On Sunday, Oct. 4, a few hundred Missoulians will gather at the Meadowlark Pavilion in Fort Missoula Regional Park, most of them wearing something purple. Pre-event festivities begin at 10 a.m., the Opening and Promise Garden ceremonies follow at 11 a.m., and then the crowd will set off on the 2026 Walk to End Alzheimer's — a fundraiser that has become, by the Alzheimer's Association's own accounting, the largest event of its kind in the world for Alzheimer's care, support, and research.
It is a familiar template: a charity walk in a public park, free to enter, with registration encouraged and donations the real point. But the ritual at the center of it — the Promise Garden — is doing something more specific than a 5K. It is a public accounting of who in a community has been touched by a disease that has no survivors to celebrate yet.
The walk's origins are modest. What began as a series of small, local "Memory Walks" organized by volunteers grew into a national event. The growth since then has been steep: today the Association describes the Walk to End Alzheimer's as held annually in more than 600 communities nationwide, and its Montana chapter promotes it as the organization's signature fall fundraising push.
The Missoula edition has its own local history, and it has not always gone smoothly. In September 2019, an early-season snowstorm forced organizers to move the walk indoors at the last minute — relocating it to Southgate Mall, where festivities began near the JCPenney and the opening ceremonies and walk followed. That year the Montana chapter's executive director, Lynn Mullowney Cabrera, framed the event in terms that still describe its purpose: "This a very meaningful, very moving opportunity for us to slow down, and pause to remember, to honor those living with disease, those we lost to this disease." The event was free then too, with donations "highly encouraged." In other years the walk has stepped off from the same Meadowlark Pavilion area at Fort Missoula Regional Park — the date has shifted year to year, but the venue and the ceremony have stayed constant.
That venue is itself worth a moment. Fort Missoula Regional Park is a 156-acre city-county park in the Target Range neighborhood, next to Community Medical Center, with its main entrance off the roundabout at South Avenue West and Guardsman Lane. It is a young park by Montana standards: Phase 1 was completed in 2017 with money from a 2014 county parks and trails bond, and Phase 2 followed in 2018. Its amenities are mostly athletic — nine multi-sport grass fields, 22 pickleball courts, seven softball diamonds, eight tennis courts, three playgrounds — plus event pavilions and picnic shelters and a network of walking trails. The Meadowlark Pavilion, where the walk gathers, sits within that complex. The park's name carries the older history of the site: this is the ground of the original Fort Missoula, and the surrounding neighborhood still carries military-era street names like Guardsman Lane.
What happens under the pavilion is the part that distinguishes a Walk to End Alzheimer's from an ordinary charity stroll. On arrival, participants pick up a Promise Garden flower and personalize it to their own connection to the disease. The colors are not decorative. Orange means you support the cause and the Association's vision of a world without Alzheimer's and all other dementia. Yellow means you are supporting or caring for someone living with the disease. Blue means you are living with Alzheimer's or another dementia yourself. Purple means you have lost someone to it. And white — held by a single person — represents the first survivor of Alzheimer's, a person who does not yet exist.
During the ceremony, the colors are introduced one at a time, and participants holding that color raise their flowers. It is, by the accounts of people who have attended walks around the country, the emotional center of the day: a field of orange and yellow and blue and purple lifted into the air, with one white flower standing in for a future that hasn't arrived. After the ceremony, walkers often place their flowers in the Promise Garden before leaving. Then the countdown, and the walk itself.
The stakes behind the ceremony are not abstract in Montana. The Association's Montana chapter runs support, advocacy, and research-funding work across a state that is large, rural, and sparsely served — the kind of place where a local walk and a local chapter phone line can matter disproportionately. The chapter's messaging this fall leans on the arrival of new treatments: "With new treatments emerging in the fight against Alzheimer's, now is the time for hope. Now is the time for action."
For anyone who wants to take part, the mechanics are simple. The walk is free, though registration is required and fundraising is the point; walkers can register as individuals or as teams through the Alzheimer's Association's walk site, and the Montana chapter can be reached by email at [email protected] or by phone at (406) 303-4426. The 2026 Missoula walk is set for Sunday, Oct. 4, with pre-event festivities starting at 10 a.m. at the Meadowlark Pavilion at Fort Missoula Regional Park and the Opening and Promise Garden ceremonies at 11 a.m., followed by the walk. Proceeds go directly to the Alzheimer's Association for care, support, and research.
The event's familiarity is, in a sense, the point. A community walk in a public park is a low bar to entry — no ticket, no athletic feat required, strollers and leashed pets generally welcome at these events, and seating available for those who would rather watch than walk. What the Promise Garden asks of the people who show up is not endurance but honesty: to name, in front of neighbors, why they came. For one morning in October, under a pavilion on the old fort grounds, that naming is the whole event — and the walk that follows is just the part where everyone moves together.
