One door closes… another one opens
Welcome to the 2026 KFF Marathon Challenge!
The KFF Marathon Challenge, a year-long activity wherein we will recognize the achievers who work, or activate, the most KFF References during the calendar year, is designed to promote WWFF activity worldwide and to recognize those that distinguish themselves by working, or activating, the most KFF References during year. The KFF Marathon Challenge wants to continuously draw attention to the importance of protecting nature, flora and fauna. And to encourage hams to Make Nature Your Shack.
Good luck to hunters and activators during these great propagation conditions!

2025 was another great year for the KFF Marathon Challenge. We have new leaders in two of the categories, Laurent W0MM and Kerri KB3WAV. And Gerard F1BLL continues his domination in the DX Hunter Category. Congratulations to the three of you!
