Calories for swimming?

How many calories are burned when swimming in 25 yd laps?

• I recently started swimming, 2 hours every day, in my local natatorium (pool). It's 25 yds across one way, and I want to get a good workout. I swim rather slowly at the moment, freestyle laps, I guess you could say. I've been to so many websites and every single one says something different. Fitday says 2 hours would only burn 1400 calories. Another fitness magazine said I'd be burning 2800 calories. Which is more accurate? Thanks!

  <revised> That changes things a bit. Wow, 65 pounds lost already. That's fantastic and keep up the GREAT work! At 365, one of the websites says 2400+ calories. But you know what? The 65 that you've already lost is what is important. Obviously something is working! Stay on your routine, get lots of support, take small steps and you'll reach your goal. Kudos to you! <original post> It's about 1100-1400. 2800 is way, way too high. Important factors include weight, and speed. I did a google search of "calories burned swimming" and checked the first three sites and they were all around 1400 for 2 hours of swimming. Some of them were only for 10 minutes, so I multiplied results by 12.
