In reply to lizard-16-07:
Probably quite personal, but the formula that worked for me was:
- Do my long runs early in the morning
- Eat well the night before
- Avoid wholewheat/veg etc - lots of meat/dairy and little carb worked for me, but see different experiences above!
- Have a good strong coffee in the morning but no breakfast
- Give Paula a thorough workout before leaving the house
It takes a bit of getting used to to run without brekky. Often I would feel queezy as if low on blood sugar when starting, but my performance (and science) suggested that, in reality, the glycogen in my muscles/liver etc were well topped up by generally eating well during the week and getting a good feed the previous night.
I also found that taking on electrolyte supplements helped a bit; just drinking water would have Paula jostling on my shoulder pretty quickly, particularly on hot days.
Good luck.
