oh boy..
OK, well as you know, those are two pairs of girls making four total. I know the first two are from B to B 2009. I know this because I attended and watched them arrive, disrobe and prance around naked the whole day. If you want proof, visit my Flickr stream here:

hopefully, that link will take you directly to my 2009 gallery. I also have another 50 or so unpublished pics of those two.
NOw the other two are from B to B 2009 also. In fact, I have at least one pic of them in the same gallery linked to above.
Then there is another Flickr user who took some of the pics posted above but has more. I'm not sure of his name, but since those first two girls were so popular in 2009, searching Flickr on "Bay to Breakers" and then clicking on "most interesting" should put them near the top of the pile.
I sincerely hope this helps you in your quest
