You know how every offensive lineman in the NFL seems to be like 400 lbs. nowadays? (like that is something to be proud of) It seems every distance runner is super light. I was watching Carlsbad last night and they were saying Motteram was huge at 6'2" and 142 lbs., which seems like a bit light. Doesn't Culpepper list himself as 6'2" 130 lbs.? I know he is light but 130 at that height? Now you know women are lieing about their weight, they always do.
Looking at some of the USATF bios, I'd say that some distance runners do.
I think a lot of the women do. Add 5-10 lbs. For actresses at 15 lbs. Ha!
Culpepper is listed as 130, 6'1". But he really is freakishly thin. I was just over 140 at a similar height straight out of high school, and he has a thinner frame than I had. In fact some of the guys are listed at weights and heights that seem a bit heavy -- for example, Broe at 175.
Most of the women are listed at around 110lb in the USATF bios. For a skinny distance runner who isn't very tall, these numbers seem plausible.
I always assumed I was heavier than I actually am. Thought I was 127 or so but I was just accurately weighed for a study and it turns out I'm really 119. I am a 5'9" male. Perhaps elite runners just don't know what they weigh, and the values in their bios are estimates or are based on ancient measurements. I run for a D-I team and my teammates and I never weigh ourselves because we don't care about our weight.
Yeah it depends on the person. A lot seem off though. Don't pay attention to those #ers...they're meaningless, some times lies, guesses, or accurate.
