The 2012 Adrenaline Challenge is taking place this weekend and we’ve got superb photos from the tournament. The 11th annual Adrenaline Challenge, after two days of competition, the crown for Best of the West will be claimed. Over 100 teams have converged in San Diego to take part in what has become the premier team tournament in the West and one of the top team events across the country. For the second year in a row, the Del Mar Polo Fields opened up its 50+ acre property for the fast paced and action packed weekend across 17 fields. The games showcase players from all age groups. Our friends from South Swell Sports snapped some images for us. View them below.
