This is the bonus cache for the Whitchurch! Adventure Lab Series, which involves a walk of around 2.5km both on and off road and which could be muddy in places. Please note that part of the trail goes along a footpath which is strictly NO CYCLING, so please leave your bikes in the car!
To obtain the co-ordinates, you will need to complete the series, collecting the Bonus clues as you go.
Then substitute the number into the following formula: N 51° 13.(A+E)(C+D)(B+D) W 001° 20.(E-B)(B+C)(E-A)
You will get a hint when you complete the walk.
Here's a linky to get to the Lab Caches - you will need a smartphone to access the Lab Cache App. Whitchurch!
Enjoy the Walk!
P.S. I'm sorry about the location of the cache, but that is where I was allowed to place it!
