I searched high and low in 1981 - couldn't find anything about the 2nd Annual Iceburg Marathon - this appears in 1982 as the "Third Annual Iceburg Marathon"

(from the Bangor Daily News, March 8 & 9, 1982)

Mark Dorian won the third annual Iceburg Marathon on Saturday in Bangor with a time of 2:42.53. The 22 year old runner from Lewiston covered the 26.2 mile route nearly six minutes faster than his closest rival, Bryant Bourgoin of Winslow. Nineteen runners, out of a field of 40, covered the entire distance.
