Taking an hour to relax and enjoy a wholesome home-packed lunchbox has become a thing of the past in today’s time-pressured McDonald’s society. Yet, that could be just the thing you are missing for that personal best .
The Kenyans have a very true saying – “An empty sack won’t stand up” . Translated – if you don’t eat well, you are going to suffer on your run.
There are two lunchtime mistakes we can make as runners which will have a big negative effect on our run.
The first is skipping lunch. When we do this, we simply just do not have enough energy to run at the fast pace we are asking of our body. If you had a good breakfast then the effect is less, you still however need to keep that blood sugar topped up during the day for optimal performance. With a long easy run, you can get away with not eating much in the hours before as the energy demands in both amount needed and how quickly it is needed are not as high. When going for that 5k PB, you are going to need a lot of energy and need it fast. This means that your body is going to relying primarily on glycogen stored in your liver and muscles. Glycogen is basically stored carbohydrate. So we need to ensure that our glycogen stores remain full by getting in enough carbohydrate throughout the day.
The second mistake is eating the wrong foods at lunch. These are foods that take long to digest, are gassy, cause acid reflux, could lead to nausea or an upset stomach or very sugary foods that can lead to blood sugar spikes (with accompanying dip on your run!). For example, red meat can take up to 7 hours to digest, so if you have a steak at lunchtime, you could still be digesting come time for your time trial. This will mean that the blood your muscles desperately need for running, is being diverted to your stomach. Common culprits for an upset stomach are: very spicy food, onions, dairy for some people, gassy vegetables and fruit, highly processed foods, caffeine for some. If you regularly get the “runners trots”, then avoiding all dairy and caffeine in the last 4-5 hours before your run can help.
That said – what are good lunchbox choices?
- Wholewheat sandwiches with e.g.egg, ham, cheese and tomato, chicken, salad
- Egg on toast
- Root vegetables – Sweet potato, potato, butternut, carrots
- Rice/couscous/pasta salads
- Bananas, Grapes
- Dried Fruit and nuts
- Low sugar fruit and nut bars
Timing of your lunch is also important:
Try to eat the bulk of your lunch 3-4 hours before your run. Then if necessary have a light snack eg. Honey on toast, banana, a few raisons, a little sweet potato an hour before.
If you have a long commute, then it is worth keeping light dry snacks in your car for topping up your fuel on your way to running that PB.
Very NB: Make sure you are staying hydrated during the day! If you drink a lot of coffee, then drink a glass of water with each cup to counteract the dehydration effect of the caffeine.
