I have not done this ride in 10 years but back then there was a nice coach bus that would drive you down to Ensenada on Friday night and then pick you up on Sunday morning. They had another truck that took the bikes. The bikes were wrapped in shipping blankets and stored inside a moving van style truck. It was very nice.
as for the ride, we didn't have an elite start, my strategy was to take it really slow and easy until you hit the tiger. Then climb fast, you will leave ALL the yahoos behind. Anyone left in front of you should be OK. The only other place you need to be careful is the decent. Somehow a mountain bike always seems to get in front me, they must start hours before. They are probably in good shape but have never exceded 40 miles an hour before. So now they are going 40 on off road tires (the guys that put slicks on are OK). The tires start to float and the bike starts to shack. You do not want to be around these guys.
The party at the end is OK but the bars later that night are really fun.
I am too old for that stuff now, but it sure was fun way back when.
