I've never, ever had a gel. It sounds disgusting. Ham sarnie, flap jack or a banana for me. I have a big bowl of porridge before I go out and that does me. If I really feel the need for a big lunch (rare) then I can always stop at a cafe for some
cake thing more substantial
Reminds me of last summer. I went mountain-biking at Whinnlatter forest whith a mate and along the trail there was some gel wrappers. We had the discussion about the peckers that would need gels at a mountain bike trail park, when they are no more than five minutes away from a cafe at the bottom of the hill (not to mention the fact that they were arrogant enough to throw their litter on the floor!)
Gels have their place in an event where you need a big kick of energy in an easily consumable form (long TTs) even road racers manage to eat a sandwich and a can of coke while racing!
But it's your life, eat what
you want
