I usually only run around 5 miles but I have been running longer distances more recently and completed a half marathon the other day.
I didn't feel too bad when I got home apart being drenched in sweat and a little lightheaded, so I took a couple of ORS tablets and instantly felt a lot better.
Would it be better to invest in a backpack if I start doing this regularly or would I be able to get away with running for two hours and no further?
Thanks all.
