My daughter's rescue Greyhound having the time of her life at the beach. These dogs run FAST and even though she was coming straight at me at full tilt, the AF tracking nailed her every time. Greyhounds can reach a full speed of 70 kilometres per hour (43 mph) within 30 metres (98 ft), or six strides from start, traveling at almost 20 metres per second (66 ft/s) for the first 250 metres. So you can imagine she was really travelling as she was an ex racing dog ans won a few races.
