Your total cache-to-cache distance must be equal to or greater than 400,000 kms
The Rules
1. Caches can be of any cache type, and can be found anywhere in the world.
2. Past finds will count. If you have done this achievement in the past, you do not have to do it again.
3. You are welcome to find the cache before completing all of the requirements. If you do, please just sign the log and post a note on the cache page. Then, after you have completed the challenge, you can come back and log it as a find.
4. Logged finds that do not qualify will be deleted.
