Kuala Lumpur (CNN) -- Launching off a 300-meter-high tower platform with only seconds to pull your rip cord might sound like the act of an insane person.

But that's exactly what 103 base jumpers from 20 countries -- presumably all of sound mind -- did in Malaysia over the weekend.

The jumps were part of the annual KL Tower International Jump 2013, held in Kuala Lumpur from September 27 to 30.

Kat Donahue, 32, a location manager from the United States, was one of six women jumping this year.

"A lot of people do say I'm crazy but my family is pretty supportive," she said.

"Jumping can be scary, but when you calm your nerves and become quiet it's very peaceful out there, meditative. Base jumping can be solitary but this is such a social event, it's great."

This year's jump also welcomed Sean Chuma from the U.S., a pioneer in tandem base jumps, and Lonnie Bissonnette, a paraplegic base jumper from Canada.
