Why do beginner runners get injured?
Start with room to walk, repeat, or stop. Your first session is yours to adjust.

General information, not individual medical advice. For questions about symptoms or readiness to run, speak with a clinician who knows your health history.
How common are injuries in new runners?
Running injuries per 1000 hours, novice against recreational
Your first session should leave room to walk, repeat, or stop. We built those choices into First Gear because you keep the final say, even when your coach gives a cue. Take pain seriously and get advice when you need it.
A meta-analysis estimated 17.8 running injuries per 1000 hours in novice runners, compared with 7.7 in recreational runners. Definitions and populations varied, so these figures do not predict whether you will get injured. [1]
The comparison does not identify a single cause or prove that any particular coaching method prevents injury. Our approach gives you practical choices during the session, while keeping assessment of pain with a clinician.
Does shin pain always mean shin splints?
No. Shin splints are one cause, but stress fractures, tendon problems, and other conditions can also cause lower-leg pain. AAOS emphasizes an examination to establish the cause. [4]
A review of shin splints in novice and recreational runners found limited-quality evidence about risk factors and treatments. Bring your symptoms and questions to a clinician who can assess your leg. [2]
Pause running that hurts, including during a coached session. If pain persists or returns, arrange an assessment and explain when it began, what brings it on, and any recent changes in activity. You do not need to finish a First Gear session before acting on pain.
Does the 10 percent rule prevent injury?
It is a common planning rule, not a validated personal limit. A randomized trial found no reduction in injuries with a 13-week program using the 10 percent rule compared with an eight-week program. [5]
That does not mean you should rush. One percentage cannot decide the right progression for everyone. In First Gear, you can stay at your stage when an advance is offered. The choice is part of our program; it does not certify that your tissues are ready for more running.
Give yourself room to change the plan
In a study of 110 people in a modified nine-week Couch-to-5K program, 27.3 percent completed it. Injury featured among the reasons given by dropouts who were interviewed. This does not establish a completion rate for all beginner runners. [3]
That study cannot show whether a calendar caused the injuries or whether a different plan would have prevented them. We give you room to adjust in First Gear: stay at your stage, keep walking, or end early. Pain is a reason to seek help, whatever your plan says.
Start with a session you can change
Choose a walk you can manage and leave room to finish early. When running is appropriate, short jogs with walks between them give you a way to try it without setting a distance goal for day one.
Your first session with First Gear targets twenty minutes and begins with walking. Standard coaching uses heart-rate readings to call jogs and walking breaks on Apple Watch. You hear the next cue and choose how to respond. You can keep walking, repeat your stage, or stop the session.
First Gear cannot assess tissue recovery, diagnose pain, or confirm that an injury has healed. Our stages organize practice; they are not tests of fitness or clinical readiness. Keep any recovery plan or exercise limits from your clinician in charge.
Your first session is free, with no subscription. If running is appropriate for you, try the walk-first session and get to know the coach at your own pace.
Give yourself a first session you can adjust.
Start with a walk and a twenty-minute target. First Gear puts run/walk coaching on Apple Watch, with the choice to keep walking or finish early. Try your first session free, with no subscription. Download it on the App Store.
Common questions
Why do my shins hurt when I run?
Shin pain has several possible causes, including shin splints and stress fractures. Neither this guide nor First Gear can diagnose yours. Pause running that hurts and get an assessment if pain persists, returns, or changes how you move.
How do I start running without getting injured?
No plan can guarantee that. Choose a manageable starting point, keep room to repeat or shorten sessions, and get advice about existing pain or a previous injury. First Gear includes those choices, but our heart-rate cues cannot assess whether your tissues are ready.
Is the 10 percent rule proven?
No universal injury-prevention effect has been established. The trial discussed here found no reduction in injuries with a program based on the rule. We treat First Gear's stage criteria as program rules too; an offer to advance is not clearance to increase running.
When should I get help with running pain?
Arrange an assessment for pain that persists, worsens, or changes how you walk. Seek prompt care for severe pain, swelling, or difficulty bearing weight. Stop the coached session when you need to; a watch reading or soreness checklist cannot rule out injury.
