I had the one packet of Gu last time, and I bonked BIG TIME. I could barely walk up the stairs to buy something to eat. This time I tried two packets of Gu, and it upset my tummy.

Keep in mind I burn 500-550 calories when I jog because I'm a big girl. I'm not sure if the standard 1-hour formula applies.

I think banana is next on the list -- that's a good idea. I'd love to try a small slice of banana bread sometime, but I'm out of my gluten-free special flours and can't get more until at least next weekend.

In the past I've pretty much been able to eat whatever on the bike, so this is a bit of new territory. I can't ever eat right before swimming, though, or I do get sick, but I've never bonked while swimming.
