(Tony's brother Dave, Dave's wife Andrea, & Tony & Dave's mother Anna)
Tony hit 29 km at 10:58, and took his break, so that's where he was at 4 p.m. His swimming is still steady, but he's having some problems emptying in the bathroom, so he's "lost" a bit of time there. Still looking good. He's done 69% of the distance; 13.2 km left.
He's 23 minutes & 1 km ahead of his plan. Because he planned his last "hard" hour (3 km) for 4 p.m. I expect he'll converge back on his original plan. Rhonda & Anna, who know him better than me, are still confident in his doing the whole thing.
