Which is better for your joints: walking or running? Dr Pankaj Walecha explains it may depend on what you do before that

The Joint-Health Question Most New Runners Ask Backwards

Indiadailyupdate.com – Across India’s metro cities, the landscape of recreational athletics has shifted dramatically over the past decade. Running clubs now operate in neighbourhoods that once had none, 5K and 10K events fill weekend calendars, and tens of thousands of participants line up each year for marathons in major urban centres. What was once the exclusive domain of elite competitors has become a mainstream weekend pursuit for office workers, students, and retirees alike.

Yet orthopaedic surgeons watching this surge from clinic chairs see a pattern repeating itself: the person motivated enough to lace up running shoes and physically capable of doing so often arrives with a musculoskeletal system that simply has not been conditioned for the repetitive impact of running. Dr Pankaj Walecha, an orthopaedic surgeon, frames the issue not as a binary choice between two activities but as a question of readiness and progression.

Reframing the Debate

The most common question older adults pose to their doctors is straightforward: which cardio option is gentler on the knees, walking or running? Dr Walecha argues that this framing misses the point entirely. The relevant inquiry, he explains, concerns whether the joints, muscles, and tendons have been conditioned to absorb the specific load an activity imposes, and whether that load is being escalated at a rate the body can actually adapt to.

“What matters is whether the joints, muscles and tendons are conditioned to handle the load being placed on them, and whether that load is being increased at a pace the body can adapt to.”

Running undeniably places greater mechanical demands on the lower limbs than walking. Each stride incorporates a brief flight phase and a more rapid transfer of body weight through the skeletal and soft-tissue structures. That distinction, however, does not translate into a verdict that running is inherently destructive to healthy joints. It translates into a requirement: preparation.

The Preparation Gap

A person who has spent months or years largely sedentary cannot assume that completing a five-kilometre walk signals immediate readiness for five kilometres of running. The cardiovascular system often adapts far faster than the supporting connective tissues, creating a window in which a new runner feels perfectly capable mid-workout only to develop knee, shin, or tendon pain hours later.

“The lungs may cope before the supporting tissues do. This is one reason new runners can feel perfectly capable during a workout and develop knee, shin or tendon pain afterwards.”

This physiological lag is precisely why Dr Walecha positions walking as the sensible entry point for most people returning to exercise, carrying excess body weight, or emerging from a period of inactivity. Regular walking builds a substantial cardiovascular and muscular base without immediately exposing the lower limbs to the higher-impact forces of running.

“Brisk walking, longer walks, and incline walking can progressively challenge the cardiovascular system while also giving the lower limbs time to adapt.”

Strength Work Is Non-Negotiable

Treating walking as a complete substitute for resistance training is a mistake Dr Walecha flags explicitly. If the eventual goal is running, the preparatory programme must include the muscle groups that govern the knee, ankle, and hip. The quadriceps, hamstrings, glutes, and calf muscles all participate in absorbing and controlling ground-reaction forces during locomotion.

“Basic strength work such as squats, step-ups, calf raises, hip strengthening and controlled single-leg exercises can therefore be more valuable than simply adding more kilometres.”

This guidance carries particular weight for individuals with a history of knee pain or diagnosed osteoarthritis. A joint diagnosis does not automatically mandate complete activity avoidance. In many clinical scenarios, the more productive strategy is to identify the activity level the joint can currently tolerate and build incrementally from that baseline.

“Walking may be more comfortable during a painful period, while running may need to be modified or temporarily avoided depending on symptoms and function.”

The Run-Walk Method as Load Management

For those whose ultimate aim is continuous running, Dr Walecha highlights the run-walk interval approach as a practical bridge. Rather than attempting unbroken running from the first session, a beginner alternates short running intervals with brisk walking breaks. Over successive weeks, the running segments lengthen as tendons, bone, and connective tissue adapt. The method also eliminates the psychological pressure to interpret walking breaks as personal failure.

“For many recreational runners, they are simply a sensible way of managing training load.”

The same graduated principle extends to individuals using exercise as a component of weight management. Walking, being lower-impact and easier to repeat consistently, often serves as the safer initial modality while the body builds the structural resilience needed for higher-intensity work.

The Core Mistake: Pace, Not Activity

Dr Walecha distils the most frequent clinical presentation among new runners into a single observation: the problem is rarely the activity itself but the speed at which volume and intensity are escalated. A typical pattern involves signing up for a 10K, beginning four or five running sessions per week, and rapidly increasing distance because the first few workouts produce a noticeable cardiovascular improvement.

“The cardiovascular system can improve quickly, creating a false sense that the entire body is ready for the same progression. Tendons, bones and other tissues adapt more gradually.”

“For new runners, the biggest problem is often not running itself but doing too much too soon.”

The practical implication for anyone considering either activity is clear: the question is not which exercise is inherently safer, but whether the individual’s current tissue conditioning matches the load they intend to impose, and whether the progression plan respects the slower adaptation timeline of bone, tendon, and ligament relative to the faster gains available to the heart and lungs. Answered honestly, that question resolves the walking-versus-running dilemma without requiring either activity to be abandoned.
