Ultra Running Hub is an online resource for ultra runners, bringing together race discovery, training guidance, and gear information in one place. Its searchable race directory lists events worldwide, with details such as distance, location, elevation gain, format, and date. Runners can browse by distance or terrain and use the site’s Grit scale, which combines distance and climbing to indicate the demands of a course. The score is shown only when sufficient elevation information is available; the site does not infer missing data. Athletes can also enter recent training volume to calculate an athlete Grit score and find races suited to their current fitness.

The site publishes training plans for distances ranging from 50K to 100 miles, along with race-specific preparation articles and guidance on nutrition and race-day fueling. Its curated collections highlight themes such as alpine classics, desert races, and fast 100-milers. Gear pages feature trail-running products, including shoes, with descriptions, prices, and review-based ratings.
