The video sequences were shot in an around the SF Bay Area. Much of the riding was on Mt Tam (Marin) with some around Mt Diablo in the east Bay. The swim sequence was in the East Bay near Berkeley. The running is near Tennessee Valley in Marin. The footage was a part of an experimental project by Derek Weiss (www.pitonproductions.com) and reknown outdoor life photographer Martin Sundberg (www.martinsundberg.com). If you like that scene then check out HOW it was shot - with the remote helicopter used. Amazing stuff.
