Porridge, of course!
On my morning long runs, my pre-run meal is eaten at about 6pm the previous day. Not eating first thing might help your training to more efficiently burn fat on your ultra training. Your pre-run snack will just get your carb burners fired up. But if you must .. Porridge
I loved the cider suggestion, too, as I fail to believe the cooking time is enough to evaporate the alcohol. Start the day as you mean to go on
Pre-run I'll just have a banana or white toast with honey. I do shorter runs on fresh air, but Also-ran is tougher than me!
Mille feuille v gel is no contest. Don't blame you!
I don't tend to eat first unless the run is over 15 miles, but I now think I am going to have a pint of cider and a pretty pastry and see what happens.
