Oscar Rando of Spain is losing weight by walking and running the full length of Spain â€” almost 2,000 miles. Sponsors are donating about $3 to charity for every gram of fat he loses. For some perspective, there are 454 grams in a pound. The charity he chose â€” Gats â€” helps disadvantaged local people find jobs, something much needed in Spain, where the unemployment rate is 25 percent. Rando has lost more than 50 pounds.
