I have several times made a siyum on Tamid, either because I missed the morning minyan, or because I had no minyan available. (One year I was on a plane, and another year I was in a place with only one other Jew.) It takes me about an hour or a little longer to go through it (just the text, no Rashi).
But one year I was unable to leave my home or to learn Torah until chatzos, and faced the prospect of having to fast until an hour after chatzos. Fortunately someone was found to come and make a siyum
