I'm hoping someone might be able to help me. I've been running since August last year but I've only been doing fairly short distances (around 2 or 3 mile runs). I work full time 9-5.30 and my commute is about an hour so I can only train in the evenings on weekdays and at weekends. Overall my training has been going well and I enjoy my runs, I try and get out for at least 2 runs a week as well as doing a Spinning class once a week (half an hour) and some weight training in the gym.
My problem is that I am wanting to do a 10k at the end of March, and it starts at 10am. Now I thought because I am progressing well with my runs (evenings at about 6.30/7pm + weekends at about 3pm) I would be fine to do this 10k. However I went out for a morning run (2.5 miles so nothing different to my normal evening routes) around 10am when I had a light breakfast (cereal and one slice wholewheat toast) and I found it unbearably difficult! I tried again the next day (thinking the day before was a one off) and again, it was horrible and I found myself walking quite a lot, something which I have not had to do since 2009!
So my question is why am I finding it so hard to run in the mornings? And is there anything I can do to improve this situation? I was wondering if it was lack of food seen as my body is used to running in the evening when I have had breakfast and lunch, plus fruit (I dont really snack apart from an apple late afternoon)? Or is it simply a case of more practice in the mornings to get my body used to it? It is a problem because I cannot run weekday mornings so I would only be able to go out Sat + Sun mornings, something which I admit does not really appeal to me seen as I like to enjoy my weekends!
Let me know your thoughts or if you have any advice/tips for me!
