I am a female in my late 30s who is trying to race a fast (for me) half marathon this winter. I run 25-30 miles a week right now with my long run being 10 miles. Obviously this will increase before the half.
My question is how important is nutrition in terms of speed and performance? My diet is average at best. My weight is ok, I'm 5'8" and 125 lbs. If I switch to cleaner eating will it make a difference in my speed? Right now I eat an average American diet. Cereal for breakfast, sandwich for lunch, yogurt, and dinner is anything from burgers to chicken and rice to pizza. Not a lot of vegetables I'll be honest.
For health, extremely important if you want to be old and healthy some day. If you don't care what happens after 50 and it doesn't matter if you get a heart attack/stroke at age 60-80, then not that important. BUT with modern drugs you can also do miracles to your disease risks and come very close to the life expectancy of those people who are eating a very healthy diet.
For speed and performance as a young person it doesn't matter much. For speed and performance as an old person it matters: you won't have good performance with clogged arteries. Here too, you can compensate with drugs(not PEDs) a lot and keep your arteries clean for example.
