What is everyone's experience with accuracy of their watches? In smaller races the Nike is almost right on with distance and pacing but falls off in the Disney marathon, likely to the large crowds being unable to take the shortest line, etc., i.e. 26.64 miles on GPS for Disney marathon
Paces compared to the chip times:
0-5 mi pace, GPS was 0:13/mi off
5-10 mi pace, GPS was 0:11/mi off
10-13.1 mi pace, GPS was 0:13 off
13.1-20 mi pace, GPS was 0:03 off
20-26.2 mi pace, GPS was 0:14 off
