The game uses past results from sites like UltraSignup and UTMB Index. Players earn up to 500 points for a first-place pick. For top-ten contests, the maximum is 750 points. Weather and personal challenges can affect outcomes. Read more racing coverage.

Freetrail’s tech head, Travis Loncar, built the system. The team updates the elite roster before each race. Players should consider course style and runner consistency when making picks. Related: Hunt Wins European 100m Gold, Britain's First at Championships.
