Pacing in Olympic track races: competitive tactics versus best performance strategy
Transponder data from the Beijing 2008 Olympic 800 m to 10,000 m finals (133 finalists) were used to describe pacing. Six of eight speed-by-distance patterns differed from those reported for world records. Running speed varied with a coefficient of variation of 3.6-11.4%, and in the long-distance finals runners changed pace every 100 m by a mean of 1.6-2.7%.
Runners dropped from the field settled into a stable speed and finished with an endspurt; top contenders used variable pacing to separate from the field, and every race was decided during the final lap.
Participants
n=133 finalists in the Beijing 2008 Olympic track finals from 800 m to 10,000 m. Sex split is not given in the abstract.
Protocol
Publicly available data from four transponder antennae under the 400-m track.
Individual pacing patterns visualised as speed-by-distance plots.
Questions: do Olympic finals differ from world records; how variable is the pace; do runners face catastrophic events; what is the winning strategy.
Key Results
Six of eight race patterns differed from the patterns reported for world records.
Coefficient of running speed variation: 3.6-11.4%.
Long-distance finals: pace changed every 100 m by a mean 1.6-2.7%.
Runners who fell off the pace of the field settled into a steady speed and still produced a finishing kick (endspurt).
The leading contenders changed pace repeatedly to break away from the rest of the field.
All races were decided during the final lap.
The authors read dropping off the leading group as an active step, the result of interactive psychophysiological decision making.
Practical Application
"Should I race a championship final like a time trial?" — the best do not: across 133 finalists in the Beijing 2008 Olympic 800 m to 10,000 m finals, six of eight races had pacing patterns unlike world-record runs, speed varied by 3.6-11.4%, long-distance runners changed pace every 100 m by 1.6-2.7% on average, and every race was decided on the final lap.
For a tactical championship race, prepare for pace changes and a last-lap kick, not only for an even target pace; the authors note that these micro- and macro-variations may have implications for training programmes.
Getting dropped is a decision: the dropped runners settled to a steady pace and still produced an endspurt. Inference, not tested here: once a runner cannot hold the leaders' surges, switching to their own steady pace is how they protect their finishing place.
Not from this paper; the base's own practice: for a time goal in a paced or time-trial race, even pacing remains the default (REF-010); this paper describes racing for place.
Limitations
One Games (Beijing 2008), elite finalists only; descriptive, with no physiological measurements.
Transponder splits at fixed points smooth out very short pace changes.
Sex split and per-event results are not given in the abstract.
