ARDF USA Championships 2021 – Sprint Results

Filed under: Event Results,Latest News,Radio Orienteering by Imre Polik on October 14th, 2021

The 2021 ARDF USA Championships started this morning with the Sprint event. 21 competitors from all over the country showed up at the start line in various age categories. We were all glad to be back competing after a two year hiatus.

Thanks to Carlie, Don and Jerry for their help with the start process. It all went very smoothly.

Tomorrow we will continue with the 80m and 2m classic events.

Here are my pictures from today, if you also took some please send them to me either as an attachment or in an album and I’ll add them to this location.
