Who will be the next to make it on to the Marathon Swims Hall of Fame? A big thank you to our Marathon Swims Partners. Date tbc. London's marathon of swimming returns to the London Aquatics Centre in date tbc. Take on the Marathon 10k, Half Marathon 5k or the 1k Challenge. Or team up with a friend to take on the Team 10k. This sell-out event has been hosted at the LAC since Also, mid-race positions were indicated relative to the total participants in each race Figure 2.
Swimming paces of successful swimmers were compared with a repeated measures analysis of variance according to the race distance 5-km, km, and km , the race lap first to second in the 5-km, first to fourth in the km and first to tenth in the km race , gender male or female and competitive level medalist or finalist. Planned repeated contrast tests between successive laps were carried out.
The race tactical behaviors mean velocity, mid-race positions and gap-times were related to the end race results by using Pearson correlation coefficients, being 0. Performance density of the top swimmers indicating velocity differences between first and tenth classified swimmers was 0. Table 1. Figure 1. Changes in the swimming pace in relation to the mean race velocity reached maximum values in the last lap of races, with a magnitude of 6. Intra-individual coefficient of variation in the lap velocity of the longest event km reached 6.
In relation to the tactical positioning Figures 2 — 4 , successful swimmers of the 5-km events males and females were located at the 2. However, in the second part of the race, their time gap with leaders decreased to less than 10 s and their partial positioning was within the top swimmers. Successful female swimmers in this event, in turn, showed a more delayed positioning in the first half of the race by locating in the rear part of the group and more than 20 s behind leaders. Figure 2. Mean partial positioning relative to the total participants of the successful participants top on the 5-km, km, and km events of the FINA World Swimming Championships error bars removed for clarity.
Figure 3. Figure 4. Mean time gap s with leaders of the successful swimmers top in the 5-km, km, and km events of the FINA World Swimming Championships error bars removed for clarity. In the 5-km race, however, the swimming velocity of the female swimmers in each race lap first and second was related to a better final race position.
For the mid-race positions and time gaps with leaders, these parameters were not related to the 5-km or km end race results, except for the females 5-km event. Tactical positioning, however, showed meaningful correlations with the race success in the last three laps of the km race distance, both for male and female swimmers.
Table 2. Relationships between lap swimming velocities, partial positions and intermediate gaps from the first to the last lap and the end race results for the top competitors males and females of the 5-km, km, and km races of the FINA World Swimming Championships. The present research aimed to compare the pacing profiles and tactical strategies of the open water swimmers men and women competing at the 5-km, km, and km races of the FINA World Swimming Championships.
Successful swimmers in the three events performed a negative pacing profile with increasing swimming velocities at the end of races. However, the dynamic of pacing profiles as well as the tactical positioning of the competitors depended on the race distance and on gender. Mean swimming paces in the 5-km, km, and km races showed clear differences from race to race and represented different swimming intensities according to the lactate threshold velocities of elite freestylers Pyne et al.
A high level of competitiveness was demonstrated by the mean swimming velocity of the top swimmers, similar to that of recent Olympic km races 1. The density of performances of the top swimmers in Budapest was also greater than previous 5-km 1.
These data disagree with previous results from non-conventional open water races such as the Manhattan Island Marathon Swim Knechtle et al. However, as previously observed Knechtle et al. The body composition of female athletes, with a more favorable percentage and distribution of fat tissue Mclean and Hinrichs, , would provide them with more buoyancy and less drag to perform better in the longer distances Baldassarre et al.
In relation to the pacing variations, female swimmers did not show lower changes in velocity than men as could be expected due to their physical features but also to their lower tendency to take risks in a race context Deaner et al.
However, their end race spurts were of a lower magnitude than their male counterparts in line with the lower speed variations reported in the literature Abbiss et al. This strategy had been previously reported a successful approach by proficient Marathon runners who want to be in control of the race Hanley, , as it prevented less capable competitors to increase pacing in the second half of races. However, in the last lap of the race, they performed a dramatical end spurt by increasing swimming velocity by 9.
This end race spurt was greater than that of 1. Finally, in the km races, competitors showed a more variable pacing profile than in the shorter events. Swimming paces in the first splits of the race were relatively slow 6—7 s slower per m than the km competitors but then, progressively, they were increasing from lap to lap although not in a linear manner Figure 1.
Probably, swimmers in this event 4-h long organized their energy output according to external race conditionings and giving less weighting to their physiological status. When comparing the pacing profiles of finalists and medallists open water swimmers, results indicated similar swimming velocities and race dynamics for the most of race distance between them, but a greater ability of medallists to increase swimming pace at the end of races Figure 1.
This had been previously observed in Olympic track races Thiel et al. In general, the pacing strategies of successful swimmers in the 5-, , and km races showed clear differences with those of other endurance disciplines.
Running competitors had been reported 1 to adopt initial paces considerably faster than the mean speed of the race Tucker et al. However, elite open water swimmers in the present research especially in the km and km races did not adopt a fast pace approach at the beginning of the race but they performed the slowest pace in the first split both men and women.
Also, in all the 5-km, km, and km events, successful swimmers did not decrease pace in the second half of races, but they presented negative pacing profiles instead. Mean times of top swimmers in the second part of races were approximately 2, 3 or 7 min shorter for the 5-km, km, and km events than in the first half. In relation to the end spurts, open water swimmers seemed to speed up velocity over a greater proportion of race distance compared to other endurance disciplines, although this information should be confirmed by a greater temporal resolution of intermediate splits Thiel et al.
Open water swimmers may deliberately seek to save energy in the initial stages of races by swimming slower than an ideal pace and then regulate pace according to the race configuration in packs to avoid gaps that would decrease the drafting effect. When examining the tactical positioning of successful swimmers in the different race distances, the 5-km event showed a different profile from that of the km and km races.
Swimmers in the shortest event situated in the leading part of the main group from the early stages of the race Figure 3 and with a narrow gap from leaders shorter than 5 s or approximately 5 m. In the longer events km and km , successful competitors adopted a more conservative positioning in the first half of the race by locating in the mid-part of the main group. The time-gap with leading swimmers, in these events, did not exceed 15—20 s which represented according to the swimming velocities a maximum distance of 30—35 m.
This had been previously observed in the km race of the World Swimming Championships Rodriguez and Veiga, , but it had not been ever reported with time gaps in order to fully understand race dynamics. The successful km swimmers, on their behalf, did not achieve the leading positions until the last lap of the race [as previously observed during the World Championships Rodriguez and Veiga, ] assisted by their greater end spurt compared to the 5-km or km events.
Differences in the tactical positioning between events probably depended also on the different performance densities of races, as the greatest density of the km was contrary to the lowest density observed in the km race. Regardless of the event distance, it was noticeable the ability of medallists across all distance events to maintain time gaps with leaders no longer than 10—15 s in the second half of races.
These time-gaps which would represent distance-gaps no longer than 20 m allowed medallist to be in control of the race as they were able to cut them down within the 25—30 min duration 2. These race behaviors highlighted the influence of the extrinsic factors on the tactical decisions of elite open water swimmers Renfree et al.
Other extrinsic factors that could also influence the race outcomes were specific aspects of the race venue like the structure of the course, currents, water temperature, …etc. Abbiss and Laursen, By continuing to browse our website, you agree to our use of cookies.

Tunisia's Mellouli became the first African male swimmer to win an Olympic gold medal in an individual event when he won the m freestyle with a dramatic victory over Grant Hackett AUS in a star-studded field at the Beijing Olympic Games.
In Tokyo he is competing in his sixth Olympic Games and is the only swimmer to earn an Olympic medal in pool and open water events at the same Olympic Games.
In the London Olympic Games Mellouli claimed bronze in the men's m freestyle and finished his campaign with a spectacular gold in the men's 10km in Marathon Swimming. In he won the qualifying race and 9 years later he finished 10th in a field of 51 men in the June 20 qualifier. Mellouli served as Tunisia's flag carrier in the Olympic closing ceremony and in the opening ceremony.
If he finishes first, he could become the first man to win two gold medals in this event. The Tunisian is the only athlete in the event to have won two gold medals in the Olympic Games. A review of the finish line cameras declared Weertman the winner and he became the third Dutch athlete to win Olympic gold in Marathon Swimming. The trifecta from the Netherlands swimmers means that their National Olympic Committee NOC holds claim to the most Olympic gold medals in the discipline.
