Last year I managed a Geostreak of 51 consecutive days of finding a cache, and this cache is located at the above co-ordinates, however, in order to log this cache, you must successfully find and log at least one cache per day for 40 consecutive days!
All forms of caches (traditionals, unknowns, multis, earthcaches, wherigos, events, virtuals, webcams and letterbox hybrids) can be used in this challenge.
You can of course, as for all challenge caches, find the cache and add your name in the log book before completing the challenge. You can write a note to say where you are in the challenge and then when you have completed the challenge log a find and gain your smiley.
There is a small pull in for one car by the caches location.
There is a FTF prize which is for the first cacher to have completed the challenge and found the cache.
Out of interest UK cacher Mario McTavish geostreaked for 1500 days!
