At the posted coordinates you will need to locate the memorial paver of Sgt. Shock. To obtain the final coords you will be using the stone to the LEFT.
You will only be using the six digits (•/•/••••) on the second line of the paving stone.
N41 AB.0CD (A=1st digit) (B=5th digit minus one) (C=3rd digit) (D=4th digit minus 2nd digit)
W90 W0.XYZ (W=3rd digit plus 6th digit) (X=6th digit plus four) (Y=1st digit plus two) (Z=4th digit minus four)
Log only, no room for trade items or trackables in this one. Please replace as if it were your own hide. Muggles passing by could accidentally find this.

The tug of war event was held at the Olympics from 1900 to 1920. Tug-of-war was always contested as a part of the track & field athletics program, although it is now considered a separate sport. This may seem like an unusual Olympic sport, but in fact it was part of the Ancient Olympics, first being held in in 500BC.
