Nike NYC Race Day Mile 21 Challenge

The Challenge starts and ends based on each participant's local time zone. Manual entries, [virtual runs, treadmill runs] will not count towards the challenge goal. Activities must be marked "Everyone." All activities logged during the Challenge period. You must cross through the segment start, continue on its path exactly as it was created, and cross over the segment finish in order to match. Once you've started the segment, you may not deviate from the segment's path whatsoever. In other words, stay on the segment. You must complete the segment in the direction it was created. You can not complete it in the opposite direction. If the segment is a loop, you must start and end the loop at the segment's designated start/end points. You may not start and end the loop on another part of the loop, even if you completed the entire loop. Avoid resting right before or right after the segment, because this resting time may get included in your segment time and we will not adjust your match to remove this time. More info here. Make sure your device indicates that you have a strong GPS signal prior to recording. If your device does not have a strong signal, the GPS data may be offtrack from the segment and this may cause you to not match that segment. The description of this challenge is provided by Nike.
