are we talking real fasted rides or early morning rides using the previous nights dinner.
Every sunday Im up at 5 either doing an hour (hi intensity – intervals) on the turbo or out for 3-4 hour ride (70 miles plus hilly ride – good for KOMs with few cars about!), i dont eat or drink anything beforehand (otherwise Id wake the kids up!), drink I use High 5 zero (no carbs) and usually have a cereal bar (9 bar) or two in my back pocket, but 9 times out of ten Itll still bethere when I get back… Never hit the wall or had problems.
Once im back however Ill have scrambled eggs, chorizo peppers mushrooms and a bowl sized mug of coffee.
