RaceWorth puts 45 ultramarathons on a Demand × Worth board

Field notes

The homepage organizes 45 destination ultras into a five-by-five Demand × Worth grid, with Demand increasing down the page and Worth increasing across it. Each race is represented by its name in a score cell, while individual cards provide the listed ratings and source-backed write-ups. The methodology describes ten scoring dimensions, and the site deliberately retains low-Worth entries such as Leadville Trail 100 and JFK 50 instead of presenting only favorable recommendations.
