I just lost 25 pounds in 10 days?

I’ve always loved working out (jogging, biking), but I’ve decided to train for a triathalon and really push myself (im 5′5..and just a bit pudgy..lol) . I’m 21, and about 11 days ago, was 128 pounds; I have been biking, swimming, and running for 12 hours a day, for so far 11 days. I got on the scale this afternoon, and now I weight 102 pounds?!? But, Is that even possible?? I’ve got on 3 different scales and they all say the same thing! I also got a calorie burner watch/heart strap thingy to see how many calories I burn while training..during 12 hours, I burn around 8000!! I’m eating like a HORSE, so, what’s the deal? How can I lose so much weight in such a short amount of time? (I think maybe some of it is water weight..but like I said, my clothes are so loose, that my pants are falling down to my ankles, so it can;t ALL be water weight..right?) …so confused

NICE. It sure is possible. Good job for achieving what most people can’t. And in 10 days; Wow! You must look really great! Keep up the good…Uh….Good job with…:( How can I not make myself sound like a teacher?…NICE.
