For the third year in a row OHV has recorded record participation in its events. Across 25 events the total was 4671, that's 187 per event. Our CSW classic events were each around this number, while rogaines (391) balanced the smaller events. Rogaining continues to be the star performer, but foot orienteering enjoyed solid growth, and a great response from new course planners and mentors. The data series goes back to last century, see the numbers here.
