If I weigh myself before and after a 12 mile run in hot weather I loss 3 - 4 pounds in weight.....is that 'norma'l? I would have a couple of gels during the run.
These are fancy bathroom scales that also show your body fat and body water content. My body water figure has increased slightly after the run which seems odd.
