Utah Running: First off, I wanted to thank you for taking the time to do this interview. We are beyond excited to hear from you. This interview is going to be a part of UtahRunning.com’s Summer Edition Run Utah Magazine. The theme of this magazine is “The Complete Runner: Training Your Body and Mind for Total Running Fitness”. After writing the outline for the magazine and deciding I wanted to write a mind over body article you were the first runner that came to mind. I believe lots of people have this perspective of you being the epitome of being mentally strong in competition and training.

The first instance that comes to mind of your mental strength is the Nike Sub 2-hour attempt. Attempting something that for years had been this elusive goal for the entire marathoning community yet had been seen as an almost impossible task. You went in with so much confidence and really changed the worlds perspective on if a sub-2 hour marathon was even possible. Can you talk to us a little bit about your approach to this event? Did you approach this event any different than you do a typical world marathon major? If so can you elaborate on some of those differences?

 

Eliud Kipchoge: Thank you once again, remember to every human being it was impossible, I approached differently in that, it took all my time for seven good months, I changed my thoughts and tell my conscience that, I am going through, be it in any circumstance.

For a normal marathon, it’s just running to win, but for breaking 2, it was about running against the unthinkable, that’s a big difference.

Utah Running: During the Nike Sub 2-hour attempt, we all watched in amazement as you came within seconds of making a sub 2 hour marathon a reality.  Could you describe the experience from your perspective? What were some of your thoughts throughout the experience and after you finished and the results had settled in?

Why is Overstriding Going to Make Me More Injury Prone?

By: Preston Johnson

Whenever you find yourself with a group of runners it isn’t uncommon to hear the topic of heel striking (initial contact with the ground while running is with the heel of the foot) and forefoot striking (initial contact with the ground while running is with the forefoot) brought up. While neither of these styles are necessarily bad, studies have shown that those that over-stride and heel strike excessively have a much higher rate of developing a moderate or severe injury and it is shown to be less efficient and effective when trying to run fast. We want to dive into those concepts a little bit and talk about why it has those effects on your running and talk about how you can fix it.

To explain the effects of overstriding I am going to use some graphs generated from a ground reaction force plate (measures the amount of force on the plate over a period of time). Thanks to Newton’s 3rd Law we know that for every action there is an equal and opposite reaction. So for the amount of force that a runner puts on the plate, as he runs over it, the same amount of force is exerted back on his leg. These forces exerted by the ground are common causes of many running injuries. Let’s compare the reaction forces between an overstriding, excessive-heel striker and a forefoot striker.

 

The major difference shown in the images above is fairly evident. We are focusing on the extra spike in the force of the heel strike graph. This extra spike of force exerted through your leg is not absorbed very well when overstriding. When you are overstriding, your heel strikes the ground out in front of you with your leg a lot straighter than it would be if you were landing just in front of your center of gravity with your ankle bone directly underneath your knee (the optimal place to land). The straighter leg will decrease the amount of force that is absorbed through your muscles and joints and instead the force is being absorbed through your bone, which is far less elastic than your muscles and ligaments in your joints. This increases your susceptibility to stress fractures and stress reactions. Another important factor is the rate at which the force increases. Notice that in the heel strike graph the rate at which the force increases is very sudden as opposed to the forefoot strike graph which has a more gradual increase. This sudden increase creates a much higher impulse force than a gradual increase does. This impulse force in heel strikers has been seen up to 7x the force of someone who lands just in front of their center of gravity.

We mentioned previously that overstriding also effects your overall speed. In the image on the left notice the angle at which your foot hits the ground when overstriding. Thinking again about Newton’s 3rd law (every action has an equal and opposite reaction) imagine the force
from hitting the ground with your heel, when you’re overstriding, going in the opposite direction. This force is represented by the red arrow. Notice that the red arrow is pointing backwards. Essentially this force is acting as a break and slowing you down with every stride you take. Upon toe off you are required to exert more force to maintain the same pace due to the breaking effect of the opposing force.

So, this information is interesting to learn about, but it isn’t beneficial to you unless you learn how to fix the issues it presents. Focusing on landing on your forefoot or landing in a certain spot when your running is not the right way to go about fixing this, it can become very monotonous and will easily be forgotten as you continue running. Your body naturally runs in the most efficient way it can, but it is not necessarily the most efficient way for a human to run. If you find yourself overstriding and want to change it, focus on Increasing your running cadence, your ankle bone being directly beneath your knee when you land, landing just in front of your center of gravity, and building towards a cadence of 180 steps a minute. Increasing the strength of your Hamstrings and Gluteus muscles is important when increasing your cadence and shortening your stride. Doing squats and hamstring curls every other day is an effective way to improve that strength. As you continue to build strength spend some time on your run listening to a metronome (boring, I know, but its beneficial) set to a cadence that is 5% faster than your current cadence ((Current Cadence x .05) + Current Cadence). Focus on matching each step to the beat of the metronome. As this begins to feel natural over several runs, continue to progress the metronome by 5%.

Is Static Stretching Before Your Run Hurting Your Workout Performance?

By: Preston Johnson

A widely debated topic in the running world is whether or not stretching before your run is hurting your performance? We have been taught since elementary school that we should stretch as part of your warm up, but a study in Brazil, among others, may say otherwise.

The study was focusing on the effects of static stretching on your muscles output of power and strength. Along with previous studies pointing to a dampening effect on your strength and power, there has also been more conflicting studies pointing to the fact that it may decrease your running economy.

First, we want to clarify that this is not saying that stretching doesn’t have a place in the running world, because it surely does. Stretching is still highly encouraged post-run to help any sore or tight muscles to aid in the recovery process. We are solely going to focus on the debate of whether or not it is essential to stretch before a run.

This study took eleven recreational runners and put them through several tests, including a 3-km time trial. This test was done twice once without stretching and a second time with static stretching prior to taking the test. The stretching consisted of seven lower-body stretches performed three times each for thirty seconds.

Speed was measured every one-hundred meters in both the stretching and non-stretching trials as well as the perceived exertion every four-hundred meters. The graphs below show the results of the trials.  Keep in mind that RPE on the graph on the right stands for “Rate of Perceived Exertion”.

The findings showed that there was a significant difference in perceived exertion and the actual pace being run when comparing the control time trial and the static stretching time trial. The pace was significantly higher with a lower perceived exertion level for the group that didn’t do any static stretching prior to the time trial. However, there was only a measured significant difference in the first 100 meters. The running economy of each runner was not effected by static stretching, but the stride duration was increased. Ultimately, the finishing time between the two groups was unchanged.

Race Day Preparation

Pre-Race Preparation

No matter how hard you train, the days leading up to a race can make or break your performance. There is no one proven way to prepare for a race or big workout, so keep in mind that some, all, or none of these strategies may be beneficial to you. The following are some of the most successful approaches to race day.

Tapering: In the days leading up to a race, cut back on the length and intensity of your run. For some, it is mentally difficult to ease up during runs leading up to a race for the fear of “losing fitness”, but keep in mind that a few days out from a race you are already as fit as you’re going be for that race. You don’t have anything to gain from running faster or farther, but you have a lot to lose. Enjoy some easy runs and focus on the race ahead.

Nutrition: This is probably the hardest aspect of race day preparation to master. It is very individualistic, so tweaking the following ideas to fit what you know your stomach can handle while running is encouraged. Your mindset towards food as a runner should be something resembling “calories equal energy”. This doesn’t mean you should go eat a dozen donuts, however, not all calories are created equal. As you become accustomed to racing you will start to learn how much food you need to be properly fueled for the upcoming race. When fueling for a race, the majority of your diet should be complex carbohydrates (roughly 55-65% of your caloric intake). Common meals for runners to eat the night before the race that aren’t too hard on the stomach that also includes high amounts of complex carbohydrates are baked potatoes, rice, and pasta (ideally with a red sauce). What you should eat on race day is very dependent on when your race time is. We advise that you shouldn’t try anything new on race day experiment with what works for you on days when you workout, not on race days when you have more at stake. Aside from what to eat, don’t eat any meals too close to your race. If you haven’t made this mistake yet you are either very lucky or know your stuff, but if you have made the mistake of eating too close to a race, you will never forget it. As a guideline, most runners need at least three hours between their last small meal and their race, and many need even longer. Last tip for nutrition: make sure you stay hydrated! No matter what the temperature is going to be on race day, being hydrated helps your body run more efficiently. It impacts a lot more than just temperature regulation, it also impacts your bodies ability to deliver oxygen to your muscles, among other things.

Six Tips to Losing Weight

by: Meaghan Fors

There is a lot of different and conflicting information on the web when it comes to dieting. Almost everyone has a brother, mother, aunt, or friend-of-a-friend who tried a miracle diet, and it “helped them lose 50 lbs”! While most of the diets we hear about sound sensational, how do you know if it will work for you? How do you know if it’s even safe? We’ve done some research on the subject, and we’re here to share with you what we’ve learned!

  1.      What worked for your brother, mother, aunt, or friend-of-a-friend might not work for you.

 

And that’s okay! The more that studies are being conducted on weight-loss and dieting, the more scientists are finding that different bodies respond to diets differently. Weight loss, and the process of losing weight, is very individualistic. Depending on your genes and cellular make-up, your body may respond better to one diet over another. What worked wonders for someone else might result in you ending up the same weight or even gaining weight. It’s okay to have trial and error periods where you figure out what works best for you and your body.

 

  1.      Be realistic about cutting calories.

 

You are far more likely to succeed if you reduce your calories slowly and consistently. The best way to cut calories is to track what you eat for a week and find your average daily caloric intake. Then, reduce your caloric intake (what you eat) everyday by 10-15%. For example, if you eat 2,000 calories a day on average, reduce your calories by 200-300. If you eat 1700 calories, reduce your daily intake by 170-250. Your weight loss results will be slow and steady with this method, but you won’t run the risk of starving yourself and rebounding/binging when your body needs more nutrients. Generally losing 1-2 lbs a week is a good goal. Remember that one lb of weight loss is equivalent to a net loss of 3,500 calories.
