<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sprinter's goal</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tape that I've seen before include "String to be broken at end of a race" , "Record; cassette" , "that may be red" , "that race winner may break" , "broken by fastest runner" .)
