Or just carry the extra bottles (in jersey pockets, htfu), and avoid the chaos that is the feed zone.
Then you can just stay to the left and watch the carnage unfold! And there's no risk of missing a bottle or whatever.
At worst you'll have warm water but that's better than none.
HA! Yeah .. HTFU indeed.
For the sake of ease .. have you ever seen anyone rock the rear saddle holder? I dont see any USAC rules against it. I realize it will look super tri-dork-fred, but it also is a competitive advantage.
When you say you "...need more than just water in this event", are you talking about nutrition, electrolytes, or something else? If nutrition, just take whatever you normally eat on a long ride. If electrolytes, IIRC Powerbar gels have about the same sodium content as a bottle of sports drink. If something else, you need to clarify.
I don't know the course, but assuming the feeds are equidistant, they'd be around the 25, 50 and 75 mile points. A 20 mph average speed would put you at a feed zone every hour and 15 minutes or so. If it were me, I'd carry three bottles and skip the first feed zone except to dump an empty bottle, and then pick up a bottle at each of the remaining two. That would permit you to consume a bottle per hour.
FWIW, a bottle in your middle jersey pocket pretty much disappears until you need it. I live in the boonies, and usually carry three bottles on long training rides. If you don't like carrying bottles in your jersey pockets, take Matt's advice: HTFU.
Demain, on roule!
