Interested in analyzing racer performance, or want to include checkpoints on your course?

On-course timing points are ideal for timing and analyzing racer performance on specific sections of the course. If you're curious where racers gain or lose time, or when they crossed particular points, on-course timing points let you see exactly what's happening anywhere on the course.

GoChip makes it easy to add as many on-course timing points as you need - the chips carry their times back to the finish line, so you don't need any network connections at remote timing points.
