Let hope he heat does subside BUT...... either way, it's a very good idea to start your hydration process a couple of days prior to the weekend. Fluids need to get into the body ahead of time, not just the day of the event(s).
Parents, get with your kids and let them know what they need to do to prepare for the weekend and possible high heat. You Rotaxians, you all have some extra laps to run. Hope you're ready...
Now.... LETS GO RACIN !!!
