All open source and no play makes Jack a dull committer...
For a few years now, we've been putting together fun things to do for recreation in the AC cities.
This year, the Marriott has done a fair amount of the work for us up front, so check out http://oaklandcvb.com/visiting_sports_recreation.cfm
As always, there are a fair number of runners at AC. If you are interested in running, add your name, contact email, distance, and preferred times below:
Grant Ingersoll, firstname.lastname@example.org, 3-6 miles, morning (7am?)
Jean-Frederic Clere, email@example.com, 6-8kms, morning (7am?)
Rainer Jung, firstname.lastname@example.org, 5-8 km, before breakfast (~ 7am?)
Yegor Kozlov, email@example.com, 5-10 km, morning (7am)
We meet at the lobby at 7am and run to Lake Merritt, around it and back to the hotel (~7kms / 50 minutes run)
Obviously, there is a lot to be had outdoors in CA, but there is also a gym that isn't too far away: Berkeley Iron Works http://www.touchstoneclimbing.com/ (http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=Oakland+rock+climbing+gym&sll=37.964907,-122.053127&sspn=0.406008,0.741577&gl=us&ie=UTF8&hq=rock+climbing+gym&hnear=Oakland,+CA&ll=37.808869,-122.272596&spn=0.024582,0.046349&z=15&iwloc=B)
Tilden Park in Berkeley offers some good outdoor bouldering. See http://maps.google.com/maps/place?oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&q=tilden+park+berkeley+ca&fb=1&gl=us&hq=Tilden+Park&hnear=Tilden+Park&cid=11807705394983064033
Again, probably better cycling in the surrounding area than anywhere near the hotel, but maybe some locals can add their info.
Oakland Ice http://www.oaklandice.com/index2.html, they have an air hockey table. Hours vary.
Singing Piano Bar - Rod Dibble is an Oakland staple. You can sing standards with him at The Alley, which is a swift taxi ride away from downtown.
Grand Lake Theater - http://www.renaissancerialto.com/ Old school theater, beautiful building.
