Start your trip at the co-ordinates on the listing - and make sure you have access to your ‘picture map’ before you go, although it can be done without the map!!
At each stage collect the required digit for the next stage then key converted co-ords into your GPS. You can determine the approximate location of subsequent stages by following the picture map. Collect and keep all digits as you will need them to complete the circuit.
It’s not as complicated as it may look and is ideal for those inevitable rainy days where you can stretch the ‘old grey matter’ more than the legs - although it is only around 10 miles 
- nice one on the bike too ENJOY!
