Unless you're wiling to go *very* slowly, there's no good way to avoid eating carbohydrates during an ironman. To a zeroth order, the person who can burn the most calories per kg body weight will win, which means using every possible mechanism our body has in place. :) Hope the run went well and your training continues to improve.
I did the Dallas Marathon yesterday. It was unseasonably hot and humid. I ran a 4:08 which was a little disappointing but for my first open Marathon, I probably set my expectations too high. I maintained a LCHF diet through the last three weeks of training. I did, however, consume 6 gels during the race (miles 1, 5, 9, 13, 17 and 21). My cardio was fine. My nutrition seemed fine (I didn't bonk) but my legs were complaining the last 5 miles and especially the last two. I also had self imposed problems with my 910XT which complicated my pacing. I started experimenting with the LCHF diet too late in the training cycle to know how long and how fast I could go in training on just fat and stored glycogen (thus all the gels). Perhaps I can get a better handle on those factors as I switch to training for the Lonestar 70.3. It may well be that I run so damn slow that I don't burn much glucose. :-)
What I did learn is that 26 miles is a long way to run.
