My school put small rocks along the edge of the track for decor purposes I guess, and now I have a ton of rocks in the long jump pit. what is the best way to remove them if any?

Someone could injure their foot by landing on a rock in a LJ pit. At a minimum, you could rake out the rocks. You may need to ask for help from the school facilities department. Look into a durable LJ pit cover for the future.

Rocks often contain trace amounts of various minerals. You need a large powerful , the most powerful commercially available, magnet attached to the side of a dog. Throw a ball into the long jump pit and the dog will run into the pit and the rocks may come up.

Rocks and matchbox cars are the worst. I made a "sifter" out of some screen and 2x4's from the local hardware store. Shovel it in, give it a few shakes to let the sand through and then dump the big stuff out out of the pit. Time consuming? sure but it works. You can get automated machines but they are expensive......maybe a local material supplier has one you could rent/borrow.

Yep, I've done this too. To make it a little easier if you put the sifter on a slope gravity does some of the work for you but you have to shovel the sand up there in the first place. If you build one of these and get some kids with shovels it should go quick. There's a pretty good picture in this stackexchange post:
One of the best purchases I have made is an electric rototiller/cultivator, it is awesome for churning up the sand in long jump pits. I bought one that uses the same batteries as some of my other yard equipment so it wasn't super expensive and I've used it for a couple of yard projects too. The rototiller brings a lot of rocks to the surface and then you can rake them off, that might be enough to solve your problem. I take mine to almost every meet we go to, you can churn up the whole pit in a few minutes and then a quick rake and you're ready to go.
