Nutrition on the road - What, How and Why?

That might help a little bit but you should really sort out your on-bike feeding.

Set a time alarm on your Garmin to beep every time you should be eating something or do something else to make eating/sipping a drink a habit.

From the Dr Hutch book (for me this qualifies as research) I'd settled upon trying to get four "units" in per hour, which could be half a bottle of water with SIS in it, a gel or a solid bar.

Probably overdoing it though, and I struggle to actually (as you've spotted) remember to eat that in time.
