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).
Gumps-for someone like me, pretty much the only marathon that would carry significance for my friends and family would be London. Sounds carp because they know that 26.2 miles is 26.2 miles no matter where it's run-but the only marathon that matters to them is this one, which is why I'm pretty desperate to do it.
