Brooks Adrenaline History: From the 1999 GTS 1 to the GTS 26
From the 1999 GTS 1 to the GTS 26: the miles that made the Brooks Adrenaline
The Brooks Adrenaline has spent more than a quarter-century showing up for important miles. Some ended with a first-place finish. Others ended with a first marathon, a personal best, a finish line someone was not sure they would reach, or simply another day of running that mattered.
History is not only made by the runner who breaks the tape. Your miles count, too.
When did the Brooks Adrenaline first come out?
The original Brooks Adrenaline GTS launched in 1999. Brooks says GTS originally stood for “Go-To Shoe.” The model was developed with feedback from specialty running retailers who wanted a supportive shoe that was more flexible and responsive than the Brooks Addiction.
By the Adrenaline GTS 4 in 2002, Brooks says the shoe had become its best-selling model. More than two decades later, the Adrenaline remains one of the most recognizable support-shoe families in running.
Brooks Adrenaline history: key moments
The Adrenaline GTS 1 arrives
Brooks enters the growing stability category with the Adrenaline GTS—then short for “Go-To Shoe”—built around retailer and runner feedback.
GTS 4 becomes a breakthrough
The Adrenaline GTS 4 introduces the Progressive Diagonal Rollbar, wins major running-industry awards, and becomes Brooks' best-selling shoe.
A future Olympian wins in Adrenaline trainers
At age 14, eighth-grader Emily Infeld wins Cleveland's city-championship 800 meters in 2:28. The high-school runners around her are in spikes; Infeld is in Brooks Adrenaline trainers. She later becomes an Olympian and World Championships medalist.
A first New York City Marathon
Runner Rafael Arvelo records his first NYC Marathon in the Adrenaline GTS 8, finishing in 4:00:12. It is the kind of story that defines this archive: not a product launch, but a runner's personal milestone.
Handcart Days Half Marathon victory
A runner blogging as Andy B. wins the Handcart Days Half Marathon in 1:26:17. His race-day log attributes the full 14.10 miles, including warm-up, to the Adrenaline 2010.
More wins in everyday trainers
Detailed race logs document an overall victory at the Weyco Turkey Trot in 23:57 for 3.8 miles in the Adrenaline 11, plus a 21:42 Santa Run victory in an Adrenaline 2011.
“Old faithful” for 50 miles
Before the JFK 50 Mile, one runner decides her newer shoes are not broken in enough and goes back to her “old faithful” Brooks Adrenaline ASR. She finishes the 50-mile event in 11:23:50.
A 2:38 marathon win in the Adrenaline 15
Riley Cook wins the Morgan Valley Marathon in 2:38:34. His race log records 26.22 miles in the Brooks Adrenaline 15—one of the clearest documented examples we found of an outright marathon win in the model.
The support concept changes
Brooks moves the Adrenaline away from the traditional medial-post / Progressive Diagonal Rollbar approach and into the GuideRails era. Instead of centering the design around correcting pronation, GuideRails are intended to provide support when motion moves beyond the runner's habitual path.
A first marathon and a sub-four goal
Chelsea Clinton runs her first New York City Marathon in 3:59:09 after setting a sub-four-hour goal. In a post-race Runner's World interview, she identifies the Adrenaline GTS 21 as her running shoe.
GTS 25 modernizes the platform
The Adrenaline GTS 25 continues the GuideRails era with DNA LOFT v3 cushioning and a 10 mm drop, keeping the franchise recognizable while evolving the feel underfoot.
The GTS 26 becomes the next chapter
The Brooks Adrenaline GTS 26 is scheduled to release November 1, 2026. It retains GuideRails™ structured support and DNA LOFT v3 while updating the cushioning, toe-off, engineered air-mesh upper and tongue.
Documented race wins in Brooks Adrenalines
We searched race reports, personal training logs, interviews, forums and running archives for examples where the evidence ties the shoe to the race itself, not simply to the runner's training block.
| Race / year | Runner | Result | Adrenaline evidence |
|---|---|---|---|
| Cleveland city-championship 800m, 2004 | Emily Infeld | 1st · 2:28 | Infeld told Runner's World she wore Adrenaline trainers while the other athletes wore spikes. |
| Handcart Days Half Marathon, 2010 | Andy B. | 1st · 1:26:17 | Race-day training log records 14.10 miles to Adrenaline 2010. |
| Weyco Turkey Trot, 2011 | DLTheo | 1st · 23:57 | Race-day log records the day's mileage to Brooks Adrenaline 11. |
| Santa Run – West Valley, 2011 | Andy B. | 1st · 21:42 | Race miles are specifically logged to Adrenaline 2011. |
| Morgan Valley Marathon, 2015 | Riley Cook | 1st · 2:38:34 | Race report records 26.22 miles to Brooks Adrenaline 15. |
What this does—and does not—mean: the modern Adrenaline is primarily an everyday structured-support trainer, not a carbon-plated racing shoe. These results simply show that runners have raced—and sometimes won—in the shoe they trusted for their regular miles.
Adrenaline history is bigger than winning
4:00:12 in New York
Rafael Arvelo's 2009 first-marathon story in the GTS 8 is a reminder that four hours and twelve seconds can hold more personal meaning than a podium.
50 miles in “old faithful”
At JFK 50 in 2014, familiarity won the shoe decision: the runner went back to an Adrenaline ASR she trusted and completed 50 miles.
A first marathon under four
Chelsea Clinton's 3:59:09 first NYC Marathon in the GTS 21 is exactly the kind of personal goal this history is meant to include.
The chapter nobody publishes
Most Adrenaline history has never appeared in a race report. It is the first uninterrupted mile, the return after time away, the weekly group run, the walking goal, and the shoe that simply kept getting chosen.
Be Part of Adrenaline History
History isn't only made by the person who breaks the tape. It's your first mile. Your first 5K. Your PR. Your first marathon. The race you almost didn't start. The finish you weren't sure you'd reach.
For runners since 1999, the Brooks Adrenaline has been there for those miles. Now add yours.
When you share an Adrenaline story with Confluence Running, tell us the model or year if you know it, the race or goal, what happened, and why that mile mattered. Photos, old bibs and well-worn shoes make the history even better.
What does “GTS” mean in Brooks Adrenaline?
When the Adrenaline launched in 1999, Brooks used GTS to mean “Go-To Shoe.” Today Brooks uses GTS for its GuideRails Technology System support shoes. That makes the acronym itself a compact history of how the Adrenaline evolved: from the dependable “go-to” stability trainer to a modern support platform built around GuideRails.

How we researched this history
Confluence Running separates manufacturer-confirmed product history from race-specific runner evidence. We count a race as an Adrenaline race only when a first-person report, race-day shoe log or direct athlete interview ties the shoe to that specific event. We exclude examples where the runner merely trained in Adrenalines but raced in another shoe. Product specifications for current models are checked against Brooks technical material and our own inventory records. This page will remain an editorial history, not a claim that every runner should race in the same shoe.
