UltraSignup Race Visualizer

See how a runner’s finish time compares with the field on UltraSignup, with a histogram that follows age and division filters.

See where your finish fits in the field. UltraSignup Race Visualizer adds a finish-time histogram directly to supported UltraSignup results pages. • Select a runner to highlight their finish-time interval. • See how many other finishers they finished ahead of, with ties counted separately. • View finisher counts and median finish time. • Compare groups using UltraSignup’s existing age and division filters. • Open an accessible table of the distribution counts. Results are processed locally in your browser. The extension makes no additional network requests and has no accounts, analytics, or tracking. Supports individual, fixed-distance races on UltraSignup’s desktop results pages. DNF, DNS, disqualified, unofficial, and invalid finish times are excluded. Restricted or unsupported results display an explanatory notice. Built by an ultrarunner for the running community.
