3km out and back

Today did a 3km out and back. These out and backs I am not very keen on to be honest because it is so hard to judge your pace after running the same distance slow. Also quite tired this morning after not much sleep. Started off well, really nice weather this morning so that was good. Did the easy 3km in 15:10. Then came the hard 3km. I was running on a very hilly course again today. There isn't really anywhere flat around here which is good for training, but everything hurts much more. First km is always the worst and nothing changed today as I went through in 3:45. Tried to push hard this next k and managed 3:17. The end of the last km was up an enormous hill and I did it in 3:30. 10:37 the final time so not too bad. 6km in all.
