The innermost oval was originally a 7/8-mile [] grass oval until the E. P. Taylor turf course opened in 1994. It was then converted to a crushed limestone dirt course and was used for harness racing until April 2018. It was then converted back to a second turf course for the 2019 thoroughbred racing season. The first race on the new Inner Turf was run on June 28, 2019 and was won by Bold Rally with Eurico Rosa da Silva aboard.
