Marathon

by Neal Tibrewala

Answer:
TOE DRAG

Together with the names of the winners and “marathon” we’re meant to think of “movie marathon” and the names of famous actors. Checking their filmographies, we see that each actor has a movie with an ordinal (nth) in their title: for example, Sylvester Stallone acted in First Blood.

We can also group the given items into 7 groups of 7, each related to the other word in the movie titles. The items are given in a specific order. Taking the nth item from each list, we can read the first letters in order to get the answer TOE DRAG.
