A spectacular crash marred Southland's biggest day of harness racing at Ascot Park in Invercargill today.
The race-10 crash is thought to have been triggered when Louie, driven by Tim Williams, faltered through injury and crashed to the track about 50m past the winning post.
Several runners behind were unable to avoid the stricken pair and crashed over top. Williams said the incident happened so quickly it was difficult to establish exactly what happened.
''When you are going at that speed ... it happens that quick.''
Ambulance personnel and others went immediately to the aid of the affected drivers.
