Marathon Runner Tracking??

[cewait]

They're your elapsed time when you cross timing mats at various points on the course. Usually every 5 kilometers and also at mile 13.1 and mile 20.

Slight correction for Disney....

Half - 5, 10 and 15k
Full - 5, 10, 13.1 and 20 miles

I wish D would run a 5 k split at the full. It's much easier to track where one is in the race on a 5k split
