you either need to have store experience or have a great running resume along with a solid academic resume. you have to ask yourself "What do I have that no one else applying for this job will have, that will make company X want to hire me?"
if you have multiple All-American certs from a D-1 (preferably) school, then that's a good in at any company for tech job or even just an internship....which can lead to a job. if you don't have that, then you need something unique. i know the nike guy who was in NYC a few years ago had run across the united states.
if you don't have anything to set you apart from others, then you likley need to work in a store and build a really solid base of running tech knowledge.
