I can't speak for Liza as I don't know what she did specifically but I have seen some runners actually just hold their phone in their hand as they run. She also had a water bottle, so that would be two hands full, which would seem annoying to me, but who knows? I also wonder if those shorts have pockets though. It could be they have pockets that zip and it was in there or some athletic shorts that are baggier (these look a little loose, not skin tight like bike shorts) have a sort of built-in undershort underneath them that have pockets. Lastly, I know some runners put their phones in arm bands but I don't see one on her. MOO
