Getting in shape for the summer and receiving frame-worthy timing results are nice and all, but for some people the schwag is a pretty solid reason to run the Bolder Boulder 10K, too.

Race organizers have put together packages of merchandise for racers this year that include a $10 gift card to Dick's Sporting Goods, a reusable snack pack -- whose contents will be unveiled after the race Monday -- and, of course, there's the post-race beer.

Racers had five packages to choose from this year, ranging from the basic T-shirt package to the "Bolder" package featuring all three shirt options and a pair of Crocs.

While packages are still being assembled for late entrants at the Pearl Street Mall's sports exhibit this weekend -- an $8 procrastination fee applies, $13 the day of the race -- Bolder Boulder director Cliff Bosley estimates 36,500 packages have already been put together for registered participants.

"Each packet is a custom packet with (the runner's) bib, official merchandise, calendar/runner's guide and any coupons they purchased," said Bolder Boulder marketing director Matt Jenkins.

Of course, the T-shirt remains the centerpiece of the package. Over the race's 31-year history, Bolder Boulder shirts have become a part of the event and city culture.

"They represent the personality and tradition of the race. We are very proud when we see people wearing Bolder Boulder shirts around town or even in other states or countries," Jenkins said. "A lot of effort goes into choosing our designs every year and includes focus groups and design work from a top creative company in Denver."

This year's shirt designs were produced by Denver's Genesis Inc. The company also designed the running man logo for the inaugural race in 1979.

Older shirts are still widely sought in local vintage clothing and secondhand stores.

"I've never seen one sit around long," said Marika Evanger, manager at Boulder's Buffalo Exchange. "When they come in, they go pretty quick and people usually have a story about them."

Jenkins said the race shirts remind people of their "triumph" every time they wear them.

"My mom still has one from before I was born," said 19-year-old Boulder resident Anya Frans. "She was a marathon runner. I think it's kind of like a trophy."

Frans, who will participate Monday, collected her first Bolder Boulder shirt last year.

Harry McClusky, 66, ran the race with his wife in 1983 and, though he no longer wears it, he keeps the shirt as a keepsake.

"We ran it with friends, and we really enjoyed it," McClusky said. "It was such a big race -- a really neat race."

Organizers have printed several thousand surplus shirts in anticipation of weekend registrations. Those left over will be donated to humanitarian aid charities after the race.
