Note
I liked the race format: a rafting section on the Lehigh River, some biking, some river crossing with bikes and tow lines, more biking, a run up a huge hill and back down, more biking and then more biking (a combination of single track, canal towpath, huge uphills and downs, and some road) eventually ending up at Hickory Run where they had 4 controls on the land adjacent to the O map and 17 controls that I set on the O map. These last 21 controls were rogaine format - get as many as you can before the 24 hour time limit. The race started at 3:30 pm and teams starting coming through for the O section around 1am. Three teams got all the points. Some teams got a handful and called it quites at 11am, other teams got as many as they could right up to the 3:30 cut off. The nice thing about the format is that the top teams don't finish and then 6 hours later other teams are still straggling in. Here the top teams were finishing around 1pm right along with other teams that had decided they'd had enough. But unless you got them all you didn't know how you did until everyone was in so most of the teams stuck around until the very end.
Note
They had an interesting way to make sure all team members visit controls. At a few controls, there were bags of nail polish with instructions on which fingernail on which hand was to be painted. There were different colors at different controls and everyone on the team had to paint the designated nail. At the finish there was a check that everyone had red, white and blue nails on their left hand. (There was a Fourth of July theme - the race is called the Cradle of Liberty AR.) It wasn't announced which controls were going to have the nail polish - the boulder field was the only orienteering control that did - so if not everyone went to the control you risked having to go back for your team mate and back to the control.
