what is the difference between "real time" and "quick timie" in a marathon?

Answer 1

I've never heard those terms, but I'm guessing it refers to the difference between clock time and chip time.

Runners in large marathons wear a computer chip on their shoe that records when they pass the start line, finish line, and checkpoints on the way. When there are a lot of people at the start, it can take you several minutes to even cross the start line. This time is subtracted from your total time at the finish to get your chip time. So when you cross the finish line, the clock may say 4:30, but it took you 5 minutes to get to the start line so your chip time is 4:25.

Its important because clock time is used for the elite runners going for first place or world records, but chip time is used by average runners who just want to know how long it took them to finish.
