In 2006 the race format changed significantly with the addition of a Solo Enduro division, in which riders were obliged to rest off the bike for a total of 40 hours at specified points across the country. The 40 hours were to be deducted from a rider's total time at the end of the race. These changes were made to improve safety and shift the emphasis to long-distance riding speed and away from the capacity to endure sleep deprivation. Because the intention was to phase out the traditional format, it was announced that henceforth the official RAAM champion would be the winner of the Solo Enduro division. In the first year the winner was 50-year-old Jonathan Boyer, who had won the fourth edition of RAAM twenty-one years earlier. However, interest in the Enduro format rapidly faded among riders, and the division was soon eliminated. The official RAAM champion is now the winner of the Solo Traditional division, which simply measures total elapsed time from west coast to east coast.
