Introduction
•
The ability to regulate pace is
dependent upon the ability to make
prospective judgments regarding the
metabolic demands of the exercise
against the actual metabolic
capacity.
•
Modulations in pace, are manifest in
order to prevent a complete
depletion of the finite anaerobic
capacity.
•
Cognitive judgment is set within the
context of a continuum from: ability
to anticipate metabolic demands and
select an appropriate strategy
through the accumulation of prior
experience for completion of such a
task that has a known end point.
Introduction
•
Pacing ability is a skill and
would benefit from repetition as
an individual becomes better
able to regulate effort to evenly
pace or achieve desired splits.
•
Experience (number of prior
marathons), age and race
speed shown to be of little effect
in marathon pacing while sex
was a robust indicator.
•
The ability to regulate pace is a
function of both the experience
of the individual (volume of
exposure to the associated
biological and psychological
sensations) and cognitive
developmental status

Method
•
Participants: 777 runners competing in London marathon 2015
Males: n= 384, Females: n= 393
Whole group responses
Male and female responses
Ressponses according to age
Responses according to prior experience

Responses according to prior experience
Conclusions
•
Data shows that accrued experience has almost no association (~8%) with pacing success and
accuracy confirming previous works of Deaner and co-workers 2015, coupled with no effect for
age or sex.
•
Race speed is associated with pacing accuracy and suggests either a function of training
volume in agreement with Green and colleagues 2010 or associative effect with physiological
function.
•
Irrespective of age, sex, experience of ability all runners exert to much energy in the early
phase of the race showing a marked slowing effect against even pace prediction implying either
(a) more caution at the start or (b) focusing on official pacers as guide runners in order to
maximise their race experience.
