On weekends, when I assume most people will be going to the city, the train ride is exactly an hour. Factor in the 10-15 minute bike ride to the station and 10 minutes waiting at the station (you’ll be there that early because if you’re late on a weekend you have to wait 1 hour) and it’s almost at an hour and a half. Then the train station is about a mile south of all the action (except AT&T Park) so add a 20 minute walk or 5 minute cab ride. </p>
<p>After all this, 1.3 hours is a conservative estimate.</p>
