Big Warden — "Biggie" around the barn — is a 17.2-hand Ontario-bred Thoroughbred by Big Screen out of Executive Affair (by Bold Executive), bred by Spring Farm. He made 22 starts with 3 wins and $72,703 in earnings before retiring from racing in early 2025; his last start was January 8, 2025 at Parx Racing.
Mackenzie restarted Biggie off the track and brought him along for the 2025 Retired Racehorse Project Thoroughbred Makeover at the Kentucky Horse Park, presenting him in the Field Hunter division. He has since found his next rider — one more Thoroughbred produced and placed through the program.
