Two or Three-Person Relay Team

Not ready for the whole enchilada by yourself? Pick a teammate and tackle the two or three-person team competition. Each rider strategically chooses which loop they want to ride and races them relay style. The Two-person team races the 60 mile Marathon course, while the Three-person team races the 92 mile Ultra course; each racer does one of the two or three loops in order. Teams start with the solo racers and enjoy the beauty of this spectacular  course without quite as much suffering!
