I just finished a 5.752km run that lasted about 0hh:27mm:2ss !
I wanted to do a longer run but the weather conditions weren't good enough. It's not easy to run with snow coming in your face. So I just did a bit less than 6 km. I wanted to be slow but I accelerated during the run certainly because I wanted to go home.
I also experienced a strange thing with my shoes. I think this is the first time I run in the water with my Nike Pegasus 35 and it is not good at all. After not even 2 km, my right shoe was like a sponge at each step. I don't now if it's normal or not but this is the first time I experience that with any shoes. This is also my first pair of Nike so I don't know if it's frequent with this brand. If you are aware of this problem, let me know!
