A fellow rider saw the accident and reported that he was looking like he was about to pull ahead, then turned around to see how far back the trailing group of about 20 were. He then either caught the wall with the h-bar or pedal, nobody knows and he was subsequantly launched across the road, landing on his face. Massive injuries to front of head.
He was a terrific competitor and died doing what he loved best.
RIP.
