I like watching runners. (I gave up running quite some time ago when it started to make my knees hurt.) There seemed to be a lot of running going on this weekend.
Madison Chicago 200 Relay in which teams of 12 people took turns to run 200 miles (322 km). They started the teams according to expected times which varied by up to 10 hours. The slowest teams started first so that teams would finish at about the same time in Chicago. (Some of the runners we saw in the morning didn't look like super athletes. I really liked the spirit of the relay that it encourages people to try something so impressive and with the emphasis on having fun. The relay generates funds to support the Special Olympics of Wisconsin and Illinois.) Each runner had to run 3 segments totaling between 11 and 21 miles during the 36 hour long event. They limit the race to 250 teams (3000 people)! We biked past the starting point so we stopped and talked to some participants who were waiting their turn to start.
