Your experience with the Continental 4000's has been my experience as well. That would have been my tire of choice doing a XC ride like yours. And I've had the same experiences with alcohol products. When you combine it with my poor habits of drinking too little fluids during a ride it's just not a pretty outcome. Looks to be a little muggy today but hopefully the weather will steer clear for you. Should be a fabulous day to bring that rascal home though.
