I think I need to train myself to focus on certain things when I'm running and NOT how many metres I have left to go till I reach a certain km, not I will keep going till I reach a nice round figure, not when I get to 30 mins I'll cool down, not I WILL NOT cheat and not check the time or km until this song has finished (treadmill running here), etc. etc.! 
I'm so negative until the adrenaline gets going, usually 30 mins in, that I am ready to give up sometimes even after only five minutes! I don't though, but I hate the negative thought processes going round and round, because I just can't wait for it to end, even though when I do keep going of course I am chuffed and feel great. But it's like that every single time and I would like to change it.
I heard that Paula Radcliffe used to keep counting to 100 over and over...does anyone else do anything as monotonous? I need to hear what goes on in your heads to see if I can alter how I think when I run. Music is a big thing for me, and running to a track I really like can inspire me to go just that bit further but I'm stuck in a rut.
Please share!
