Background: The 56km Two Oceans ultra-marathon (TOM), in Cape Town, South Africa, was cancelled in 2020 and 2021 because of the COVID-19 pandemic. Since most other road running events were also cancelled during this period, we hypothesized that most athletes who entered TOM 2022 would be inadequately trained, which would negatively affect performance. However, many world records were broken post-lockdown, and therefore the performance, specifically of the elite athletes, during TOM might actually improve. The aim of this analysis was to evaluate the impact of the COVID-19 pandemic on performance in TOM 2022 compared to the 2018 event.
Methods: Performance data during the two events, as well as the 2021 Cape Town marathon, was extracted from public databases.
Results: Fewer athletes entered TOM 2022 (N.=4741) compared to TOM 2018 (N.=11,702), of which more were male (2022: 74.5% vs. 2018: 70.4%, P<0.05) and in the 40+ age-group categories. Compared to 2018 (11.3%), fewer athletes did not finish TOM 2022 (3.1%). Only 10.2% of the finishers completed the 2022 race during the last 15-minutes prior to the cut-off, compared to 18.3% in 2018. There were no differences in the average 2022 finishing time of the subset of 290 athletes whose times were compared to their 2018 performance. There was no difference in the TOM 2022 performance of athletes who had completed the 2021 Cape Town marathon, 6-months earlier, when compared to those who had not entered the marathon.
Conclusions: Although there were fewer entrants, most athletes who entered knew that they were adequately trained to complete TOM 2022, with the top runners breaking course records. There was therefore no impact of the pandemic on performance during TOM 2022.
