This is an update to my post in April. For the Coastal Delaware Marathon, I used Spring gels every 3 miles with a Clif Bloc chew as an alternate. What I noticed recently is that these gels provide significantly less carbs than the Huma gels (17g vs. 21g) and less sodium (60mg vs 250mg). This might explain some of issues that I saw in the race (bonking around mile 20 and cramping at mile 24). I am targeting 60g of carbs and 750mg of electrolytes an hour. To get there, I am now planning on using/executing the following: taking a gel, electrolyte capsule and BCAA capsule 15 minutes before start of run (to pre-load energy processing prior to the run) taking a gel every 20 minutes rotating through carb boom!, huma, and spring gel every hour (one of each, and 1-2 will be caffine) adding 1-2 salt capsules from gu every hour (140mg per capsule) adding a BCAA capsule from gu every hour (will have to see if this helps in long runs) I hav...
