I had an amazing experience of biking thru the Red Rock Canyon. At first, I was surprised to learn the first 5 miles went uphill. I gave it a try and then decided to ride in the van because my legs were shaking! I rode about a mile in the van and then got out to bike again. Went further this time but rested again when the climb was really steep. When the van reached the peak, I got out and rode the rest of the 10 miles. Most of it was downhill but there was a "wall" and then another crazy hill. I rode for about 6 miles without seeing another biker or the van. I was totally alone out among the rocks! Finally I spotted a traffic jam of cars and rode closer to see 6 burros by the road -- Just standing there having a good time. I rode on and finally spotted some bikers and a van way down the hill. There was the group of bikers! We waited about 15 minutes for the final rider and the backup van to appear. I may not have rode the whole 15 miles (since I sat in the van for two-three miles), but I made it to the end! Yay!
