Do you know your body fat percentage Catrin? I find that to be a good tool to decide how much weight I can realistically lose for a particular event. If you're 128 and 20% BF losing 10 pounds of fat (because you don't want to lose your muscle you need that for your event!) would put you at 12%. Not realistic. But if you're at 25% losing 10 pounds of fat would drop you down to about 17% - not so unrealistic.
