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!
