Thanks for all of your thoughts guys!
I know I'm not lacking in motivation - I would say I feel the same way about running in the morning as I do in the evenings so I dont think it is that. I definitely cant run in the morning during the week otherwise I would be getting about 5 hours sleep and that is no good. The problem is work - I have an hour commute to and from work, so I leave the house at 8am, and being a girl I take about an hour to get ready so I'm up at 7. So to then think about going for a run, I'd need to be out of the house at 6.15 ish which is just unrealistic for me to be getting up at that time. This is mostly because I'm not back home until 7 or 8pm, so once I have had my evening meal and done all the bits I need to do I'm never in bed before 11pm or 12pm. I'm pushing for a promotion at work so there is not a lot I can do about my hours at the moment, I just cant seem to leave the office before 6pm at the moment!
So it only really applies to running in the morning at weekends - I tried this for the first time last weekend and I cant believe how much I struggled. It wasnt a "cant be bothered" sort of feeling, it was more my legs were like lead and painful to move, I felt sick the entire way around and I was breathing hard right from the start. I cant understand why I felt like this in the morning over a distance I am used to running, whereas when I run this distance at the same speed in the evening I feel find and enjoy it? It really took me by surprise how I felt last weekend - it was such a strong physical reaction and I have not felt that bad whilst running since I started back in Augut 2009! Hence why I thought it was just a weird one-off the first time, so I tried again Sunday morning and felt the exact same way.
I was just hoping there would be an explanation, or at least some tips on how to overcome it! But maye I will just have to grin and bear it, and hope the adrenaline on the day gets me through!
