Root Explanation

Ultramarathoner → It is formed from "ultra-" (meaning beyond) and "marathon" (from Greek "marathōn", referring to the long-distance race originating from the Battle of Marathon). The suffix "-er" indicates a person who performs an action. Thus, an ultramarathoner is a person who runs races that are beyond the standard marathon distance.

Memory Tip

Think of someone going 'beyond' ('ultra-') the distance of a traditional marathon — that's why an ultramarathoner is someone who runs longer races.
