For this study, we analyzed 107.9 million race results - by far the largest in history. They include participants from 209 countries and a total of over 70 thousand events. The time frame is between 1986 and 2018.

Our dataset covers 96% of US race results, 91% of the race results from the EU, Canada, and Australia and a smaller sample from Asian, Africa and South America.

The study was done in collaboration with the International Association of Athletics Federations (IAAF) and presented in China in June 2019.

The trends of mass participation running

Running is huge and has quite a big following, but as we can see from the chart below it's declining in the last two years. This is mainly due to a decline in participation in Europe and the US. Participation in Africa and Asia is very much on the rise, just not enough to compensate.

The participation in running races has peaked in 2016 with a total of 9.1 million results and then it declined to 7.9 million (a decline of 13%) in 2018. If we look at the change in participation in the last 10 years there is an increase in participation of 57.8% (from 5 to 7.9 million participants).

5-kilometer races and half marathons have the highest numbers of participants (2.9 and 2.1 million participants in 2018, respectively). But also have suffered the biggest decline in participation in the last 2 years. Half marathoners have declined by 25% (from 2.9 million) in the last 2 years. and 5K participants have declined by 13% (from 3.4 million).

10Ks and Marathons have a more modest following - 1.8 and 1.1 million participants respectively in 2018. But it's quite stable over the last few years - the participation rates have fluctuated less than 2% the last 2-3 years.

It's also interesting to see which do people prefer - smaller or bigger races. We have chosen 5,000 participants as the boundary.

Our analysis shows that almost equal amounts of people enter small races as do big races, with a slight preference for the bigger ones. On average big races attract 14% more participants.

Also, the participation trends for both types of races follow a similar trend. The participation in big races is on the rise until 2015 and for small races, it's on the rise until 2016. But the decline in participation in the smaller races is more pronounced - 13%, compared to the one for the bigger races - 9%.

When we talk about running races we usually think about marathons, however, in the last few years, they account for just 12% of the results (shrunk from over 25% at the beginning of the century). This has led to growth in half marathon participation, an increase from 17% to 30% of total participants

The proportions of participants in 5Ks and 10Ks are quite stable, but still experiencing some growth - 5K participants have increased by 3% on average, and 10K participants by 5%.
