Welcome to HSO
Founded in 2008, Historic Simracing Organisation remains the only online simracing league dedicated to the recreation of existing races and championships of yesteryear. The well known rFactor remains our basis platform but the venerable Grand Prix Legends and Nascar 2003 are still being used from time to time.
To join one of our championships or "open" races, head to our forum ! Registrations are free for all.
