"They are physically ready," said Block. "They are mentally prepared. Many of them had a rest week this past week and are ready for some big performances."
The three-day championships begin Thursday at Choccolocco Park. The only events scheduled for opening day are half of the decathlon, half of the heptathlon, the women's hammer throw, the men's hammer throw, the women's 10,000 and the men's 10,000.
"Our whole strategy and training year is based around this final competition," said Block. "Our secret to success is to be staying in the moment and winning each race one step at a time."
Block said he expects fast time for the runners and new personal bests all around.
"The surface of the track should be fast," said Block. "The field event areas should be nice and new and clean. The throwing facilities will have new concrete. We're looking forward to this. There's nothing like running on a new facility."
On Friday, the field events begin at 1 p.m. with the men's long jump and the women's high jump. The track events begin at 3 p.m.
Block said stretching the outdoor championships to three days for the first time will change some team strategies.
"We're able to spread people around and have them compete in a few more events than they would otherwise," he added.
