For drink mix I stopped at a GNC on the way to the race and told them what I was up to. They gave me some powder and said to mix with water and drink just a bit before the start. I did and I think it helped a lot. I also had one bladder of gatoraid. I don't remember what the powder stuff was called, but I think they said it was mainly used by marathoners. I just drank water during the race because I didn't have a pit crew and snagged water from baja pits. I think a few gatoraid refills and maybe one more hit of that powder stuff half way though would have helped a lot.
A decade ago I used cytomax and it was good stuff.
buryurfear14, I live in DC and managed it. Drive out, race, drive home. Its a hassle, but do-able. If you hire bajabound you can even fly out.
