About 1,000 anti-war protesters marched to the site of the Democratic National Convention Sunday in Denver, in the first of at least five such rallies planned this week by the group Recreate 68.

The rally began with just a couple hundred demonstrators Sunday morning outside the Colorado State Capitol building, but swiftly grew as they began their trek toward the Pepsi Center, which is under heavy security with the convention set to begin Monday.

Activists like Cindy Sheehan kicked off the event with more than two hours of speeches.

"We're out here to speak out about the. . .destruction of society and the impact on our own society as we have fewer and fewer resources," Denver local Jane Cahn told FOXNews.com.

She and her husband Eric said they have joined in on such rallies for 40 years.

"This is one of the primary gatherings [this week] that's expected that's for peace," Denver resident Susan Stark said.

Participants Alison Jane and Joshua Marks traveled from St. Louis, Mo., to attend the demonstrations.

"We're young kids and we don't want to see our futures turn into s***," Marks said.

Colorado Springs resident Bryan Ostren said he mostly heard of the events through word of mouth. He said Americans have the freedom to use their voices to end the war.

Though demonstrators joined under the common cause of ending the war, they also spoke out in favor of abortion rights and against torture, imperialism and the election process.

"I think [the Re-create 68 events are] going to get everyone together and feeling the same thing," Ostren said.

Meanwhile, police officers in riot gear patrolled on bicycles and foot along the route.

The protesters marched as thousands of delegates, reporters and politicians descended on the Western city.
