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).
5k race = 3.1 miles. Most beginner runners will take an average time to finish a 5k race of 30 - 40 minutes. 10k race = 6.2 miles. The typical time it takes to do a 10k race is 1 - 1 1/2 hours. Half marathon = 13.1 miles, 21.7 kilometres. A respectable time it takes to do a half marathon is 2 - 2 1/2 hours. Marathon = 26.2 miles, 41.2 kilometres. The average time it takes runners to do a marathon is between 4 - 5 hours. 5k runs have turned in to being a very popular way for charities to increase both funds and awareness of their particular causes.
