mornings def work for me , like a lot of mums its difficult to get out after work due to kids/meals/baths etc. my friend and i ran all through winter setting out as soon as it was light enough to see our feet in front of us! like someone else mentioned, non-runners dont understand why you would want to get up on a freezing morning on a weekend to run at 7am, but i tthink its great.
i dont run with an ipod as i love the peace , the wildlife waking up i get to see, and being part of that group of people whom you nod and gasp 'hello' to when you are out at that bizarre time of day. sometimes i do run midday time if its only time avaliable to me , but its really not the same. 
join the morning gang everybody-its another world!!
