People ask me how far it is to swim.

The thing is,  its not really a matter of distance, but time . 

When swimming against the tide one does not really go forward. One just swims on the spot, as if running on a treadmill. 

The question should be how long will it take to swim. How long will I last?

The longest swim so far is around 27 hours. 

I hope to be able to do it in 40
