Some scary sessions there - the shear pace of yours Dean, the number of reps of yours Johnas and the shear complexity of yours SS!!
Ah, the old Branta canadensis and the shear productivity fo their rear ends! I once spent a year of my life trying to prove the hypothesis that the quantity, and quality, of their shit could turn a bog standard, but ecologically rich, lake into a quagmire of cloudy, decaying and ultimately lifeless puddle...
Instead of the lake I chose, which is sandwiched between the M25 and the A3, I should have chosen the Goose Shit track in Barnes - at least I could have done a bit of useful training at a time of my life when I was more interested in training only to drink disgusting lager!
