@pleiades Oh ok. I don’t eat anything in the morning before a run. If anything drink some water.
However for a PT test or for little extra kick, I sometimes take a bit of organic energy shot or a drink called spark. It has vitamins and amino acids, with caffeine few other things. Nothing too crazy. I always put like half a scoop which is 60mg of caffeine. Just enough for boost yet not to the point where I am spazing out.
Other than that, I just am sure to drink plenty of water throughout everyday and morning of I will drink some. Being hydrated and not just chugging gallons of water day before.
I’d say you have to experiment. For me I push myself hard on most runs as I am going for time and to improve. Throwing up is very likely for me. Not to mention the burps, possible stomach/cramp and what not. Ugh!
But that also depends on how long I wait between eating and a run. Thinking like 2–3 hours and I am ok. Depending on the meal. That’s just my body.
PS Since changing my overall diet and doing better with water intake. I find I hardly use the energy mix or organic shots in the morning. I have however did some experimenting with L-Arginine with L-Citrulline and I think it helped to a degree. Again though just personal experience and experimenting. By no means am I advocating, however do some of your own research! It can be enlightening! ;)
