Kim
Boudreau is the Ask an Expert Nutritionist for the Cape
Breton Fiddlers Run. She is a registered dietitian working
for the CBDHA.
Kim is a
runner herself. She enjoys running indoors; you will
usually find her running on the treadmill at the Y. When
Kim is outdoors, one of her favorite places to run is King’s
Road. This is a convenient place for her because she just
steps out her front door and is ready to go. She also
enjoys the scenery, the gardens, plants and trees and
especially the water. “I love running alongside our
beautiful ocean, and thankfully in Cape Breton, you’re never
too far away from that!”
We asked
Kim some questions and she was able to provide great
nutrition tips for runners.
1.
What
types of food should runners eat before a race?
Runners
should incorporate a healthy, well balanced diet all year
round. More specifically, meals should be rich in complex
carbohydrates (such as whole grains, fruits and vegetables)
and also provide adequate protein (such as chicken, fish,
eggs, milk, yogurt, soy). It is also essential to drink
plenty of fluids daily, whether training or not.
The last
meal before a race should contain mostly carbohydrates with
a small amount of low fat protein. If a meal is large, you
will need at least 3-4 hours for digestion. For pre-event
snacks, you generally need less than 2 hours.
More
specific dietary guidelines would depend on the runner
(gender, age, fitness level, weight and height) and the
distance training/running.
2.
What
types of food should runners eat after a race?
Right
after a race, runners need to replace their glycogen stores,
which is the fuel that our bodies use to run. A recovery
meal immediately after an event could be something as simple
as a piece of fruit, a glass of chocolate milk or a granola
bar. That should be consumed within 15-30 minutes
post-exercise when muscles are most receptive to
re-fueling.
Your
post-run meal should be similar to your pre-run meal, a
carbohydrate rich meal to replenish glycogen stores, with
adequate protein for optimal muscle recovery. Again, the
amounts of carbohydrate and protein would depend on the
runner. Someone who completed a 10K race will need less
calories, carbs and protein than someone completing a
marathon.
And of
course, you should always include fluids before, during and
after your runs.
3.
How do
runners keep hydrated during a race?
The most
important step to keeping hydrated during a race is to make
sure you are well-hydrated before a race. If you are
dehydrated before you start a run, you will have difficulty
making up for it during a run, which can affect your
performance. Drink plenty of fluids each day to maintain
fluid balance and adequate urine output.
Adult
fluid requirements are between 25-35 ml per kilogram of body
weight per day. For a 130 pound woman (60 kg), that’s a
minimum of
1500 –
2100 ml of fluid per day.
An
athlete requires even more fluid. Aim for an additional
400-600 ml of fluid 2-3 hours before exercise, 150-350 ml
about 15 minutes before and around 150-350 ml every 15-20
minutes during a run. Replace fluid losses you lost during
exercise.
If you
are running in the heat, you need even more. If you are
running for an hour or longer, you may benefit from a sports
drink such as Gatorade or Powerade. Monitor urine output
(dark, strong urine is a sign that you need more fluid).
Remember to test your fluid tolerance with training to see
how much your body can tolerate. Don’t try to start pushing
fluids the day of a race.
4.
Do you
have any other nutrition tips for runners?
One
important tip is to try incorporate meals and snacks during
training. Determine what meals and snacks make you feel the
best, what you digest the best, what sits well in your
stomach before a run. Do you like oatmeal plus a large
glass of milk the morning of your big race? Maybe you do
better with a fruit and whey protein shake. Can you drink 3
cups of fluid 2 hours before a race or does that make you
need to run to the bathroom during the event?
What
type of meal you eat, and sometimes more importantly, when
you eat it, can help or hinder your runs. Never try
anything new on race day. For example, if you want to
incorporate carbohydrate gels or drinks into your
half-marathon training, try them during training runs, not
your big race.
