What We Offer

Chip Timing
Fully Automatic Timing (FAT)

We offer dual frequency (triathlons and duathlons) and UHF (running and cycling) chip timing.

We use a high-speed Lynx camera at all cycling races, as well as several Identilynx backup cameras, to accompany the chip timing system.

Race Management

We are able to help set up your registration page, help build a race course, and manage your event on race day.
