What is a work week like for the top teams?

I stayed in town near the race twice this past week, once on Wednesday and again Saturday night after the race. So happens several of the team rigs had parked in the empty lots in the area. I feel like I’ve always had a huge respect for all the behind the scenes work those guys put in, but it was still such an eye opener. The rigs were there idling late Wednesday night, then Thursday the guys were set up working on the bikes under the canopies. Saturday I was back in town for the race. Late Saturday night they were parked again. I assumed they were idling for the night and heading out this morn. Instead, today when I left town they were set up again and had both bikes out of the truck working. It made me think, what is a typical week in their life like? Were they preparing practice bikes today or what? Anybody have any insight or personal experience?

Now this noob will STFU
