Did the Assateague century with 3 other guys from my team. We were aiming for sub 5 hr riding time and did it in 4 hr 50 min, just under 6 hr total. From the start to the first rest stop was crazy, we were just starting to settle in a tempo of about 22 mph after the crowd got thin enough, when there is a guy that passes us on a tt bike. So we decide to follow him and see what happens, turns out he just kept on going 26 mph with the 4 of us barely hanging on behind. He told me he was training for a iron man! If he kept that up that would be a pro pace. At the first rest stop we bailed out to get some food. After that we actually had to take turns pulling and the pace dropped to about 24 and then when the adrenaline rush settled down we dropped further down.
Had tons of fun, so many people, lots to watch. Lots of inexperienced people also, 2 of them would occupy a full driving lane and it seems like we spent half the time on the wrong side of the rode.

About 2/3 of the way my team mate's bike was making a strange noise, so we stopped and it was his carbon frame that was cracked. He rode on thinking that he would have to replace the frame anyway, but at the next stop the people from bike dr told him that it could still be repaired if he didn't make it worse so he waited for the sag car to take him back. Later I was left with only 1 other team mate when the fastest of us 4 went ahead as we had agreed the last section was a free for all. As our pace dropped to 20/22 we also started to get other people hop on to our "train". We managed to up the pace 1 more time by joining a large group of experienced riders that were doing a double pace line. But after the last stop our pace was barely above 20 and we also got a pull from a tandem, a guy with what seemed to be his girlfriend at the back, he told us that he was just soft peddling at 20 mph with headwind. It sure helps to have double the power without double the drag!
