An Update on Who Raced All Three? – Kenny, Kenny Jr. and Kurtis

Ascot Half-Mile results from 1977.

Mike Sullivan is one of only four riders I can find who have raced all three Robertses - Kenny Sr., Kenny Jr. and Kurtis.
This past January during an interview with longtime racer Mike Sullivan, I wondered out loud if he might be the only rider to have raced all three of the Robertses in a national. I and a couple of other racing historians started doing some research and we came up with just three riders, Jimmy Filice, Bruce Lind and Rich Oliver who definitively raced Kenny Sr., Kenny Jr. and Kurtis during a national road race or flat track.
At the time Sullivan told me he thought he’d raced all three, but wasn’t sure when, or if, he’d raced Kenny Sr. Well thanks to Sullivan being a packrat he has dug up info proving that he did race Kenny Sr. at Ascot back in 1977.
