Is it okay to go directly to 200 kilometers by releasing pigeons from 50 kilometers? Is the return rate high?

It depends on the quality of your pigeons. Jumping directly from 50 kilometers to 200 kilometers is a bit big. If the weather is not very good, I hope you are lucky. If you have the ability, you can come back whether you are trained or not. If you don't have this ability, it's useless to train again. The training distance and sequence are: 25, 50, 50, 90, 100, 100, 120, 150, 200 km, 100 km twice a week./kloc
