go before this place is crowded with ANBU members''. Itachi never wanted to fight the people he was trying to protect lolz. You kids are so dumb saying that Itachi ran away. Itachi > Gai and Itachi > Jiraiya.
MUUUUAAAD?
