[header] How to survive an encounter with an ostrich [title] Run for nearby cover. [step] Expect ostriches to attain speeds of 43 mph (70 km) over open ground. If there is dense vegetation or woods close enough for you to reach before the ostrich reaches you, sprint for that. 
Prevent the ostrich from attaining optimum speed so it has less chance of outrunning you. [substeps] If there is more sturdy cover than vegetation (such as a car or manmade structure), go for that.
