Dance II. Larry Kohls, CYC. CHA 70. 1983 Chicago to Mackinac Race. IOR Section 1, rated 53.5.
Of course, the SuperMacs were longer and there may be other races that lay claim to being the longest,
but CYC often used this description, accurate or not. And I think 'annual' may have been part of the description,
now that I think back.
Larry, you are right that Annual was part of the description because not only was the irregularly scheduled Chicago to Sarnia longer but the biannual TransSuperior is also longer. It took me years to get out of the habit of referring to the Chicago Mackinac as 333 miles (statute) and discussing it as 289 nautical miles so that its length could more accurately be compared to the other classic races around the world.
