How accurate should i input weight?

[Machoman121]

To improve realism do I also factor in water bottles, GPS, Helmets, Back pack (car keys, sunglassess, gel, food, cakes)....At the moment I have included my body weight only and the bicycle weight. In real life i have all those other stuff which can easily add up. Will adding up all these stuff improve the accuracy of the software to simulate real life?

If you want more "realism" I would be more concerned about what trainer are you using and how accurate is power reported by it (unless you have separate power meter). As for the rest: when you're outside there are factors like road surface, temperature/humidity, wind etc that might affect your riding time way more then weight of gels so I would not worry about it. To get a better perspective you can play with weight in online bike calculator http://bikecalculator.com and see how it changes the speed. The rest is up to you.

For my part, I consider the effective total weight :
- fully equipped cyclist (shoes, clothing, helmet ...),
- fully equipped bike (with 2 full bottles, pump, saddle bag, GPS computer...).

Taking this into account, I made a comparison between the real and the virtual ascent of l'Alpe d' Huez with excellent results :

All weight makes a difference, at least on hills. It's just part of the math. But I would not obsess about it. If you want to get an idea if your performance is actually changing, just be sure the weight setting remains constant, unless, of course, you happen to be actually gaining or losing body weight.
