@daveh – yeah I know. I hate driving to work though so I don’t really mind, I just find it soul destroying sitting in rush hour traffic, much rather be on my bike.
@mikey74 – I did play around with a HRM a bit a few years ago, found it a faff to use though and variations in traffic, road conditions and weather made it quite hard to interpret the results.
I’ll take a look at that SIS Nocte stuff, can’t do any harm to try it out I guess.
So what I need to do is train harder/better and get fitter so I have some energy at the weekends, then it will take less effort during the week to commute at the same speed and I’ll be less tired?
