Karin is a Chilean ultrarunner, bikepacker, and environmentalist who finds joy in sweating it out while picking up trash. She’s explored trails across places like Australia, Indonesia, and Chile, usually with a cleanup bag strapped on and a big idea brewing. When she’s not out plogging, she’s probably sketching birds or mapping the next offbeat adventure somewhere wild.
