Today I went on another ride that ended up being about 28 miles round trip with massive cross/head winds on the way out... I think we only averaged about 12mph in that direction. We flew on the way back in, though. At our turn around point I decided to give my front tire a little air as it seemed to have a slow leak and ended up snapping the core (never had that happen before...). Luckily, both the guys I was with had spare tubes.
