A month or so back, I had a warning from 2 good friends (obviously worrying about my welfare rather than bottling out of this endeavour themselves. Yes Iain and Graham - you know who you are, and thank you!) about the duration of a longer triathlon than the Southam Sprint event. That got me to thinking about what the issues could be .....

 

Fitness / Stamina

Whatever it's called, we need to be able to go the distance and be familiar with a 1200m swim, a 56km ride and a 13.1 km run, and then putting it all together. Gulp.

 

Hydration

I sweat a lot so I'm going to need to do more investigation on this subject - liquids plus electrolytes/salts whatever.

 

Nutrition

Just going off what my Suunto tells me about calories .....

The 5k parkrun uses about 550, a 20k road bike ride claims about 700, the Southam sprint tri was worth 1300 kCals excluding the swim (the HRM doesn't work underwater) which substantiates the individual discipline calorie costs. So I'm missing swim data but the other 2 legs are going to burn around 2000 (56k ride) plus 1450 (13.1k run).

For now I'm going to guess the swim burn rate at lower than running because I don't feel so knackered afterwards, so I'll estimate 500 for that, giving a total burn of just under 4000kCals for the 70.3. That sounds like a lot of jelly babies !!!  :)

 

Anyone else thinking about this???
