Back to the gym last night for another date with the treadmill (it topped 100 degrees here yesterday, so, for now, I need to run indoors). Didn't do too well. I had gotten a sample gel and decided to try it. Downed the gel and a few gulps of water right before taking off. Launched into a 10 min. mile pace and started feeling nauseous from the get-go. Varied my pace between 6mph and 6.6 mph and percent grade between 0 and 3 and lasted about 5.75 miles. At that point I just couldn't keep going - I had horrendous side-stitches, I started passing gas, and still felt like I was going to puke! So, I ramped down the speed and grade and walked another 1/2 mile or so and called it quits for the night. Bleh. I HAVE to up my mileage and I'm getting worried. At least now I know that gels are not going to work for me. Unfortunately, I haven't figured out anything (even plain water) that works for me while running - the only thing that works is an empty stomach, but that isn't going to cut it once I get much over an hour . . . Any suggestions?
