Factors affecting performance at Scottish parkrun events
This study provides the first large scale investigation of the fitness benefits of parkrun by analysing performance of over 1.5 million participations in Scotland. Clear patterns in participation and performance at parkrun events in Scotland have been identified which could be used to increase the beneficial impact parkrun has on communities in Scotland and beyond. Although traditional mass participation events such as annual marathons might not increase community activity levels [3] the weekly parkrun model does seem to provide a clear public health benefit. For example, this study reveals that performances at parkrun improve with the number of times participants attend parkrun.
There is a substantial and continuing decline in the average performance of participants identified by the study. This is not predicted if parkrun simply attracted existing runners. The decline is not the result of participants becoming less fit, indeed this study identified that individual participants are improving their performance over time revealing a public health benefit associated with registering for parkrun. Consequently it seems likely that the decline in overall performance is being driven by decreasing fitness levels of newer participants. This is supported by the negative association identified between registration number and performance revealing that the most recent registrants exhibit the lowest performance. There is a clear pattern of continuing decline over time in the performance of the new registrants suggesting parkrun is becoming increasingly attractive to the less active. It seems that the parkrun model of mass participation is successfully increasing activity levels of the less fit and is becoming increasingly effective at doing so. The fact that participants increase their individual performance over time and with number of participations shows that parkrun is providing a public health benefit and the impact of that benefit is likely to be increasing as parkrun becomes more inclusive.
Gender differences in performance
The study also found a substantial difference in the performance levels of men and women. This fits with the relative patterns of inactivity associated with gender [2,4]. The lower level of starting fitness of women is also highlighted by the finding that women improve their performance faster over time and with increasing numbers of completed events than male participants. This shows that women on average benefit more than men from parkrun, something that might potentially be used to encourage more women to participate. It is also noteworthy that the gender gap was significantly wider when only the initial run of each participant was considered showing that men perform a lot better than women on their first run also indicating a higher initial fitness of men. It is also noteworthy that this gap is also narrowing over time suggesting that parkrun is also increasingly attracting less active male participants.
The gender differences in performance could be partly explained by greater competitiveness in men but the lack of comparable gains in fitness in men suggests it is more likely that women are comparatively less fit when they join. One factor making men more competitive could be a higher engagement with the increasing gamification of parkrun. parkrun have received criticism for ranking individual times and maintaining course records when parkruns are marketed as not being races [8]. However, these are likely to be important motivatory factors for many to take part in parkrun. Furthermore, some elements of the gamification of parkrun are not biased towards those with higher fitness levels such as parkrun tourism [25]. Additional gamification of parkrun could be targeted towards statistics that are not associated with absolute performance. Therefore, promotion of statistics related to improvements in individual performance in addition to ranking absolute performance might be more beneficial and could increase participation by those sections of the community that would benefit from it most. For example, these could include performance score personal bests (PBs) in addition to absolute PBs.
Gender differences in patterns of participation
This study identified several factors associated with the proportion of male participants at events. Those events on faster surfaces and which are closer to other parkrun venues had more male participants. Older participants were more likely to be male, although among young adults there were actually more female participants. In Scotland it appears new registrants are more likely to be female. Despite this it is only the remotest parkrun events that have higher numbers of females than males participating. The difference in registration patterns and attendances suggest there might be greater barriers to females attending parkrun events particularly in the older age groups. The higher level of participation of younger female adults compared to older female adults suggests that the barriers to female participation might be cultural and associated with older generations. Younger women who are more likely to have childcare limitations are more likely to participate suggesting that parkrun’s strategy of allowing buggies and children to run has successfully remove one key barrier to female participation, childcare responsibilities.
Remote event venues could have a greater sense of community identity and as a result feel more welcoming. They might also have a smaller field with fewer elite athletes making them seem less intimidating to slower participants. The slowest mean finishing times at Scottish parkrun venues are generally at the remotest events, some of which, such as Thurso and Agnew, have developed a culture of walking [18]. The development of strong social identities from being part of the parkrun community has been found to be an important component of participation and gaining health benefits from parkrun [26,27]. If remote parkruns have a stronger social identity then they might be having a disproportionately large impact on the health of the communities they serve. The proportion of female participants was also higher at events run on trails and grass compared to hard surfaces. This could be because these parkruns are at more pleasant locations which could preferentially attract priority groups such as women and those with mental health issues [16]. Tarmac and concrete surfaces might attract more competitive runners and make those events feel less welcoming to the less fit. In Scotland the tarmac and concrete events are also more likely to be in city centre parks with larger numbers of attendees with could also make them feel more intimidating. This might contribute to the reason why ethnic minorities who have greater access to venues are less likely to participate.
The strong association between age and the gender of participants suggests that older women are the least likely to take part in parkrun. This could be a result of long-hold social beliefs acting as barriers such as the expectation that women should not participate in sports. It could be fruitful to explore factors associated with relapsing at parkrun, for example are older women more likely to relapse after attending a single event? Another barrier to participation in physical activity is the misconception that it is potentially dangerous especially for those with long term health conditions. Evidence suggests that the health benefits of attending parkrun considerably outweigh any risks for most groups [11,28,29].
Male participants could also be playing an important role in driving some of the patterns identified by this study. For example, the higher proportion of female participants at events on slower surfaces could be driven by male parkrunners preferentially attending events on faster surfaces. Although male participants selecting events on the basis of their speed could generate skewed gender ratios in areas where there are several events within close proximity of each other, this would not be expected to generate the higher number of female than male participants present at remoter events where there no other local options about which parkrun to attend.
Age of participants at Scottish parkrun events
The average age of participants at parkrun events has started to show a consistent increase despite the average age of those registering for parkrun declining. A key factor in explaining this apparent contradiction could be the establishment of Junior parkrun which provides 2km events for those aged between 4-14. Junior parkrun events were not included in the study but participants use the same registration numbers. This is likely to have encouraged more registrations of children for parkrun. The higher number of boys participating than girls in 5km parkruns might suggest that girls find junior parkruns less intimidating than 5km parkruns. It is also possible that decisions by parents are impacting this trend.
One very interesting finding was the discovery that the highest female gender ratios were achieved in the 20-45 age group. This suggests that barriers to activity as a result of childcare responsibilities might have been reduced by parkrun by allowing participants to run both with buggies and with children. It is older females of an age where they are least likely to have childcare responsibilities who are also least likely to participate. This could potentially be a legacy of the lack of equivalent opportunities available to them to participate in physical activity when they were of a child-bearing age.
Limitations of the study
One potential limitation of the study is the use of AGPS as an indicator of fitness. The ideal measure of fitness would be the maximum achievable AGPS of a participant on the day they completed an event. However, participants are not likely to run at their maximum level at each event especially as parkrun is not marketed as a race. This study identified that between participant variance far exceeded within participant variance. Consequently, even though participants will not always run at their maximum level at each event the vast majority of the time they will run reasonably close to it and AGPS are likely to be a reasonably robust indicator of fitness. Despite the variation introduced by participants running at different levels compared to their maximum attainable performance this study still has identified clear bidirectional patterns in performance with individual performances increases and overall performances declining.
The study was also limited by the available data. Protected characteristics such as ethnicity and socio-economic group, which are likely to be associated with attendance and performance at parkrun events, are not publicly available and therefore. could not be explored in this study. There are likely to be other factors interacting with those identified in this study that are yet to be explored and could alter some of the conclusions drawn. For example, are the pattern seen in females present in all social and racial groups?
One other limitation is that this study was restricted to Scotland and it remains to be seen whether these findings translate to other areas of the UK and beyond. Conducting similar studies in other regions would be needed to determine the generality of the findings of this study.
Implications for parkrun
This study has identified significant patterns in the participation of parkrun events in Scotland. parkrun in Scotland seems to be becoming more inclusive as less fit individuals increasingly take part. The proportion of women taking part has also increased in parallel with this reduction in performance. Women are particularly willing to take part in the most remote isolated venues so these events are likely to be having a disproportionately large beneficial impact on their local communities. Indeed, remote parkrun events have more female than male participants suggesting that some barriers to women participating present at other events might be absent from remote Scottish parkrun events. Alternatively, there could be more barriers to male participation in more remote locations or perhaps people that live in remoter locations are naturally more likely to be active in their local environment and so participation levels are more even between genders. parkrun could try to encourage the creation of events in more remote locations. It might be interesting to explore the proportion of the local population who attend these events to determine if it’s higher because more women participate, or lower because fewer men do, as they have other potential options for outdoor pursuits. The creation of more events in remote locations might accentuate inequalities in access to parkruns with respect to socio-economic background, however parkrun have identified their locations are skewed towards providing easier access for both lower socio-economic classes and ethnic minorities [13]. This is likely due to the relatively high number of locations in inner city parks compared to more rural areas. Thus, creating more remote events might help remove the bias towards access to parkrun in urban communities. Furthermore, an increase in the number of parkruns will not reduce anyone’s existing access but only increase access to those currently lacking a local event. Another advantage of increasing the number of parkruns in remoter areas is providing a more local event for existing parkrunners in that area so reducing their travelling time and the impacts of their travel on the environment.
The proportion of female participants was also substantially higher at events run on trial paths and grass. parkrun could encourage the creation of softer surface events in areas dominated by hard surface events to provide a less competitive alternative venue for female participants. Furthermore, the parkrun practice initiative might be increasingly effective if practitioners prescribe not just attendance at a parkrun event but at an event that a new, relatively unfit, participant will more likely return to. Finally, an increase in gamification targeted towards improvements in performance could also encourage more participation by those individuals who would benefit the most.
A study of why people stop attending parkrun events would also be useful. For example, are women more likely to relapse after attending a single event? Is this more likely to happen at larger, more urban events with a greater proportion of elite athletes? Understanding what factors are creating barriers to continued participation could be as useful as studying patterns in participation itself.
