I have been running recently for a half marathon and the thought of doing a full marathon makes me think idk if I'll ever get there but a fucking iron man to me I just don't understand how that is phiscally possible for an human being to actually complete. How this thing thinks she can do a half she is out of her mind. If you could actually complete a half iron man there is no possible way to be fat. I burn between 1200-1500 cal every time I run my 13.1. If your doing that with 50 something mile bike rides and 2 mile swims you looking at 2500-3000 cal how you can train for that and be even overweight you have to be consuming unreal amounts of food. So I 100% agree with you!
