The cache is at the posted coordinates, but you must meet the challenge qualifications in order to log a find.
Find at least one cache each in 6 of 11 distances from your geocaching home coordinates to qualify for this challenge.
1 mile to 10 miles
10 miles to 25 miles
25 miles to 50 miles
50 miles to 100 miles
100 miles to 250 miles
250 miles to 500 miles
500 miles to 1000 miles
1000 miles to 2500 miles
2500 miles to 5000 miles
5000 miles to 7500 miles
More than 7500 miles.
(Note: The category "less than 1 mile" is not used in this challenge for privacy reasons).
To qualify you can make a list of caches with their distance categories in your log, make a bookmark list or post a screenshot of your graph. Unless your statistics are public, in that case you don't have to do anything.
If you would like to go with metric distances that is fine too.
The difficulty rating is for the challenge. The final is 1D/1.5T
