Quick answer
A mule deer can reach about Up to 48 km/h (30 mph); stotting escape gait in short bursts. Terrain, motivation, and body condition (Bucks 55–150 kg; does 43–75 kg) all change the number you would measure.
Key takeaway
A mule deer can reach up to about 48 km/h (30 mph); stotting escape gait in short bursts. Terrain, motivation, and body condition (Bucks 55–150 kg; does 43–75 kg) all change the number you would measure.
Mule Deer top speed
Published estimates put mule deer speed near Up to 48 km/h (30 mph); stotting escape gait. These are usually peak sprint figures, not cruising speeds held for long distances across Western forests, sagebrush, deserts, and foothills of North America.
Sprint versus endurance
Most animals accelerate hard for capture or escape, then recover. Open ground favours higher recorded speeds; dense cover favours agility over raw pace.
Anatomy behind mule deer speed
Limb proportions, muscle fibre mix, and mass (Bucks 55–150 kg; does 43–75 kg) shape acceleration and top end. Heavier individuals may hit hard but tire sooner.
Reading speed claims
Methods differ (radar, filming, anecdote). Prefer ranges from recent field studies over viral single numbers, and never try to outrun wildlife.
Conservation status
Listed Least Concern overall, but some migratory herds face declines from habitat fragmentation, chronic wasting disease, and severe winters. Wildlife crossings and protected winter range help maintain connectivity in the western United States and Canada.
Stotting and escape behaviour
When alarmed, mule deer often flee with a four-legged bounce called stotting, which may signal fitness to predators or improve visibility over brush. This gait distinguishes them from the running gallop of white-tailed deer.

Odocoileus hemionus — used in research and conservation listings for mule deer.
What do mule deer eat?
Mule Deer eat browse, forbs, grasses, and acorns, with seasonal and regional variation in Western forests, sagebrush, deserts, and foothills of North America.
Where do mule deer live?
They are associated with Western forests, sagebrush, deserts, and foothills of North America. Local presence depends on food, cover, and human land use.
