Does anybody recomend any suplements to help with long distance runnin? GNC and Vitamin shop where recomending NO2 Black and this other stuff called VO2 max. I am already taking vitamins. Has anybody tried any of this other stuff or is it better just to eat right and drink lots of water?
Personally I don't use them or recommend them. It's hard to tell, or even find out, exactly what's in them. Some of them contain substances that are banned by USATF and other race sanctioning bodies. Even the pros often don't know. An example: http://jamaica-gleaner.com/gleaner/20140109/sports/sports1.html. Eat a good diet, and stay hydrated.
I neither use them or recommend them; hydration and a good diet is all your body needs.
Fat old man PRs:
This may or may not count to some people but I've recently started taking GNC's Women's Ultra Mega Active Multivitamin. Never tried this kind before but I've recently (just this year) increased my average mileage from 6 - 12 miles a week to 20 - 35 miles a week. I have taken their Women's Hair, Skin, and Nails formula and it definitly works!
Other than that I am super skeptical about supplements. I've read too many scientific reviews that say they are a waste of money and they don't work (in fact in some cases they can end up hurting). And you'll notice that people who swear by a particular supplement don't really need it if they have good fitness program and are eating clean. I think it's a placebo effect for these particular people. But hey! Whatever works for them. I prefer to save my money. Some supplements are just ridiculously EXPENSIVE!
I never recommend it. If you're looking for a general rule of thumb for nutrition consumption during your runs: You should take in 4 to 6 ounces of fluid every 20 minutes during your runs. If you are running faster than 8-minute miles should drink 6 to 8 ounces every 20 minutes. During longer workouts (90 minutes or more), some of your fluid intake should include a sports drink to replace lost sodium and other minerals. The carbohydrates and electrolytes in the sports drink also help you absorb the fluids faster. This is enough for you.
