Pacing
The following article regarding pacing should be kept in context.
There are exceptions at all levels. What I address here, is
what should be the rule, not the exception. Specific race
strategies may be employed depending on the competition, strengths
and weaknesses of you and your opponents and psychological
factors as well as your own current conditioning.
Two things
are clear:
1. Whether you are pacing in races, time trials; trying to
set personal records or beat your arch-rivals, you have to
know your pace.
2. Unless you are clearly a superior runner, even pacing with
a slightly faster second half than first half is the best
strategy.
Research
indicates, through careful analysis of split times of record
and championship races, that the optimal race pacing strategy
is to use 51% of your total projected time in the first half
of the race and 49% of your time in the last half. That means
you run faster in the last half – also called running
“negative splits”. Virtually every distance from
1500 meters and longer are optimally run with the negative
split strategy.
Just to
check this out, I reviewed some results from last year and
found the following.
•
In the World Cup Marathon Championships the top 6 men and
top 5 women had negative splits. All those slower than those
places did not. Furthermore, those top 6 men and 5 women went
through the halfway marks together in their respective races.
In the end, 58 seconds separated those men, and 1:30 separated
those women. The winners pulled away mostly in the final miles.
As you
can see in the marathon splits, it takes endurance (the ability
to run a long distance), stamina (the ability to sustain a
specific pace over a specific distance) and speed. Yes, SPEED!
It was the runner who could run fast at the end who won. They
all could run the distance (endurance). The all maintained
fast paces for the distance (stamina). But, the runners who
broke away to win had the ability to pick up the pace and
run faster while they were fatigued. They were not just hanging
on or trying “not to slow down” or trying to outlast
the other runners.
•
Even in the IAAF 10k track championship races the top three
in both the men’s and women’s races ran negative
splits. The pattern was the same. All went through halfway
together. But, it was the one who finished fast. 11 seconds
in the men’s 10k and 3 seconds in the women’s
– all made up in the last laps. These were not slow
tactical races set up for a sprint. The men’s times
ranged from 26:49-27:01 and the women ranged 30:04-30:07.
These are some of the fastest times ever run.
•
Meb Keflezighi recently won the US Olympic Trials 10k. 13
of his 25 laps were less than one second off his average pace.
Other than a slow 2nd lap and very fast last lap, all laps
were within 2 seconds of his overall average.
•
Deena Drossin in winning the women’s Olympic Trials
10k had 18 of her 25 laps within a second of each other.
Compare
these efforts to both your track workouts and your recent
races. Do you follow the same pattern that the most successful
runners do? Even pacing is the most energy conserving approach
to racing. Making surges to pass someone wastes energy. Charging
up hills wastes energy. Charging down hills pound your legs
and may leave you fried for the rest of the run (just ask
those downhill marathon race veterans). The research indicated
that the worst results came from fast starts.
And for
cyclist, the same holds true! Research indicates that even
pacing yields faster overall cycling times/speeds with the
even pace strategy.
It is
easier said than done. When you are fresh, you have the energy
to burn. You want to go out and attack. Sometimes, we suffer
under the delusion that “it just might be my day and
I will sustain this pace to the end – it’ll be
my big break through!” The physical consequences are
worst in an event like the marathon. But, the results and
disappointments are just as real for the 5k.
So, how do you prepare yourself?
• Run at your goal pace so that you can pick it out
anywhere and anytime.
• Run speed work, it separates the better runners.
• Run quality workouts with your fastest running towards
the end.
• Know your course and train for it specifically.
Here’s
a fun game to play. Run on a track. For each 400 meters (lap)
check your time. When you can keep all your laps within ONE
second – you’re getting good. Add your total time
deviance from your goal time. If your goal is 90 seconds,
whether you run 89 or 91 seconds, you are a second off. Keep
adding those variances (89 and 91 do not cancel each other
out!). Now, your goal is over time to reduce your cumulative
deviation from your goal. Do this as part of your track workout
or for a goal paced distance run on the track. It’s
a great way to learn your goal pace.
