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).
Marathon Distance. All marathons are 26.2 miles (26 miles and 385 yards) or 42.195 kilometers. The difference between the various marathon courses comes in their terrain, rather than their distance, ranging from extremely fast, flat courses such as Chicago to more challenging, hilly courses such as Boston. The Boston Marathon is 26.2 miles long.
