Ace your Race at the right Pace!

The month of November is here, and so is Airtel Delhi Half Marathon (ADHM). On the 29^th of this month, runners of different ages, professions and nationalities will get on to the roads of Delhi to experience the eighth edition of this vibrant high energy running event. Different runners would have their own reasons to participate in the event. There would be some who would be there to experience the joy of running, some others would be there to experience the euphoria and intensity associated with this mega-event, there would be still others who would be there to achieve their personal timing targets. In case you happen to belong to that last category of runners (with aspirations to achieve your timing target), this article is probably going to be helpful for you.

Over the past few weeks, several running friends have approached me to discuss the best way to pace a Half-Marathon. Incidentally, many of them aspire to achieve a timing target of sub-2 hours at ADHM. Well, the reality is that Half-Marathon is a long distance and a lot can go right or wrong depending on how one paces the run. Additionally, there is no unique way in which two different runners can approach a race, even if they are gunning for the same target! In this article, I intend to illustrate a simple approach in which one can break the 21.1 Km (seemingly long and unmanageable stretch) into somewhat simpler and more easily manageable segments. For the purpose of illustration, I am taking the example of a timing target of 2-hr finish for the half-marathon.

Step 1: Assess the overall objective

If you are planning to achieve a timing of 2 hours for a half marathon, you need to achieve an average pace of 5:41 (mins:seconds) per Kilometer.

Average pace for 2 hr finish = 120 mins / 21.1 km = 5:41

The first question to be answered even before we get down to crafting a pacing plan is to ascertain if this is the right timing target. This is more of a subjective introspection than anything else. For instance, if you have recently clocked sub 2 hrs 10 mins then probably with a little bit of stretch there is merit in targeting 2 hours at ADHM. However, if your latest timing has been upward of 2 hrs 15 mins then probably 2 hrs target for ADHM is too aggressive.

Step 2: Understand the constraints and race-day conditions

This is probably the most critical step to appropriately plan a run and primarily involves two aspects – (i) understanding the race day conditions, and (ii) Understanding the current level of body conditioning (and pragmatic expectations of one’s own abilities). These are explained below:
  

Understanding race day conditions

There are several aspects that one needs to look at to understand the race day conditions. For instance, some of these could be (non-exhaustive list below):

• Negotiating crowd: If you are targeting a sub-2 finish, chances are that you have been lined up in sections B, C or D in the race start sections. This means you would have to negotiate crowd in the initial few kilometers, which means you will essentially run at a pace slower than the average target pace (which is actually not a bad thing as it allows the body to warm-up and is a desirable thing to do – crowd or no crowd).
• Race timing: Most of our local running events are designed to start the race at around 5:30 – 6:00 am. However, the Half-Marathon run at ADHM has a staggered start with section A starting at around 7:10 am, and then other sections starting with a time offset of around 5 mins. Hence, you will likely be running till around 9:15 to 9:45 am, and by that time sun would have assumed full effect. If you are one of those who does not necessarily enjoy running in the sun (like me), this may have an implication on your running pace in the last 4 to 5 kilometers.
• There may be other race day considerations such as elevation, humidity level, availability of hydration points etc., which may need to be factored into your running plan (some of these may not be big considerations for ADHM, as the course is fairly flat and the weather conditions are the best that one can expect for a running event; however, these would be big considerations for an event like Airtel Hyderabad Marathon).

Understanding current level of body conditioning
This is critical so that one can appropriately plan a pace for different segments of the race. Again, for the purpose of illustration, some of these considerations could be:

• Split timing: Unless, one is an elite runner, chances are that we are not gunning for negative splits (second half faster than the first half). During my training runs, I have found that I tend to take approximately the same time for the first 11 km, as I take for the remaining 10.1 km, i.e. in terms of timing, my time at 11 km mark tends to be the mid-point of the race. This could be an important input into my racing plan.
• Pace towards the end: Similarly, during the training runs one may observe that in the last 4 -5 km, average pace is around 20 – 25 seconds slower than the average target pace for the race. This is a common observation as by that time fatigue has already set-in and it adversely impacts the pace.

The above are some of the considerations that one may factor-in to develop a pacing plan. Please note that these are not exhaustive considerations, but just trying to illustrate what kind of aspects one can think through. Once we develop a thorough understanding of these constraints and considerations (and that really is the purpose of training runs), the next step is to put it all together in the form of actual race day pace plan. This is important as each consideration really has an implication in terms of how best to pace the race. For example, following figure highlights how each of the above considerations can be translated into a pacing implication:

No.	Constraint	What does it mean?	Pacing implication
1.	Timing at 11 km mark approx. represents the half-way mark (in terms of timing)	For a 2-hr target, need to cover first 11 km in 60 mins and next 10.1 km also in 60 mins	Average pace for: first 11 km is: 5:27 next 10.1 km is: 5:56
2.	Negotiating crowd in the first few kilometers will mean slower than average target pace	Average target pace for first 11 km is 5:27 (see point 1 above), but average pace for first 3 km would be around 20 - 25 seconds slower (let’s say 5:50)	Simple math will show that avg. pace:   for first 3 km is 5:50 for km 4 to 11 is 5:19 (this will allow one to achieve overall average pace of 5:27 for first 11 km)
3.	Fatigue and sun in the last few kms will slow me down	Average target pace for last 10.1 km is 5:56 (see point 1 above), but average pace for last 4.1 km would be around 10 – 20 seconds slower (let’s say, 6:10)	Simple math will show that avg. pace: for last 4.1 km is 6:10 for km 2 to 17 is 5:47 (this will allow one to achieve overall average pace of 5:56 for last 10.1 km)

Step 3: Put the plan together

As illustrated in the steps above, based on an understanding of race day conditions and our current body conditioning, we have segmented the overall 21.1 km into 4 segments as shown below:

Step 4: Follow the plan

Once you have done the due-diligence of identifying what formula works for you, the next important (and probably the hardest) step is to stick to the plan on the race day. For instance, the plan in the case we analyzed above is shown below: 

There invariably would be an urge to go faster than the planned pace in the initial few kilometers. However, it is important to keep following points on the radar:

• Do not try to beat your plan; after all, it is your own plan! If at all you had the ability to do better than the plan, it should have been factored into the plan in the first place.
• Having said that, it is important to listen to your body signals – if you constantly get a message that you can go faster than the plan (may be because of race day Adrenalin), conserve that energy for the last segment. Do not be lured by the desire to go faster in the initial few segments and risking your performance in the closing stages of the race. Remember you are more likely to realize your best timing potential by finishing strong (and not by starting strong).

I would just reiterate that each individual has to identify his / her own pacing plan for the race day (based on an understanding of self as well as the race conditions). The better one understands the real conditions and factors them into the pacing plan, the higher is the likelihood of beating the target on the race day.

All the best for ADHM 2015 and looking forward to meet you on the race day!
