Trust me when I say what sounds good in the store may actually be a real negative on course.
I'll ditto this and add that the reverse can be true, too... I never considered gels because they were described as being similar in consistency and taste to cake frosting - and I HATE cake frosting! So I avoided all gels for a couple years, but as my distance got longer and I needed to carry more calories, the weight and bulk of alternatives got real old, so I finally tried a chocolate Clif Shot... and lo and behold, I LOVED it! I would truly never eat those things outside of running, but my palate and system dig them on the run. Who'd have thunk it?!
But what did I use before finding gels? I did really well on Fig Newtons and pretzels. Really, really well. The downside to them, though, was that it's hot and humid here in FL and newtons do not hold up well in a waist pouch under those conditions. I still like pretzels and will bring a tiny bag with a few to change things up during a long run.
As to how much to fuel and how often, I have chronic and reactive hypoglycemia - my blood sugar level is very low to start, and drops to dangerous levels with exercise. In daily life, I must fuel properly throughout the day to avoid a crash, and it's especially critical when running. I aim for around 100 cals every 45 minutes and keep an extra gel on me for the inevitable crash 10-15 mins after I stop running, just in case I can't get other food that quickly. I realize I'm not average in that regard, but it's something folks need to figure out, whether through medical testing/advice or experimentation.
Question - what do people like to use for sodium replacement?
I'm probably not the average runner in that I run in extreme heat more than half the year, but my doc's advice after a couple of scary incidents was to up my salt intake ALL of the time during the hot months, not just during a run. So I avoid low-sodium foods, add a little sea salt to dishes I prepare, drink Gatorade or Nuun before, during and after runs. No more tunnel vision, sudden stop of sweat, heart palpitations, etc. doing that!
