I'm doing the 5k programme using a different app on my iphone (it's called 5k Runner) and just did week 4 day 2 earlier today. This involved doing my first 5 minute non-stop run.
I just about managed the first 5 minute run but had to stop half way through the second as I just couldn't manage it.
Has anyone else noticed a big difference in your run depending on the time of day or what you have been doing beforehand? I find runs much easier in the evenings when I get home from work. I suspect this is because my body has had all day to warm up. I usually change into my running gear as soon as I get home so I'm not tempted to just veg out. However, at the weekend I will have just gone from my bed to the sofa!
Its a shame as daytime running means I can actually see where I'm running and can run round a local park which is not lit up at night, but I find it so much harder! Maybe I should start doing a much longer warm up?
