Reego,
Water was free when I did C2C back in May, I just filled up from a spigot at the ranger station. Or maybe it was a drinking fountain I can't remember. I didn't catch anything so the water must have been ok. I was in Long Valley at about 6:30am so no one was around to ask.
As for running up Baldy, I'm not planning that, I'm only planning a possible hike to test the leg (and to get in at least some hill work if I try to get to Skyline Friday, the 17th). I've not run up Baldy but considered the race on Labor Day before deciding against it. I don't run enough hills to be able to do that comfortably. I hike up hills faster than I run up them.
