I’m training for amarathon and get annoyed by having to stop to urinate during my training runs. I drink a lot the day before, and I drink about 8 ounces 45 minutes before I start. I then have to pee at mile 2, then mile 5. The urine is a light color. I’m tempted to not drink anything…
The kidneys need about 45 to 90 minutes to process liquid; nerves might hasten the process! Try drinking earlier, void the excess, and then tank up again. For example, if have a long run on Sunday at 8:00 am. Drink well the day before (stopping by 7:00 p.m, so you don't wake up 5 times during the night to go to the bathroom), then in the morning, have a good drink by 6:00-6:30. That should give you time to get rid of the excess water.
Alternatively, if drink well the day before and are well hydrated, you could drink 8 to 12 ounces right before you start the run, so the water will be in your system and not in your kidneys.
Experiment and learn what works best for your body!
Yes! Despite popular belief, eating a fruit- or grain-based snack, such as an energy bar, banana, handful of pretzels, or an apple, just 5 minutes before a workout can boost your energy at the end of the session. Research also suggests that eating 15 minutes before you exercise is as effective for boosting your energy as eating an hour before.
Your body can digest food while you exercise. Your muscles get to use the food to enhance your workout, as long as you are exercising at a pace that you can maintain for more than half an hour. Most athletes train at a moderate pace, hence they can benefit from a pre-exercise energy booster. If you’ll be doing a sprint workout, you might want to eat an hour or two pre-exercise, so the food has time to empty from your stomach.
Your best bet is to experiment with different pre-exercise snacks, to determine when you can eat them without causing distress, and which ones settle best and help you perform at your best.
Having a drink of water right before exercise is also a smart idea, even if you will be exercising for less than an hour. Water is also helpful during exercise. Water can turn into sweat In only 10 minutes (in trained athletes). Ingested fluid moves rapidly, so don’t hesitate to keep drinking even towards the end of your workout.
