Skip trying to simply sweat off the pounds with saunas and sweat suits. For true, lasting weight loss, instead keep your focus on a consistent, balanced workout plan and a healthy diet with the right caloric deficit.
I'm thinking about training for a marathon. A marathon is 26.2 miles or 42 kilometers. Although some marathons differ in their terrain (some are very flat, some are extremely hilly) and degree of difficulty, the distance is always 26.2 miles. Races that are shorter or longer in distance have different names (such as 5K, 10K, half-marathon, or ultra-marathon).
The conversion of this distance into Imperial units is approximately -- not exactly -- 26.21876 miles, a distance that is commonly rounded to 26.2 mile.    The official length is 42.195 kilometres (26 miles and 385 yards)    It depends on the Marathon. (MORE)
