Personal opinion, don't get hang-up on gels - you can get by perfectly on what is on offer at the tables - but have a plan around how you will use it etc. (In fact, one can do Comrades on very few carbs if you have conditioned yourself in the preceding months.) BTW - Baby potatoes etc can actually be a plan, it is working for maybe thousands of runners
Use the marathons and ultra's leading up to the Comrades to experiment, test and refine your nutrition plan.
