endurance help

hey nancy first off thanks for your advice, but i what did you mean by "drive to the wall on EVERY finish"? and also, it seems like certain days i can swim all day, and others i cant even do a 100 without having to catch my breath after 50, could this be because im not eating right? it isnt something ive gave much thought to but going from a pretty lazy life style that i had to swimming about 2 hours a day 5 times a week, should i consider changing my diet some? By "drive to the wall", I mean swim 100 yards on a 100-yard swim, not 99 yards. No coasting in, either. Swimmers do need to eat well and rest to get the most from their practices. Swimming can burn a lot of calories in general and carbohydrates in particular. Check the USA Swimming website; they have some good nutrition advice for swimmers. http://www.usaswimming.org
