My wife put on 20+ miles of parking lot practice in one day before on a rebel (
air cooled) and never over heated. I doubt you will have issues.
If you need hi vis cones or something, try buying tennis balls and cutting them in half. They're generally cheap and much easier to carry around then cones. One or two tubes fit a lot of halved balls. Or cheapo colored party cups with water in the base. Visual obstacles are a great aid when you're practicing. If you're doing quick stops make sure to look up the measured distance (
if you're not using a MSF pre painted parking lot) diagram to make it easier and eliminate the guess work.
