I am slightly cook book obsessed, as you can see, so I was delighted when Runner's World launched a cook book just before christmas, and even more delighted when someone bought it for me! Its quickly become one of my most used Christmas presents and been super helpful for fueling marathon training.
The book starts with a section on "how to eat like a runner" and talks about nutritional needs of runners for effective running and recovery. Its really well written without being over sciencey but packed with useful information.
It also helpfully labels each recipe with a variety of tags, low cal, fast, pre race, recovery, which is awesome!
Sections include: Breakfast, snacks and smoothies, salads, soups, pizza and tons of other things.
I think I found it most useful for baking snacks such as these banana oat energy bars and for finding healthy pasta recipes, as well as great quick and easy soups and stews. You can buy it here on Amazon.
