It was highlighted that the original article [1] contained an error in the proportions reported in the Results, in the Representativeness of registered parkrunners section. This Correction article shows the incorrect and correct statement.

Incorrect:

With respect to age, the survey over-represented the three age groups 35–44, 45–49, 50–54 years compared with registrants (35.8% vs. 18.4%, 16.2% vs. 6.1%, 11.5% vs. 4.1%), and underrepresented the three age groups 18–24, 55–64, 65 or older (2.4% vs. 6.3%; 10.8% vs. 35%; 3.7% vs. 10.3%) p < 0.001. For both the survey sample and parkrun registrants the 25–34 year-old group comprised 20%.

Correct:

With respect to age, the survey over-represented the five age groups 35–44, 45–54, 55–64 years, compared with registrants (35.8% vs. 31.0%, 27.6% vs. 17.2%, 10.8% vs. 5.9%, 3.7% vs 1.7% respectively), and underrepresented the two age groups 18–24 and 25–34 years (2.4% vs. 10.7%; 19.7% vs. 33.6% respectively) p < 0.001.
