I'm going to be in San Francisco later this week (6/19-20) and would like to do a long run (maybe 16 miles or thereabouts). I'm staying at the Westin Hotel, Market and 3rd. I would like some recommendations for a route and also any info on water availability -- I would prefer not to carry my own on travel if I can avoid it

Usually, I run down to the Embarcadero and the left towards the GGB. Then back. I'd like to go a lot further this time, maybe over the GGB or maybe around the park and back. But I'll vary the route if water is available along the way!

Thoughts?
