Your Race. Our Clock. Results You Can Count On.

Race day should be exciting—not stressful.

RF Timing provides professional race timing, scoring, and finish-line services designed to make events run smoothly from the first starting horn to the final finisher. Based in Ann Arbor, Michigan, our team combines proven timing technology with years of hands-on event experience to deliver fast, accurate results and a race-day experience that looks as professional as it performs.

From a neighborhood 5K to a marathon, triathlon, relay, trail race, or large multi-distance event, if it has a start line and a finish line, we're ready to time it.

Great race timing isn't simply recording when someone crosses a line. It's creating a seamless connection between registration, race day, the finish line, results, awards, and the participant experience.

RF Timing can provide:

• Professional chip timing & scoring – Accurate, reliable timing backed by industry-leading race timing software.
• Live online results – Participants don't have to wait around for results to be posted. Results can be published online in real time.
• Live participant tracking – Give spectators, friends, and family the ability to follow the action as it happens.
• Text message results – Finishers can receive their results right on their phones.
• Finish-line video – Connect individual race results with finish-line video for a memorable participant experience.
• Online registration hosting – We can help take your event from registration all the way through race-day results.
• Custom & generic race bibs – Keep things simple or give your event a professional branded look with custom-designed bibs.
• Finish-line clocks – Large, easy-to-read two-sided clocks give participants and spectators an unmistakable race-day focal point.
• Inflatable finish arches – Create a finish line that looks as exciting as crossing it feels.
• Results & awards support – Fast, organized scoring helps keep your awards ceremony moving and gets everyone celebrating sooner.

Timing equipment matters, but the people operating it matter just as much.

Our goal is to make timing one of the easiest parts of your event. We work with race directors before race day to understand the event format, participant data, starts, distances, categories, and scoring needs. On race day, our team handles the technology and results so your staff can concentrate on everything else that makes your event special.

And when the first runners start flying across the finish line, we're already working behind the scenes to turn those timing reads into the results your participants are waiting to see.

Bring it on.

RF Timing works with 5Ks, 10Ks, half marathons, marathons, trail races, triathlons, relays, endurance events, and other competitions where accurate finish times matter.

Whether you're organizing a first-year charity 5K or an established event with thousands of participants, we'll help build a timing solution around your race instead of forcing your race into a one-size-fits-all package.

A great finish line has energy. There's a clock ticking, an arch overhead, spectators cheering, participants checking their results, and friends following along from home.

That's the experience RF Timing helps create.

Accurate timing. Fast results. Professional equipment. Experienced people.

You put on the race. We'll make every second count.
