It always seemed a stretch to see the RaceRanger draft-detecting technology, which has become a mainstay at IRONMAN Pro Series, T100 and World Triathlon professional races, become a viable option at age-group races, but we could see that happen over the next few years. Originally conceived by former pro triathletes James Elvery and Dylan McNiece in 2014, RaceRanger got some financial backing from World Triathlon in 2017, and has been working closely with Jimmy Riccitello, IRONMANās Rules and Projects Coordinator since 2018.
Scaling up from a pro race with roughly 100 athletes is one thing, but being able to offer the service to hundreds, or even thousands, of competitors offers some daunting challenges for the New Zealand-based company. We caught up with Elvery to get some insights into where things stand as RaceRanger looks to expand its offerings to age-group racing in the future.
Slowtwitch.com: Letās start with the 2026 RaceRanger forecast ā where are things at?
James Elvery: 2024 was a big year where we grew to 37 pro races. The goal for 2025 was not to try and grow the number of pro races further, but to stay home more and work on the next version of the hardware and the whole system, with a view to making it really scalable.
So you personally werenāt at every race in 2025?
In 2024, I went to 25 races. But in 2025, I went to only eight. We had two people in Europe and one backup in North America. I came in and did some of the championship races where there was more media and I was more likely to get meetings with the decision makers for the following season. Weāve got the system pretty easy-to-operate and a growing team to run it now. This year, thereāll be two fairly full-time people in Europe and another two in North America.
How many races are you looking at for 2026?
We have more and more events coming to us. So far we have 65 events contracted for the year. A lot of that growth is from IRONMAN, where thereās an expansion beyond the pro series. I think there are around 60 pro races where slots are given away for 70.3 Worlds and Kona, and they, of course, want those to all be operated as fairly as possible. Also, with the 20-meter draft zone change, having Race Ranger at races where it hasnāt been before helps referees and athletes understand what 20 meters actually is.

The original vision was always that age group racing would be the make or break for RaceRanger. Is that still the goal?
Very much so. All of last year was spent refining the product and the whole system to make it as scalable as possible. Weāre now making a new version of the rear unit and a lot of peripheral infrastructure that people wonāt always see ā the back-end systems that make it possible to do really big numbers. Weāve done lots of pro races, probably around 100 pro events now over the last three or four years, some with 100 to 120 athletes. Then we did one in February last year with 285 age groupers in Wanaka, and that confirmed a few pinch points weād identified. Weāve now hit go on production of 900 new sets, which we should have in-hand around mid-April. With those, plus the roughly 300 we already have, weāll be in a position to do a larger age group event ā ideally in New Zealand over the summer months, so we donāt have to ship everything overseas for the trial. Weāre lining up good candidate races toward the end of this year and the start of next.
Can you walk us through the main pinch points youāve identified for scaling to age group racing?
Sure. The first one is fitting the units. We were basically telling athletes to arrive at bike racking time ā usually the day before the race ā and it would take roughly five minutes to fit the units per bike. That works fine with pro numbers, but itās not going to work for a thousand or three thousand athletes. Youād need a team of 20 people and there could potentially be huge queues. So, weāve moved to distributing devices at registration, giving people enough time to fit them before they rack their bikes. For a 70.3, we found that giving them out at the briefing meant athletes were basically coming straight to bike racking with the pack ā they didnāt have time to actually fit it. So, two days before, when registration opens, works much better.
The second pinch point is tracking which unit belongs to which athlete. Weāve been putting race number stickers on the devices ā which meant buying a professional sticker printer, cutting them all, and then spending two or three hours in the hotel before each race matching serial numbers to the current start list. Thatās a big time suck, and it wonāt scale to 3,000 athletes. So, going forward, there wonāt be number stickers on the devices. Instead, thereāll be a QR code on each unit, and weāll scan it together with the athleteās wristband QR code at registration to link them in our system.
The third is controlling the devices at the race. Weāve been using an iPad over Bluetooth, which works fine for maybe 200 athletes in an area, but beyond that the range breaks down. Now that weāve added SIM cards to all the units, weāre moving to an online platform ā sending commands through the internet to each device. We donāt even have to be at the race to do that. It also means we can push firmware updates remotely, and to thousands of devices in parallel.
Then thereās recovering devices after the race. If someone DNFs, weād have to scramble to find them or their bike ā sometimes athletes just go back to the hotel. With live tracking, weāll be able to locate devices much more easily. The tracking frequency will drop after the race to preserve battery, but weāll always know roughly where everything is.
And finally, washing them. Weāve been hand-washing with a towel and soapy water. That wonāt work for thousands of units. We want to run them through a commercial machine, like a commercial dishwasher, 50 at a time. But, to survive that, they need a higher level of waterproofing ā so weāre moving to a design with screws and a proper seal.

The vision was originally to get it down to one unit instead of two. Where did that land?
We worked really hard on that for the first four or five months of last year. We got it working about 90 percent of the time, but for that other 10 percent ā when the course might pass through areas with weak cell signal ā it was really hard to get it as reliable as the two-device setup. So, we settled on a compromise, and this is where we need the events to buy-into what RaceRanger can add to the sport, as it requires the splitting of age group fields into two categories. For a typical age group field, thereās a competitive portion, with athletes that are serious about triathlon as their sport. Then there are people who are perhaps newer to the sport and are there more for a personal challenge, rather than the competitive motivations. A lot of this group might not even know what drafting is.
So, the idea is to offer two categories: a competitive category with two devices each, for people who want to race fairly, be actively policed and potentially qualify for worlds, and a participation category who are given just a rear unit and the focus can be more on safety, having fun and their connection with their supporters. For the general participation group, we donāt want a sea of flashing red lights going, so their lights would only activate if they went in front of a competitive athlete.
Weāre not sure exactly what the split of uptake between the two categories would look like ā estimates Iāve heard range from 10 to 50 percent taking the competitive option ā but thereād at least be a group that only needs the rear unit, which saves a lot of time and gear to haul between events. And the ones who are competitive probably want exactly what the pros have, and value the fairness benefits and clearer roads.
I strongly believe the split category model would be a really positive thing for triathlon. The event can then better cater to both groups, address the problem of competitive athletes not really getting a fair competition at the moment, and providing something for the āone and donesā to aspire to as a next step, and keep them in the sport.
Whatās in it for the participation category athlete who still has to put a device on their bike and pay for it?
Thatās where the live tracking system comes in. Everyone in the race who has a unit is constantly being tracked, which gives the event visibility of where everyone is at all times, but will also massively improve the tracker app experience for spectators. For participation athletes, that connection with their supporters is often a really big part of their race day. Iām often surprised talking to first-time finishers about how not just their family, but their whole office was following them on the tracker. Thatās often how we get new people into the sport ā following someone through their journey and getting inspired to do it themselves.
Weāve also got a vision for a post-race replay feature, where youād get a course profile showing every interaction you had with other athletes ā where you overtook someone, how fast you both were going, whether you were earned any illegal time through that pass etc. You could filter it by age group, compare your stats with others. Your results, available on your customer profile page on IRONMAN.com become a lot more than just a swim, bike, and run time, and hopefully it makes doing the race more engaging and motivates more people to come back and do another one.
RaceRanger Age Group Test Offers Insights on Future Potential and a Glimpse of Athlete Drafting Data
Whatās your read on where IRONMAN stands with all of this?
Iād say theyāre cautiously supportive. They probably want to iron out the details and see it in practice. When you first think of RaceRanger for age groups, the mind jumps to a sea of crazy flashing red lights everywhere and chaos ā so itās really a matter of working through and understanding everything weāve thought through and then for us to show it in action at some races as soon as we can. We plan to do a pilot event ā not a 3,500-person race, more like around 1,000 people ā to at least demonstrate that a good chunk of people value a fair race and that the live tracking is a real benefit for everyone else. But, we havenāt signed a deal for 50 age group races in 2027 or anything like that yet! Itās still a work in progress. A realistic timeline for age groups is that we could see some larger demonstration events at the end of 2026 / early 2027, and more widespread adoption in 2028.
Talk to us about the investment side ā building all of this out must have been a significant undertaking.
We started working on this new design and all the scalability improvements early last year, and itās finally in production now. Thankfully our existing investors have came along for the ride ā we did a capital raise, and thatās allowed us to go ahead with the production run and should also keep us going for at least the next two to three years, which is nice. Weāll be doing a bit of a public push from early April to see if we can find a few more investors to add on top of that. But, yeah having that funding in the bank does take a lot of stress out of things. But thereās then still a lot of pressure to get it right. If something goes wrong with the build and 900 units all donāt work, weād be in big trouble!
What about data ownership and releasing race data to the public? Thereās been a lot of interest in that ā especially after the Roth situation last year.
Generally the events own the data. Anything we gather at their event is theirs to do with as they choose. We can configure what gets reported ā T100 events, for instance, ask us to exclude certain course segments like a chicane or a technical feature. With IRONMAN we just exclude the transition area. What they do with that data is up to them.
In terms of releasing it publicly, our main focus has been on getting data live to referees as itās happening, rather than publishing post-race reports. Weāve been working on a referee app ā a communication tool and penalty-logging system that works for any triathlon, from small races to IRONMAN distance. Its ben trialled and tested at eight events now, including a few big ones like WTCS Hamburg and the Grand Final in Wollongong. When RaceRanger is also on the bikes, the drafting data will soon feed directly into that app for the motorbike referees.
As for the privacy side, there are real concerns. If we publish data that makes someone look bad and they say they didnāt consent to that being released, thatās a problem weād like to avoid. We envisage a set of new clauses in race agreements covering location tracking and data use before we could go down that road.
What about the 20-meter draft zone change? What was Race Rangerās role in those tests, and were you surprised IRONMAN moved so quickly?
For our part in the test, we set up a modified version of the normal race program where the blue buffer zone was moved to sit right on top of each distance threshold and shortened to one meter, and we told the athletes to try and hold that blue light as closely as they could. We recorded the following distances ten times per second for every run ā around 12,000 lines of data per athlete per round. That let us pinpoint exactly when an athlete was holding the zone we asked them to, timestamp by timestamp, and hand that clean distance data to Marc (Graveline), who then applied the power profiles and CdA analysis. It was just something thatās never been done before. I flew from New Zealand to Arizona twice to be part of it ā it wasnāt something thrown together.
As for the decision to move as quickly as they did ā I thought theyād do a couple of trial races and then review it. But they made a bold call, and itās good to see. It doesnāt change a lot for us operationally. Weāre generally reprogramming the devices before most races anyway, so switching between the 12-meter and 20-meter version is just a setting. And if we donāt need to maintain two versions going forward, well, my engineers are probably pretty happy about that ā though weāll still keep the 12-meter version ready for when we get to age group racing.
