The "100K Challenge" is a fundraising initiative aimed at raising $100,000 for various charitable causes. Participants engage in activities such as running, walking, or cycling to encourage donations from friends, family, and community members. The challenge promotes physical fitness while supporting important social issues. This challenge often involves teams or individuals who set personal goals and share their progress on social media. By leveraging platforms like Facebook or Instagram, participants can inspire others to contribute and join the cause, creating a sense of community and collective effort toward achieving the fundraising target.
