Mo Farah had to work hard to advance in the men's 5,000 meters.

Back on the track at Olympic Stadium, where he dazzled the crowd on Saturday night in winning the 10,000 meters, Farah was cheered wildly in his opening heat. He thanked the crowd after the race, in which he had to push down the final straight to finish third. The top five finishers in the heat advanced. The finals are Saturday.

"It was pretty difficult, bit tired today," Farah said after the race. "It's all good. I got great support from the crowd. The pace kept going up and down, that's what happens in the heat."

Farah repeatedly praised crowd support and credited the fans for pushing him to his uplifting win in the 10,000. He said he'll go for gold again in the finals.

"I am going to go out there and give 110 percent, that's all you can do," he said. "But it's all about what my legs allow me."
