Hi Guys, I appreciate your thougths and responses!
My first race in May is an 800 meter open swim, 30K bike and 5K run, but I'm also considering an olympic distance later in the year, and will be doing longer (2-4 hour workouts).
My normal routine is to NOT eat anything before working out--not because I think there's some great weightloss/calorie burn benefit, but because I'm just not hungry and generally don't feel good with something in my stomach before I exercise. My work schedule is really variable (work 7pm to 7am, 3-4 days a weekm so some days I'm up at 9am and some days that's when I'm going to bed) and my body gets confused what day/time it is...which is why I basically went to a "eat only when hungry" plan a few years ago.
No, no one is telling me to eat/nothing I read...I'm just going by my last few workouts and how I feel. I've either felt a energy crash or feeling icky right afterwards, which is new for me. I've definitely worked out for more than an hour and been fine before.
Examples: Ater my second swim, I got out of the water and felt nauseous the entire day. I drank water before/after the workout but didn't eat anything beforehand. After talking with people, I decided to eat a banana beforehand and makes sure I drank water during the swim, which helped a lot (only felt slightly dizzy for 10-15 minutes after and no nausea). I've swam twice since then (both for one hour) and done the same thing, which seems to have solved the problem. (but I definitely feel hungrier in general after I swim)
Yeserday I went for an hour bike ride, with nothing to eat beforehand. I felt ok during the ride, but I had to fight a lot of wind on the way home and was pretty tired--I had wanted to ride for another hour but it started raining and I'm a wimp

. After being home 15 minutes I had a big energy crash and felt terrible.
I'm just thinking that if I would have eaten beforehand/had a gel on the bike maybe I would have felt better and able to ride longer.
My general nutrition is really good and I have no problem eating really balanced and healthy meals during the day.
I guess like everything else, I'm finding that it's trial and error and we're all different. Thanks again for the ideas/input.
