If I don't try and warm up I normally get problems after 30 mins, if I do the 5 min reasonable speed walk first I have been known to last a lot longer. When I was more active the entire 5 mins was less neccesary, but that was when I was hitting 20-25k a week no problem rather that struggling with 15.
