List USACO Silver as an activity?

I’m currently in the application process, and was having trouble deciding which activities to put down on the common app. I only really want to put down activities that I put a lot of effort into (i.e my sport, clubs I’m president of). This last weekend I made it to USACO Silver. I’m actually not at all into competitive programming, and (luckily) passed the Bronze level. So, do you guys think I should list USACO Silver even though I don’t spend a lot of time on that subject at all?
