K2 Dermatology is a 2025 Gold Sponsor of the Columbine Mile Marathon at Columbine Elementary School in Boulder.
What is the Mile Marathon?
This amazing one-mile run for Columbine students started in 1977, and is even one year older than the Bolder Boulder! Rich Castro, one of the founders of the Mile Marathon, figured out the Mile Marathon is the longest running children’s foot race west of the Mississippi.
It is fun for the children and at the end students get to sign each others shirts!
