It's a prize that cost hours of summertime sweat.
And the T-shirts that reward the most dedicated participants of Red Dog's Dog Days, Lawrence's public summer workout, have become a hot commodity.
"I go back to work, and everyone has one. It's a big deal," said Kendra Anderson, a Prairie Park School music teacher.
Don "Red Dog" Gardner's crew keeps expanding. More than 800 people earned the shirts this year. They had to attend at least 25 workout sessions this summer.
Dozens on Friday took part in one final noon workout for this summer outside Kansas University's Memorial Stadium. Hundreds more gathered to get their hands on their deserved shirts after showing their appreciation for Gardner, his wife, Beverly, and their nearly 30 helpers.
Gardner started the workouts in 1984, and they have grown immensely, especially in recent years.
"Each year, I think it's because I'm getting old, but it's sad because you see these kids and people, and they move on," he said. "But it's the end, and I'm one of those guys that comes right back ready to go again."
Dog Days once again appealed to people of all ages who wanted to improve their health and get in shape, Gardner said.
Owen Blackwood will be a sophomore at Lawrence High School. He needed a venue for summer conditioning before football season.
"It's a great feeling. It's like a relief," Blackwood said of getting his T-shirt.
He also plans to let plenty of people know what he achieved.
"Oh yeah, first day of school," he said of wearing his Dog Days T-shirt.
The final session was outside the stadium Friday because of the start of KU football practice. Gardner said the stadium is a major draw for participants, but he understood KU's position. He said he would work with KU on planning to return the workouts to the stadium for next summer.
The summer workout sessions are the most popular, but Gardner will go back to work next week.
He'll lead a fall session at 6 a.m. and 6 p.m. Tuesdays and Thursdays northeast of Memorial Stadium. The sessions run into November.
There's also the Boys and Girls Club's Red Dog Run at 8 a.m. today at the Kansas River levee to raise funds for the club.
