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!


The nutritional aspects of training and competing in endurance events is huge. I don't talk about it much in the main blog as I think people would find it extremely boring! For those who want to know more I'll put it here.

To give you an idea of what's involved here's a picture of my cupboard.

Each one of the pots is filled from much bigger bags that have to live in the shed!

It's easier to present much of the detail on my website

The aim is to get all the little bits of information together into something useful.
Protein is there now.
Carbohydrate and carbo loading to follow soon.

Calcium and Vitamin D
My race day nutrition since 1997

I started off triathlon in 1997 with Mars bars sellotaped to the luggage rack of my mountain bike. This had to change unfortunately as I like mars bars. 

1998 - 2002 Gels for olympic triathlons

2003 Caffeinated gels for same

2004 Power bars (on bike) and caffeinated gels (on run) for half ironman western australia

2005 Same for first ironman with some salt tablets on run and lots of de-gassed cola 

2006 - 2008 Perpetuem (http://www.hammernut.co.uk/perpetuem-13-c.asp) (on bike) for ironman UK with caffeinated gels on run 

2009 Ironman UK and Etape - High-5 energy drink (energy source 4:1 Carbohydrate:Protein) on bike and caffeinated gels on run, with High-5 energy source xtreme carbs in hour up to swim start. 

2010 Ironman UK - As for 2009 but not the 4:1 mix, just 2:1 Glucose:Fructose

2011 Ironman UK - I made up my own drink from scratch. Recipe:
Branch chain amino acids
Table salt
Green tea extract
Potassium phosphate

July 2011 - thoughts on my diet:
1. Carbohydrate
I continue to make changes - trying things out that I hear about and also applying what I know about physiology and biochemistry.
At present, probably off the back of the Atkins diet a diet called the paleo diet is becoming popular with endurance athletes. Essentially this attempts to mimic how stone age man would have eaten - it's lower in carbs and avoids wheat and dairy. It's championed by Gordo and Joe Friel who are pretty big names.
Needless to say there is no way I would try anything like it but it did kick me into action to get my biochemistry books out and see whether the "more is better" approach with carbohydrate that most people adopt is maybe not so wise.

What is accepted is that your ability to burn fat is what's important.
I am reading "biochemistry for the medical sciences" - and should have something useful to say in day or two. This is now done and i'll put it on my website - http://web.me.com/jkmoon/mysite/Welcome.html
