First marathon fueling/hydration — am I doing enough?
Hi everyone! I’m training for my first marathon and have been training for about 10 months. I’m currently running my long runs at around a 13:00–13:30/mile pace, and I’m trying to figure out whether my fueling and hydration strategy needs some adjustment.
During long runs, I currently take two SaltStick chewable tablets along with a Huma or Honey Stinger gel every 30 minutes. I also take sips of sugar-free Liquid I.V. about every two miles.
Before my long runs (12+mi), I usually drink about 1 liter of coconut water the day before and make sure I’m eating plenty of carbohydrates.
However, on long runs (12+mi) I sometimes reach a point where I develop a nauseous, tingling, lightheaded sensation. It can take quite a while of walking before I feel normal again.
**I’m wondering if this sounds like a fueling issue, hydration/electrolyte issue, or possibly something else. Is this what hitting the wall feels like?**
**Is what I’m currently taking during the run sufficient for someone running at my pace, or should I be increasing/changing my carbs, fluids, or electrolytes?**
For those of you who have run marathons at a similar pace, what fueling/hydration strategy worked for you? I’d especially appreciate advice on how to prevent that lightheaded/nauseous feeling during the final miles of a long run.
Thanks!
