I ran my first half marathon yesterday. I didn’t train for it in any
calculated way, and I didn’t really plan it. After work, I checked Google
Maps for the approximate distance of my route, closed my laptop, and started
running. And although I left open the possibility of cutting a shorter loop,
or turning around early, in the end I just kept running the whole 13 miles,
just like I thought I knew I could.
上面的這句話 「And although I left open the possibility of cutting a shorter loop, or turning around early, 」
有高手能幫忙看一下這是什麼意思嗎? I left open是什麼東西.....
cutting a shorter loop 又是什麼東西...
非常感激~

看前面的語意 應該是有抄近路的可能性吧 因為他只是大概看了下地圖

left open the possibility=保留了可能性意思是他一開始估計有可能需要抄捷徑或提早折返但實際跑了之後他跑完了全程
