I was in the same situation last September, trying to get from CR to RPDE at the speedway.
Petty runs a shuttle between the TTC and the track. They have a parking space right in front of the kennel marked with their sign.
I just took the monorail from CR, walked down the ramp at the TTC and waited for the van to come get me.
I was running the early morning session and traveling this way got me there in plenty of time.
You might want to bring the track phone number and a cell phone just in case you need to remind them that you're waiting for a ride.
Lemme know if you have any more questions that I might be able to help with.
