This series of 65 puzzle caches has been placed to celebrate the London 2012 Olympics and Paralympics. Each ring is set by different cachers and contains 11 or 12 hides plus a bonus. The whole design is over 4km across. You will need to find all caches for a ring in order to find the bonus and complete the ring.
There are three Medal caches above the rings, Bronze, Silver and Gold. See the Bonus cache descriptions for how to find them. See the Gold Medal cache page for full series credits.
The Sussex Olympics Rings Team is: NogNod, Tootsie's Trackers, Cachedragon, Martletsman, ProfTonks, AnTsInRpAnTs & Lost!
You can do all the black ring caches in a single walk. It's not a loop, but it should link with caches in the yellow and green rings. If you do the black ring caches in reverse order, you'll have to double back for the bonus.
This series is now featured in issue 10 of The Seeker the magazine of the Geocaching Association of Great Britain. See this link
