thanks MichaelW
you are quite right about putting in the miles. I wish I could.I would love to bike to the gym twice a week but that would take about 2 hours out of my working day instead of just one
My problem is twofold. I work from home so have no opportunity to commute and I do not have the time for regular long rides. I will have to pack a lot of high energy exercise into the shortest possible time if I am to achieve anything.
