Is having my story revolve around a chase boring?

My WIP story follows a company of people being chased by a character who I'd describe as a cross between a mad-scientist and a wizard, who wants to use one of the people being chased specifically as an experiment or tool(for reasons that are slowly brought to light during the story).

However, I'm hesitant because the entirety of this story is a chase. Other things happen along the way, there are moments of downtime and respite, and there is more than one constant threat to the Protagonists, but the basic plot line is all about the chase itself. Running from country to country to evade Mr Evil Wizard. Is this bad?

To be clear, I've never taken any professional writing classes or anything, so I'm not sure if this is a bland premise for a story, or if I should add any twists in to shake up the plot structure(I do have one idea, but it'd be rather late into the story.)

Sorry if this is a dumb question/should've been asked somewhere else!
