Day Breaker HM...from PB to PW, all in 12 weeks!

19th July: Day Breaker Half Marathon
Due to incessant rains over the past few weeks, I had been anxious over the days leading up to the event. Every few hours I would check the weather forecast for Sunday morning. I had been silently praying that the forecast of rain and high humidity would not come true. After all, this was going to be my last event before the Airtel Hyderabad Marathon (AHM) scheduled for next month and I was keen to get a good uninterrupted run before AHM. Well, part of the prayer did get answered – thankfully it did not rain, but the unanswered part (i.e. the part related to humidity) was about to offer me the toughest weather conditions that I have ever run in!

Just like in any other event, I was in my own zone prior to the race kick-off. I was warming up in a corner and silently hoping to improve my PB (personal best) timing of 97 minutes, which I had achieved about three months back at Nehru Park HM. Just then my coach Jatin Arora walked up to me and offered a coaching tip:  
Today is not the day for timings and records. It is very humid – don’t push very hard and focus more on completing the run safe and strong” – whispered Jatin softly in my ears. It was almost as if he had read my mind.
Yes Sir – I understand that. Today is not the day for timings and records” – I replied, without meaning a single word of it!

Shortly thereafter, the run started and I started chasing the target time of 97 minutes. The run seemed to have started well for me. I was not running very hard so that I had sufficient energy left for a strong finish. At the same time, I was not running slow either, lest it becomes difficult to catch-up towards the end. I seemed to be moving at just the right pace.
Out of habit, I kept glancing at my stop-watch at all major milestones:
  • 1 km – 4:30
  • 2 km – 8:52
  • 5 km – 22:49
  • 10 km – 46:38  
I made a quick mental calculation and realized that I was pacing well. With a mild negative split (which I usually manage), I would have been around 97 mins mark and with a little bit of luck probably a little under 97 minutes. What I didn’t realize was that it was the adrenalin rush of the event day which had me going well till that time, but that couldn’t have been sustained for another 11 km in that atrocious humidity.

By around 13 km mark, I was badly drenched with sweat. The effect of humidity had started showing up and it felt like the engine was running out of ammunition very fast. It was around that time that the wisdom of Jatin’s advice started dawning upon me. The spirit had started dropping, but somewhere I was still hopeful of completing strong.
By around 15 km mark, the hope had also started dropping and it felt like I would have to run really well from there on to not hit my PW timing (personal worst, if there is something like that)!

By around 17 km mark, I was so drenched with sweat that it felt like I had taken a shower. Each step gave a sensation as if the shoe had been soaked with water by landing in a water pit. By now, I knew I had to do something different to even complete the run. Amidst dropping spirit and dropping hopes, I decided to drop-off my T-shirt too. I realized that with the amount of sweat it had soaked, just taking it off and squeezing out the sweat would probably make me carry half a kg lesser.
Shortly thereafter, the run came to an end and I did manage to achieve my PW by clocking 1:49 beating my previous PW of 1:47. The time I took for the run was about 2 minutes slower than my previous slowest run and a good 12 minutes slower than my PB of 97 minutes. All in all it was a good humbling experience with some great learnings, the most important one being – follow your coach’s advice.
On the positive side of things - despite the atrocious weather, the euphoria and the enthusiasm at the finish line was there for all to see. For me, the highlights of the day were:

1.       Coach Ravinder Singh did it again!
Rain or no rain, humidity or no humidity, route permit or no route permit (remember Nehru Park HM instance), Coach has developed a knack of organizing great events one after another. Here again, observing the celebrations and sumptuous meal at the finish line was a grand experience. It is no wonder that on the same day Coach was honored by TomTom (Global leader in navigation, sports watches etc.) for his contributions in the field of running and promoting running as a way of life.

2.       All running groups rocked!
It was great to watch my fellow runners from Boot Camp Yellow (BCY) and other running groups running hard under testing weather conditions. Everyone was a winner and could hold his / her head high for taking on a challenging run head-on. And may I dare say, none more so than the youngest member of BCY group (Rahul) – who completed his first half-marathon yesterday at a young age of 14. I heard one of the fellow runners commenting - 5 km before 5 years, 10 km before 10 years and 21 km before 21 years are all great accomplishments and I couldn’t agree more.

I have to admit that before reaching home, I was feeling a bit embarrassed to share the result of my slowest half-marathon with my wife. She made the job easier by saying that in such an unforgiving weather even standing still for 1:49 is commendable, running for that long certainly is a huge achievement. I am not sure how true that is – given a choice, I would rather run for that duration than stand still. Nonetheless, it did help me overcome the disappointment of my slowest HM.

...So, What next?

Next month I am travelling to Hyderabad to participate in AHM. I have heard a lot of nasty stories about the difficult terrain and weather conditions at AHM. Personally, I would have wanted to achieve anything but my PW in the last event before going into AHM next month. However, that was not to be and the only next step from here on is to prepare stronger and harder. As I earnestly start preparing for the next event, I so much hope that I get to label my next blog in September as - AHM 2015...from PW to PB, all in 6 weeks!”

…but I know it’s easier hoped than accomplished!

Fuel your engine with right nutrients!


As a Mechanical Engineer, I was always fascinated by automobiles. I was intrigued by how a simple automobile engine converts chemical energy of fuel into motion. Now that running is my newfound passion, I cannot help draw parallels between running and automobiles. Fundamentally, the two are very similar – both machines draw upon the energy from a fuel and convert it into kinetic energy (i.e. motion). However, the choice of right fuel is far more nuanced in the case of human running. This blog explores some key aspects around the choice of right nutrients to ‘fuel’ an athlete’s body.

Recreational runners are often obsessed with the idea of enriching their diet with carbohydrates and for right reasons. Carbohydrates, after all are the energy giving food and are critical for runners, especially long-distance runners. However, this obsession with ‘carb-loading’ at times leads them to neglect other important nutrients. An efficient runner needs right amounts of all types of nutrients – proteins, carbohydrates, fats, vitamins, minerals and water. The right amount and source of these may vary by the training needs. In this blog, I explore (and I deliberately use the word ‘explore’, as I am no an expert in this space and am myself trying to find the right answers) the following two important questions:
(i) why is each type of nutrient critical for a runner?
(ii) what are some good sources of proteins for vegetarians (something that I struggled with before finally finding a diet that suits me)?

So, let’s start with understanding the importance of different nutrients for a runner.

Carbohydrates
We all know that carbohydrates are the main energy giving food. Let us turn our attention to a slightly finer question – how much of it can we store in the body and how much do we need during a typical running event?
When we consume carbohydrates, these are broken into glucose and glycogen. Glucose is absorbed in the blood and circulates through the body – this is the most readily usable form of energy. Whatever energy is not needed immediately is stored in the form of glycogen reserves. A healthy human adult stores around 500gms of carbohydrate – around 400gms as muscle glycogen and around 100gms as glycogen in liver. Additionally, up to 25gms circulate through blood vessels in the form of glucose.
Now, let’s look at the next part of the question – how much carbohydrates do we need in a typical running event? Research indicates that in a typical running event a runner consumes around 3gms of carbohydrates per minute. This essentially implies that a well-nourished body has sufficient carbs to keep the body running for around 175 minutes [= (500 + 25) / 3]. Interestingly, this is quite close to the official cut-off time of 180 minutes for a half marathon.
If we look in terms of energy requirements, 500gms of carbohydrates represent around 2,000 Kcal of energy, while a runner like me (78kg) running a 21.1km stretch consumes around 1,780Kcal of energy (based on standard running calculators).
Two important observations before we move to the next nutrient:
  1. The amount of glycogen that can be stored in a healthy body is limited. Any excess carbohydrates that we consume gets stored as fats – so, there is an upper limit to the amount of carb-loading that should or can be done. Any excess gets stored as unwanted fat.
  2. Majority of glycogen (around 80%) is consumed in the muscle tissues. Hence, longer muscles are capable of storing more glycogen – next time you hear your coach say that stretching after running helps elongate and strengthen muscles, bear in mind this can potentially also increase your ability to store glycogen.
Some good sources of carbohydrates: Banana, low-fat yogurt, whole-grain bread, pasta, green vegetables and potatoes.
Fats
Human body comprises of much more fats as compared to carbohydrates. While the amount of carbohydrates a body can store is just around 500gms, around 10 - 20 percent of body weight (for a healthy person) can be made of fats. Research also indicates that 1 kg fat can provide around 9,000Kcal of energy. For a person like me (78kg), this means that my body can potentially store around 12 kg fats (or a source of 135,000Kcal energy). Now this is much more that what I would need to complete a half-marathon or a full marathon (or even an ultra-marathon).
However, the challenge is that unlike carbohydrates, fats cannot be readily consumed as energy sources. Deriving energy from fats is a relatively complex process. Fat is stored in the body in the form adipose tissue. To derive energy from adipose tissue, it first needs to be broken and transported to the tiring muscle. Moreover, releasing energy from the adipose tissue requires significant amount of oxygen. Typically, while running by the time there is a need to draw energy from adipose tissue (i.e. after depleting glycogen store), body is already breathless and availability of oxygen to release energy from adipose tissue becomes a limiting factor.  
Another important thing to note about fats is that these are of two types – saturated and unsaturated. Saturated fats are the ones that usually come from animal sources and carry significant health risks (including increased blood cholesterol level). Unsaturated fats are usually derived from plant sources and unlike saturated fats these fats do not carry health hazards. In fact, unsaturated fats provide some health benefits for heart.
So, what does this mean for us, the athletes? Primarily two things:
  1. Unlike carbohydrates, fats are available in abundance in human body and there is no need for ‘fat-loading’. This is an important point as many people end up consuming fats under the garb of ‘carb-loading’ prior to the race day.
  2. Amount of saturated fat intake should be limited but the diet should have appropriate level of unsaturated fats.
Some good sources of unsaturated fats (good fats): Olives, almonds, walnuts, nuts, peanut-butter, tofu, soy-milk, olive oil, soybean oil.
Water
Importance of staying well-hydrated in long-distance runs cannot be overemphasized. During long-distance runs body loses significant amount of water and sodium in the form of sweat. This loss of water and electrolytes is a common reason for the occurrence of muscle cramps.
Typical dietary intakes to avoid dehydration – 2 to 3 liters water per day and Enerzal (especially during the last few days leading to a running event).
Vitamins and Minerals
If we draw the analogy to the automobile engine that I started this blog with, vitamins and minerals are like lubricant oil for the automobile. Lubricant oil is not the fuel that provides energy for motion, but it is required to prevent wear and tear and ensure proper maintenance of the engine. Similarly, vitamins and minerals are nutrients that are required in small quantities for the body parts to function properly. These nutrients also help in strengthening the body’s immune system. There are different types of vitamins and minerals, each performing a specific function. Following table summarizes the most critical vitamins and minerals for an athlete and some common food sources. For brevity, I have confined the benefits to the ones most relevant for an athlete.


Proteins
Proteins are the nutrients that help in building muscle and expediting recovery / repair of damaged tissues during high intensity work-outs or long distance runs. Some runners tend to neglect protein, labelling it as ‘muscle-building’ food more appropriate for body builders. However, this is at best an incorrect practice. I usually think of protein intake in two phases:
  1. During the months leading to running events (or during off-season): This is the ideal time to work on body fundamentals and build muscle strength. For instance, it helps to develop more muscle around forearms and wrists. This helps to provide greater propulsive thrust from the swinging of arms during running. Similarly, it is critical to conduct strength training to prepare the muscles (especially leg muscles such as calves, quads, hamstrings etc.) for the stress-impact these muscles will undergo during the running season.  
  2. During the running season: If one is participating frequently in distance running events (say once in a month or two months), then the body needs quick recovery to repair the damaged tissues. Hence, here again, appropriate intake of proteins is critical.
An average human body needs around 0.8gms of protein per kg of body weight (daily). For athletes trying to build strength or recovering from a long-distance run, this requirement is considerably higher and is usually in the range of 1.4 to 1.6gms per kg of body weight. For me (78kgs), this implies a daily protein requirement of around 120gms. As a vegetarian (but consuming eggs), I often struggled to meet this requirement. However, with experimentation I think I have found a diet that largely serves my daily protein requirement – sharing below for the benefit of fellow vegetarian runners:
I hope the article provides some good 'food' for thought for runners looking to improve their nutrition to enhance their running performance.
