I never take water on an outside run under 1 hour but sip away when on the treadmill - for any distance - probably because 'it's there'. I did use a hotel gym the other day and the water cooler was empty, meaning I couldn't fill my bottle and managed fine without a drink, even though I had just got up and had not drunk anything for 9 hours.
Try leaving your bottle in the changing room! You'll be fine.
