<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">runner'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 "Strip of material (that might be red!)" , "The winning runner breasts the ...." , "that race winner may break" , "Adhesive strip; record" , "Common medium for recording" .)
