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
PUZZLE
It is truly amazing the speed at which Olympic atheletes run the 26.22 miles of the marathon. In his hayday the amateur runner, NogNod, could run a flat mile in 5 minutes 25 seconds. This sounds pretty quick, until you realise that even if he waited, fresh and rested, one mile from the marathon finish line for the leading athletes to arrive, he still could not beat them to the line ! even though they have already been running for 2 hours. Good grief.
Here is the puzzle.
An amateur athlete waits, fresh and rested, exactly 1 mile from the end of the 2008 olympic marathon. When Samuel Wansiru of Kenya arrives at his position the amateur starts running for the finish line along the route. He reaches the line in 5 mins and 25 seconds. Wansiru wins the gold in a time of 2hrs, 6 mins and 32 seconds. Assuming Wansiru runs the whole race at a constant pace, how many seconds behind him does the amateur athlete cross the line. Assume the course is 26.22 miles exactly.
