Canterbury Park and Running Aces received permission Thursday to open their stable areas, paving the way for horses to begin arriving in Minnesota to prepare for the summer racing season. The barns at the Shakopee and Columbus racetracks are included in an executive order issued by Gov. Tim Walz, which will allow some businesses to reopen with modified protocols. Canterbury’s stables and training track will open on May 8, with only essential personnel allowed on the grounds. Running Aces will open its stable area June 1 and begin four days of qualifiers on June 10.
