Running shoes for SFAA : Road Shoes or Trail Shoes

[angel]

I was wondering if I should take road running shoes or trail running shoes to selection.. im trying to get every inch I can on preparation.. if so any you recommend.. as of now I got some Nike Running shoes.. But looking for any suggestions, tips, and knowledge you guys might have..I've heard the runs are on gravel or some kind of pact sand.. wondering what you would wear for that kind of run. Thanks again for your time
