Active Network, a software and registration data provider for more than 125,000 endurance industry events spanning more than 16,000 organizations, released a U.S. map scaling the most active states per capita.

Surprisingly, North Dakota was ranked the most active, with Washington D.C. coming in second and Hawaii third.

Based on Active’s data, nine of the top 10 most active states and 15 of the 23 somewhat active states are known to have harsh winters and temperate summers.

“Milder summers may play into the increased participation rate of these more northern regions. The prevalence of themed holiday runs and/or the tendency of extreme athletes to be undeterred by winter conditions could also bump those states to higher participation rates,” said a representative for the company.

Furthermore, the western U.S. displays the largest number of somewhat active states, and also shows the largest variety of event types.

The top 10 most active states:

1) North Dakota
2) Washington D.C.
3) Hawaii
4) Vermont
5) Maryland
6) Colorado
7) Wisconsin
8) Alaska
9) Massachusetts
10) Utah

The top 10 least active states:

2) West Virginia
3) Mississippi
4) South Dakota
5) Wyoming
