No idea Stagger... I am of the opinion that in order to get better at cycling you cycle and in order to get better at running you run... Never been to a gym in my life

My cycling today was about 45 minutes in a field with sheep in jumping on and off the crosser in different ways and perfecting mount/dismount at speed as well as picking up and carrying the bike to jump over planks and shoulder it, put it down and re=mount... bliddy hard work!

I also found out the advantages and disadvantages of the field with sheep:
Advantage: short grass
Disadvantage: you and bike get covered in sheepshit :-O

Oh and did 2.5 hours on the track yesterday as well, feeling terribly unfit and my @rse is now sore too! It is amazing how quickly you get dis-used to riding and unfit as a result :-O
