SCOTTSDALE, AZ – The Stack System today announced the Fall 2026 Seasonal Circuit, an eight-week global wedge competition designed to bring structure, purpose, and competition to golf practice. The Fall Seasonal Circuit begins October 3 and is open to Stack Radar users through TheStack App.
Each week, golfers complete a new scored wedge combine at home into a net or on the driving range. Players can repeat each combine as many times as they like to improve their score and climb the global leaderboard.
“Golfers practice differently when every shot counts,” said Dr. Sasho MacKenzie, co-founder of The Stack System. “Seasonal Circuit gives wedge practice the elements that are often missing; structure, pressure, feedback, and competition. Instead of simply hitting balls, you have a specific test and a score you are trying to beat.”
Eight Weeks of Competitive Wedge Practice
The Fall Seasonal Circuit runs for eight weeks, with a new wedge combine released each week. Each combine challenges golfers to control carry distance across a variety of targets, turning distance control into a measurable skill.
Players compete alongside Stackers around the world on a global leaderboard. Because each combine is repeatable, golfers can establish a benchmark, identify the distances that need work, and return to improve their score.
Only a player’s best six results from the eight-week season count toward their final score, allowing golfers to miss up to two weeks without compromising their season.
“The goal isn’t simply to see who is the best wedge player on day one,” said MacKenzie. “It’s to create an environment where golfers want to come back, practice deliberately, and see if they can perform better the next time.”
Giving Practice Something to Chase
Seasonal Circuit builds on Stack Wedge by adding an ongoing competitive layer to distance-control practice. Every shot contributes to a score, every score establishes a benchmark, and each week presents a new opportunity to improve.
Seasonal Circuit also includes a ballot-based prize system. Golfers earn prize-draw ballots based on their season ranking, while any player who completes at least one combine is eligible to win. The format rewards strong performance while giving golfers throughout the leaderboard a chance at the season prize.
What Golfers Need to Participate
Participating requires a Stack Radar, an iPhone or iPad running TheStack App, and a place to hit golf balls. Combines can be completed into a net or at a driving range, with Stack Radar recording each shot and sending the data directly to the app.
Fall Seasonal Circuit Begins October 3
Week 1 begins October 3, 2026. Golfers who do not yet own a Stack Radar can join after the season begins; because only six of eight weekly results count, players can miss the opening weeks and still complete a full qualifying season.
Seasonal Circuit extends the same principle behind The Stack System’s training and practice products: give golfers a clear objective, measure performance, and make improvement visible over time.
