There are novice strongman comps by weight class that you can enter that would scale the atlas stones and adjustable hussafell stones.

This is an example from a UK gym that I know holds lots of comps. Scroll down for the novice/beginner comps.

Note also that is not unheard of for people to "blank" i.e. not complete any reps of a particular event. It's often said that if you don't (particularly at the lower levels) you're not challenging yourself.

It's also bad form to enter a novice comp if you already have a 300kg deadlift.
