1000 Step-ups (or as many as you can do in 35 min)*If you have a ruck or weight vest, feel free to wear it. On December 14, 2018, CrossFit Games Director, Dave Castro posted this workout in memory of Wilkinson, who was a friend. Castro said, “A few weeks ago we lost an American hero. A friend of mine and someone I worked with when I was in the Navy. At his funeral his wife mentioned that he did 1,000 step ups for time with a 45 pound pack on a 20” box to train for climbing Mt Aconcagua."
