An interview with the Race Master about Manhattan's first GPS-tracked urban puzzle hunt
After 34 years of organizing puzzle races, the 2025 Human Race marked a significant evolution - the first walking-based urban puzzle hunt through Manhattan, powered by custom GPS technology and real-time web applications. With teams navigating 11 clues across the city while battling both mental challenges and physical exhaustion, the race provided invaluable lessons about game design, technology integration, and human nature.
From Cars to Feet: The Manhattan Decision
The transition to walking wasn't philosophical - it was geographical. "Clearly with the race being in Manhattan, the idea of a driving race was a non-starter," explains the Race Master. While he had run almost exclusively driving races in the past, he did organize a Manhattan walking race in 2001 and participated in one designed by his ex-wife in 2005, providing crucial context for urban puzzle design.
The weather forecast nearly derailed participation entirely. "The weather forecast was abysmal early in the week - I could understand why teams were waiting until the weather improved." Thunderstorms and hail were predicted, driving a surge of last-minute signups as the forecast improved. Miraculously, "I did not experience a single drop of rain the entire race."
Promotion proved challenging without the anticipated charity partnership. "I was expecting a more significant push from the charity that the race was organized to benefit," but between organizational issues and last-minute liaison problems, promotion largely fell to individual efforts through Time Out New York, Craigslist, and even the local MENSA publication. The result? Eleven teams registered (with three more trying after the deadline) and nine showed to the starting line - "and that's still great."
Technology Evolution: Embracing the Internet Age
One of the most significant philosophical shifts involved accepting rather than fighting technological change. In previous decades, teams could reasonably be expected to rely on their own knowledge or physical reference materials. By 2025, attempting to ban internet use would be futile.
"I either had to request that racers do not use the internet, make efforts to make the race incompatible with using the internet or just embrace that that is the world we live in now and go with it, and so I went with it," the Race Master explains. This meant trivia wouldn't be the stumper it had been in the past, requiring more creative puzzle design focused on problems that couldn't be easily Googled.
The landmark verification questions (like pay station zone numbers and fire hydrant digits) represented a throwback to earlier races where teams needed to verify their physical presence. However, with GPS location validation, these became somewhat redundant - though they provided a backup verification method.
The Virtual Revolution: From Envelopes to Algorithms
The transition from physical envelopes to digital clues opened new possibilities. Previous races required teams to carry every clue in physical envelopes, with landmark numbers serving as keys to open the next envelope. The 2025 race's virtual system, developed with AI assistance, eliminated the need to coordinate with businesses while enabling dynamic puzzle types.
However, logistics played a major role in the decision. "I was expecting a whirlwind of team signups, and at 20 teams that would have been 300 envelopes I would have had to prepare, and that was clearly too much." In the traditional system the clue envelopes the teams carried included 20-30% extra "red herring" envelopes with disqualification warnings, creating entertaining psychological pressure while preventing random envelope opening.
GPS Challenges and Solutions
Manhattan's concrete canyons presented significant GPS reliability concerns. "I was very concerned about reliable GPS in Manhattan's concrete canyons. Ironically I was testing an AR version of the clue locations (literally popping up virtual signs when you got in range of the clue) and that tracking was even unreliable here in the suburbs."
The AR concept was abandoned due to accuracy requirements - unlike GPS tracking with a 500-foot tolerance window, AR signs needed precise placement. "Imagine if I expected a clue to be on the street and it ended up inside a building. Or worse, yet, in the middle of the street? Fun for me to contemplate, but much too dangerous and unreliable."
Backup systems proved essential, including location validation backdoors and direct communication channels for technical assistance.
The Accidental Discovery: Digital Scouting
The race's most significant innovation emerged accidentally. Teams discovered they could validate puzzle solutions remotely by testing whether the location portal would accept their answer, receiving either "You're not there yet" (correct answer, wrong location) or "I don't know that location" (incorrect answer).
"I never knew they were using the 'you're not there yet' to validate their solutions until they told me at the finish line," admits the Race Master. Teams discovered this organically without sharing the information, and it saved them "tons of walking in the wrong direction."
This transformed the race from wandering-based exploration to strategic puzzle-solving: teams could now solve clues intellectually first, verify their answers remotely, then walk directly to the correct location with confidence.
The discovery highlighted a crucial difference between car and foot races. "In races of the past they raced in cars. This was on foot. Walking half a mile in the wrong direction may be entertaining for me, but not for the feet that are doing the walking!"
Real-Time Race Management
Race day brought the full complexity of modern event management. "I was juggling those things and watching in amusement, as you say, 'my creation came to life,'" describes the Race Master, referring to balancing technical support, GPS monitoring, and race observation.
The most dramatic moment came when the leading team discovered a critical error - a vestige from late-stage course design where teams were instructed to open an envelope they didn't have. "I sat down on a bench outside of the Oculus and did some mid-race SQL updates to correct the oversight." The fix was implemented before other teams reached the problematic location.
This exemplifies what he calls "the price of being in the lead" - leading teams discover problems for everyone behind them. After three decades of race management, such challenges feel routine: "Different than other mid-race fixes I've had to implement before, but relatively expected."
Team Dynamics and Completion Rates
Of nine starting teams, five finished - a respectable completion rate for a walking-based urban puzzle hunt. The dropout analysis revealed important insights:
•One team withdrew strategically (at clue 4 of 11 when others had already finished)
•Three teams dropped due to physical exhaustion
Team size dynamics proved crucial. While the Race Master encouraged larger teams, he accepted that "if you're good, you're good." However, two-person teams faced unique challenges: "When you're disheartened it is a lot easier to convince just one other person to quit than two." Interestingly, larger teams (5+ people) also struggled, as "two or three out of five can quite easily bring down the group."
Clue Design Philosophy
Balancing puzzle difficulty remains "more art than science," especially with internet access solving traditional trivia. The Race Master uses a "feel" for difficulty and distributes challenges throughout the course, with many clues being "portable" - abstract puzzles that can work at any location.
However, Manhattan's character must be woven into the experience without over-relying on local knowledge. "It's a little... cloying to gravitate to the true landmarks," he explains, preferring locations that are distinctly Manhattan but not so obscure that out-of-town teams have no chance.
Testing reveals consistent surprises: clues expected to be easy become difficult, while anticipated challenges prove straightforward. A particular clue worked as intended (essentially "another abstract clue but with more steps"), while the another puzzle meant as a simple "time suck" became unexpectedly challenging. Teams struggled because they remained in "abstract puzzle" mindset when it was actually a literal "spell it out" clue requiring them to simply "just do it".
The Virtual Completion Solution
Recognizing that some teams might want closure, a virtual completion mode was developed specifically for teams that ran out of time but maintained motivation. "I do hope that the teams that didn't finish go back and try the virtual completion. Not only to see what they missed for themselves but to have the opportunity to appreciate the race in its entirety even if they couldn't on the day of."
The system serves multiple purposes: providing closure, maintaining engagement for future events, and offering potential insight into whether teams that dropped early might have recovered with different circumstances.
Lessons from 34 Years: The First Clue
The evolution of team creativity spans the entire 34-year history. The very first clue of the very first race set the pattern that continues today. Placed at the midpoint of a mile-long drawbridge to Seaside Heights, the clue read: "As the bridge does rise, here the men will sit, to get here, though, you'll need your wit."
The expectation was teams would park at either end, and walk half a mile to the center. "Imagine my surprise when the very first team simply drove along the bridge like any other car and then stopped dead center on the bridge, jumped out of the car, grabbed the clue, jumped back in and carried on like any other day."
That moment established the fundamental principle: if it's not explicitly forbidden, teams will find the most efficient solution, regardless of whether it matches the designer's intent. "It was at that point I knew that the teams would do some crazy things to win this race (which has never had anything more than pride as the 'prize' for coming in first). And they haven't stopped surprising me yet."
Looking Forward: Future Race Evolution
Plans for the next race involve surveying participants about their preferences. Manhattan remains a strong possibility, though Philadelphia has been floated as an alternative. There's also consideration of returning to the race's origins at the Jersey Shore, though the logistics of travel accessibility remain a concern.
The driving vs. walking question continues to evolve. While the Race Master has "an itch to go back to the race's roots and make a driving race," many participants specifically chose this race because it was walking-based. In New York City, where many people don't own cars, this makes practical sense.
Key improvements for future races include:
•Implementing the scouting feature as an official mechanic
•Required phone number collection at registration for better team communication
•Enhanced real-time communication systems for sharing discoveries across all teams
•Better initial technology orientation to prevent confusion at the starting line
The Philosophy Behind the Puzzles
Despite a deceased friend's accusation that these races exist "to prove to everyone how much smarter than them the Race Master is," the actual motivation is the opposite. "I craft these races in the hopes that people can solve them, and have fun getting there. I probably could make a race with the intent 'to prove how much smarter than everyone else I am' (though I don't think that I am), but what good is a puzzle that no one can ever put together?"
This philosophy drives every design decision: creating challenges that stretch teams' abilities while remaining solvable, balancing physical and mental demands, and continuously adapting to new technologies and team strategies.
The Midnight Madness Legacy
The entire 34-year journey traces back to the 1980 movie Midnight Madness, which inspired the original vision of becoming like the film's Race Master, Leon. Ironically, the internet has made the movie's clues unusable, and the Race Master had intended to use the movie’s first clue as the first clue in Manhattan 2025 - "you can just Google the movie's script... and, when you get down to it, the clue just didn't make any sense, really."
This perfectly encapsulates the challenge of modern race design: staying ahead of infinite information access while creating experiences that reward intelligence, creativity, and teamwork rather than raw search capability.
