Welcome

I started this blog in 2010 when there were 11 weeks to go before my next Ironman triathlon. People have found it interesting (mainly my Mum!) so I continue to write.
The Ironman is a long distance triathlon; Swim 2.4miles, Cycle 112miles, Run 26.2 miles (marathon). I have competed in one every year since 2004. I hope this blog can help others see what is involved. I find the process of writing it makes me more accountable and motivates me to do the harder sessions when i'm not feeling like it!

Using the spin scan to see how efficiently I am pedalling - seem to hover around 85/100 can get it as high as 97/100 but not for long. This is a measure of how evenly the back wheel is spinning and reflects therefore how evenly you are pedalling. Beginners will tend to stamp on the pedals a get very low numbers - a very peak and trough bar chart, or a less round nyquist plot below. Lance Armstrong is probably in the high 90s all the time - an almost flat bar chart.





All this fancy stuff however can be done on the bike by just listening to the back wheel, your trying to eliminate the oscillating sound and create a continuous one - that is just as good.
