What is a masters athlete?
You can start running at your own level. An age category does not set your pace.

General information, not individual medical advice. For questions about symptoms or readiness to run, speak with a clinician who knows your health history.
What age is a masters athlete?
You do not need years of running behind you to start now. We built First Gear for adults beginning or returning to running, and that includes people whose first outing comes well into the masters age groups.
World Masters Athletics begins its age categories at 35. The brackets run in five-year groups: 35 to 39, 40 to 44, and onward. The age category itself is not a performance score. [1]
If you want to enter an event, check its rules. Age thresholds and entry requirements vary by sport and event. If you simply want to go out for a walk and a jog, you can leave the race decision for another day.
What does the term mean in a study?
When we share research on masters athletes, we look at how those people trained. In the muscle study discussed in our running science guide, the participants were high-level recreational athletes who trained several times a week. Recreational does not mean new to exercise. [2]
A review of masters endurance athletes also drew on people with established training histories. Its findings about changing training volume do not prescribe a starting routine for someone who has been inactive. [3]
Take inspiration, then choose your own first step
Ask who took part, what the researchers measured, and whether they followed people over time or compared different people at one point. That keeps a striking headline useful without turning someone else's training history into your assignment.
Studies of experienced athletes help us understand training and aging. They cannot promise you the same outcome or separate all the reasons those participants were able to keep training. Take the encouragement, then start from the activity that fits your life now.
We give you a concrete place to begin: a twenty-minute session on Apple Watch that starts with a walk. In standard coaching, your heart-rate readings guide spoken cues for jogs and walking breaks. You can keep walking or finish early. There is no pace to qualify for.
Your first First Gear session is free, with no subscription. Choose a familiar path, set aside the time, and start with the walking you can manage. You can decide about races later.
What if you are not a masters athlete at all?
You do not have to be one to run, and nobody is checking. A masters category is not a bar to clear. It is a label for people who compete.
First Gear is built for adults who want an easy routine. Each session opens with a walk, your heart rate decides when your coach cues a jog, and your coach calls a walk as you head toward the top of an easy range. There is no race to enter and no pace to hit.
Your first step can be a walk.
Start your own run/walk routine with First Gear on Apple Watch. Your first session targets twenty minutes and begins with walking. It is free, with no subscription. Download it on the App Store.
Common questions
What age do you become a masters athlete?
World Masters Athletics starts at 35, with five-year age groups. Other sports and research studies may use different thresholds. You can start your own running routine at a level that fits you, whether or not you plan to compete.
Do masters athletes have to be fast?
The age category does not set a speed, although individual events may have entry requirements. First Gear has no target pace to hit: our first session begins with walking, and you choose how to respond to the coach.
Do results from masters athletes apply to beginners?
They offer context, not a prediction of your results. Check the participants' training history and health, the study design, and what was measured. We use that same distinction when discussing research on the First Gear blog.
Can I use First Gear if I am starting later in life?
We designed First Gear for adults beginning or returning to running, including older adults. Sessions start with a walk and target twenty minutes. Age alone cannot establish whether running is appropriate for you. Ask a healthcare professional if you have a condition, take medication, or are unsure about starting.
