I always felt it can knock back the immune system at times. I certainly felt I have had colds "re-appear" after running. Don't have any scientific evidence for it though.
Sorry gillma, I hadn't actually read the link. I have now, seems to make sense. Not sure I will be carb loading after a run though. I have high carb meals on gym days, if I had them on run days it would just be carbs everyday lol.
Thanks Ju-ju- . I had forgotten about Vit D - and might try Berrocca. Must keep the immune system healthy and not assume that running makes me automatically healthy in all areas! (Wish it did, though.)
