Calories Burned Walking Half Marathon

Estimates based on a moderate pace (3.0 mph) using the MET calorie method.

Walking burns roughly the same calories per mile as running — it just takes a little longer. That's the beauty of it.

What Walking a Half Marathon Actually Feels Like

A half marathon is 13.1 miles. Walking one takes 4–5 hours depending on your pace. That is a serious undertaking — but absolutely within reach for a dedicated walker who has built up to it steadily.

Many half marathon events have a walk-friendly time limit of 4–4.5 hours, meaning a consistent 3.0–3.3 mph walking pace will get you to the finish line within the cutoff. Check your event's specific time limit before you sign up.

Training for a walking half marathon takes 10–16 weeks if you're starting from a regular 5–6 mile base. The goal is getting comfortable with 10–11 mile training walks in the weeks before the event. Your body will adapt. Your feet will get stronger. Your pace will find itself. A half marathon walk is an achievable goal — and crossing that finish line is something genuinely worth doing.
