I had a 5 mile run last night. It was was of those runs that reminded you it has been just a couple of weeks since you ran a marathon. Feet feel like they weigh 30 pounds each, legs feel like iron poles. However there is nothing wrong with a run like that. I think it is good to treat a run like that as how you might feel in race. You don’t always feel up to it but you just need to press on.
