TLDR; Chip timing uses RFID technology to track when each participant crosses timing points throughout your course. It ensures accurate start and finish times, improves the participant experience, and streamlines results. This post breaks down how it works, why it matters, and what to expect on race day.

When you’re organizing a race, there are a lot of moving parts — and timing is one of the most important. Chip timing has become the standard for endurance events because it’s accurate, efficient, and scalable. But if you’re new to producing races, you might be wondering how it actually works and whether it’s worth the investment.

In this post, we’ll break down how chip timing works, why it matters, and how it can elevate your event for participants and organizers alike.

What is chip timing?

Chip timing is a method of tracking a participant’s start, finish, and (in some cases) split times using a small electronic chip, most commonly using radio-frequency identification (RFID) technology. There are many other timing technologies currently being used in the endurance community. Check out our blog What timing technology is right for your race? to learn more about the various technologies currently being deployed.

Each athlete wears a chip — usually embedded in a race bib, attached to a shoe, or strapped to an ankle. These chips communicate with antennas (often called timing mats or timing antenna) placed at key points on the course. When a chip passes over or near a reader, the system logs the exact time — capturing each participant’s performance down to the millisecond.

Chip timing has become the standard for running races, triathlons, cycling events, and multi-sport formats of all sizes — from smaller community 5Ks to events with 10’s of thousands of participants.

How chip timing works

Here’s a high-level overview of how the process works:

  1. Participants are assigned timing chips – These may be disposable or reusable and are tied to each athlete’s bib number in the timing software.

  2. Chips are worn during the race – Usually attached bibs, shoes, or ankles.

  3. Timing antennas (mats) are placed at key locations – At the start, finish, and any on-course split points.

  4. Chips are detected as they cross mats – Each detection records a timestamp to that unique chip.

  5. The data is processed in real-time – Timing software (like RM Timing Systems, RaceDay Scoring, Copernico, etc.) interprets the data and sends it to an online results page, live leaderboards, or announcer screens.

  6. Final results are generated – Once verified, awards reports are generated or finalized.

Why chip timing matters

Accurate timing does more than determine who wins a race — it shapes how your event is perceived.

✅ Gun Time vs. Chip Time

With chip timing, every participant’s start time is personalized. That means runners in the back of the pack aren’t penalized for crossing the start line 30 seconds after the gun. This fairness is especially important in larger events and events with wave starts or corrals.

✅ Real-Time Results & Tracking

Live leaderboards, split tracking, and instant mobile updates all enhance the athlete and spectator experience. With proper timing infrastructure, participants and fans don’t have to wait for results — they’re posted as the event unfolds.

✅ Professionalism & Efficiency

Chip timing adds credibility and polish to your event. It reduces volunteer burden, speeds up awards, and provides clear documentation of every participant’s result.

Why work with a professional timer

While chip timing technology is powerful, it only works well when it’s deployed by an experienced team. From pre-race planning to race-day execution and real-time result management, a professional timing partner ensures things run smoothly — and gives you one less thing to worry about.

At Negative Split Productions, we bring more than a decade of experience in race production and technology. We use RM Timing Systems, TridentRFID hardware, and Atlas Live software to deliver real-time, reliable results for races of all sizes.

Even with top-tier equipment, there’s always a chance of a missed read — due to chip placement, athlete movement, or environmental factors. That’s why we always deploy a camera backup system at the finish line (and sometimes at splits). Every finisher is visually recorded and synced with chip data, so we can verify results and make corrections in real-time if needed. No guesswork, no stress.

It depends on your race format. For a standard 5K or single-loop course, start/finish mats are often sufficient. But if you’re organizing a longer race, multi-loop course, relay, or triathlon, adding split points can provide valuable data and peace of mind for both athletes and spectators. We can help you determine the best setup based on your course and timing goals.

We use disposable chips for most running events, typically installed on the back of the race bib. For triathlons and multi-sport events, we use reusable ankle-strap chips that are waterproof and designed for transitions. We’ll recommend the best option based on your event type, budget, and timeline.

Not at all. In fact, small events benefit from chip timing because it removes the margin for error and speeds up the process for both participants and organizers. You’ll get clean, professional results even if you only have 100 runners — and your volunteers won’t be stuck writing down bibs at the finish line. We have a very cost-effective solution using Bluetooth technology.

Not necessarily. We offer timing packages to match a range of event sizes and budgets — and many of our clients find the cost is well worth the time savings, data accuracy, and improved athlete experience.

We’re always happy to chat. Whether you’re timing your first event or looking to upgrade your current setup, we can walk you through the options and recommend a plan that fits your race.
