Interesting: according to my site stats, someone came to my blog via the search string “length of sf ballet program 1.” Good question!
The running time including intermission(s) for San Francisco Ballet programs can be found on their website on each program page. For example, Program 1’s total running time is 2 hours 25 minutes with two intermissions, shown here. If you want a further time breakdown of each program, check out their press kits as they become available.
