Folate and folic acid are forms of a water-soluble B vitamin. Folate occurs naturally in food, and folic acid is the synthetic form of this vitamin. Since 1998, folic acid has been added to cold cereals, flour, breads, pasta, bakery items, cookies, and crackers, as required by federal law.
The amount of time it takes to get in shape for a marathon differs depending on how fit you are currently. You should be able to run at least 15 to 25 miles per week and have participated in one or more shorter races in the past.f you have been running long distance regularly, this time period provides you with a cushion to increase your pace and strength before the big event. Start out running anywhere between 15 and 25 miles per week, depending on your workout history, and gradually increase to 30 miles per week if you can handle it.
You will find that as you do more and more running, your body (and mind) will start to crave your runs. Once you have your running habit well set, then you can add in cross-training. Remember that Rome wasn't built in a day and no new habit is formed in one week. So the basic answer to the question how often should I run is three to four days a week with some cross-training thrown in, if possible, and at least one day a week of rest. And one last thing: remember to have some fun, even on those days when your run is on the tougher side.
