Bob Cooper (born 1954) is an American freelance journalist, a contributing editor for Runner's World, a former executive editor of Running Times, a competitive long distance runner, and a longtime San Francisco Bay Area resident. From 1980 to 1990, he held various editorial positions for Triathlete, Inside Triathlon, and City Sports magazines.
Cooper started running in 1969, and since then has achieved a great deal of success as a competitor. As an ultramarathoner, his fifty mile time of 5 hours and 42 minutes ranked seventh in the US in 1977. He also has run seven sub-2:30 marathons. As a teenager, he was part of a truly cross country relay in 1973 that traversed the breadth of the United States from the Pacific Ocean to the Atlantic Ocean. During another such relay along the Pacific Coast, from Mexico to Canada in 1981, he ran a dozen two hour legs in a little over nine days. He is believed to be the only runner to ever participate in relays spanning the length as well as the width of America.
Cooper's top performances include a win at the Silver State Marathon, second place at the Tucson Marathon and the American River 50 Mile Run, third place at the San Francisco Marathon, and fourth place at the US 50 Mile Championships. Since turning forty, he has won numerous masters titles around Northern California.
