The world’s lakes are some of the most beautiful places on our planet and time spent on their shores is precious. Have you ever toyed with the idea of walking around the world’s most beautiful lakes and starting in your home country? Then the Iron Lake Challenge is just the right challenge for you!
With our challenges, we want to encourage you to spend a good time in the fresh air, get moving and get to know the most beautiful lakes in the world. Combine your openness for new things, love for sports and traveling and become a worldwide Iron Lake Runner/Hiker. You will collect valuable life moments and spend quality time in nature.
We use the majority of the proceeds from the entry fees to finance new tree seedlings for the worldwide reforestation of forests! Our “Why?” is to protect or replant one million trees worldwide.

How does the Iron Lake Challenge work?
Below you will find an overview of all currently possible Find Iron Lake Challenges. In the Iron Lake WORLD Challenge you can circumnavigate all lakes worldwide to earn the coveted collector’s medal. On the respective “Local Lake Challenge” pages you will find the lakes that you have to circumnavigate on foot in order to complete the challenge. You have as much time as you want from the time you register, because you should enjoy yourself and not rush. Basically, the Iron Lake Challenge is structured in such a way that you have to circumnavigate the ten largest lakes in an area. However, from time to time it may be “just” one large lake. Let yourself be surprised!
Upload a copy of your tracking into our tool or send it to us by email and we will send you the respective Iron Lake Challenge medal, the matching marble of the Timeless Challenge and the advertised Life Score points. The beautifully designed medals are real collector’s items and an ornament for any medal board.
More information and explanations can be found on the rules page.
