EDMONTON, Alberta – Speed, and which horse will be able to carry it going around four turns, seems to be the theme for Saturday’s Grade 3, $300,000 Canadian Derby at Northlands Park. The 1 3/8-mile feature attracted 10 horses and headlines a strong 13-race card that includes the $75,000 Speed to Spare for 3-year-olds and up and the $75,000 City of Edmonton Distaff for fillies and mares. Post time for the derby is 3:45 p.m. Mountain.
