i don't know if i heard this right but gouchers problem with taking down fluids was no surprise based on the announcers statement that the solution she was drinking was 1/2 diluted powerade (the announcer even gave the flavor!) with a gel. that is a lot of cho probably close to the upper limit for optimizing gastric emptying. hence her gastric problems aka like bob kempanian in 96.
based on the conditions hydration should have been stressed more than optimizing the cho intake.
