Why We Wanted to Do This – The Story Behind the Record
The Ride That Changed Everything
It started with a question no one expected from two kids.
“Dad,” Aidan asked, helmet dangling from his hand, “do you think we could ride to the beach?”
The beach was seventy-seven miles away. Aidan was seven. Ethan was eight. Two tiny riders pedaling through New Jersey, helmets and sunglasses on, nothing fancy—just grit and determination.
Most people laughed. Most teams turned us down.
“You’re too young,” they said. “Too far.”
And Guinness World Records? They said no too. Kids aren’t allowed to do endurance events.
But these two didn’t quit. They made their own way. They trained when no kids’ cycling teams existed for endurance. They rode with adults because there were no kids who wanted to ride a hundred miles. And slowly, they found a tribe—the TNT team. Suddenly, they weren’t the kids who got turned down. They were teammates. They rode the Spellbound Century, Team Foster, Giro Del Vino. Every mile stretched their limits. Every finish line whispered, What’s next?

Why We Ride
We ride for Grandpa Dan.
He was a quiet man who never wanted anything fancy to remember him by. He just ran—mile after mile—half marathons, pushing his body past the brink, until he couldn’t run anymore. Parkinson’s took everything from him. His strength. His freedom. His voice.
But his mindset didn’t skip a generation. His determination to keep going is still strong in us. Every record we chase is for him. Every lap, every mile, every finish line is a way to say: We remember. We carry the torch. We keep moving because he taught us to never stop.

The Climb Begins
October came. 483 laps on a velodrome. A solo record.
November brought 6 hours and 47 minutes on a virtual trainer.
And then December.
December was supposed to be a break. A vacation in Hilton Head, South Carolina. Bikes would normally be put in the garage for the winter up north, snow piling high. But not here. Not in South Carolina.
Larry from WUCA lives in Hilton Head. He’s set more records than most people can imagine. He smiled and said,
“You know, there’s a course I’ve ridden a hundred times. You boys could make your own record here.”
Ethan looked at Aidan. Aidan grinned back.
“Six hours?” Aidan asked.
“Six hours,” Larry said. “A hundred miles. Two-person relay.”
And just like that, an ordinary trip became extraordinary.

The Day of the Attempt
The morning of the attempt, the sun was soft and golden. Dolphin Head Road stretched out like a promise—a perfect 1.3-mile loop.
“You ready?” Aidan asked, tightening his helmet strap.
“Born ready,” Ethan grinned.
They rode. Lap after lap. Larry cheering every turn. Mom handing out peanut butter pretzels, Annie’s chocolate chip cookies, and NUUN electrolytes like medals. Dad tracking every mile and making sure we were all safe on the road.
The first few hours were pure joy—laughing, trading turns, feeling unstoppable. And here’s the thing: together, they were faster. Solo, they average 16 mph. But as a team? They held around 18.5 mph for six hours straight. That’s the magic of brotherhood—pushing each other beyond what either could do alone.
But then came the hardest part. The wind. It kicked up in the afternoon, hard and stubborn, pushing cold from the north. Temperatures started to dip. Every lap felt heavier.
“This is brutal,” Aidan laughed as he rode into the wind.
“Just a stretch,” Ethan said. “We’ve got this.”
And they did. They pushed past the wind, past the fatigue, past the doubt. After 100 miles, they still had to keep going until the clock hit six hours. Every minute felt longer than the last and they passed 88 laps but kept going. But when the timer finally stopped, they were still smiling. Two brothers. One mission. A record set on vacation. They broke together the 6 hour barrier for 100 miles.
Even on vacation, when most kids would be building sandcastles, they chose the saddle. Because there’s never a perfect time to chase a dream. You show up. You ride. You finish.

Why It Matters
This wasn’t just about cycling. It was about proving that big dreams don’t wait for permission. It was about family—the kind that cheers every lap, packs snacks, and stands in the cold because they believe in you. It was about brotherly love from Philadelphia, where siblings learn to work together as a team, but when it matters most, the bond is closer than we think.
Because sometimes, the greatest victories aren’t just on the road—they’re in the moments when two brothers look at each other and say, We’ve got this.
Thank you to TNT for believing in us, to Mom and Dad for every mile of support, to Larry for cheering us on, and to everyone who helped us get to the finish line.
Come join us and set a record with us in 2026.
