I've been increasing my mileage and am up to 18 miles. I've experimented with energy gels, gel shots and gatordade. My problem with the energy gels and shots is that I have to make a pit stop! Two weeks ago, when I ran 16 miles, I began using the energy shots about an hour into the run and then every 25-45 minutes after that. About mile 14 I started noticing the need to make a pit stop. By the time I got to mile 16, it was unbearable. I couldn't have gone further than 16 if I had wanted to. I did 18 this weekend,but had to split my run (12 miles in am, and 6 miles in pm). I plan to do 20 in two weeks and I don't want to have to cut it short due to nature calling. I wonder if I could just fuel with gatorade. Would this give me the carbs and energy I would need to make it all the way? My stomach doesn't react to gatorade the way it does the gels and shots. Would love any advice!!
