The rainy weather also prevented hundreds of Special Olympics athletes from competing in the State Summer Games in Stevens Point.
Athletes and families stayed indoors at UW-Stevens Point for most of the day to keep from getting soaked.
Swimming was also pushed back a half-hour, because of thunderstorms.
All of the games canceled today will take place tomorrow.
A spokeswoman says it's not putting a damper on the number of people showing up this year.
"We have about 2,000 athletes that come out to our state summer games every year about 900 coaches and 3,000 spectators so its our biggest event of the year actually," Christina Harris, Special Olympics Spokeswoman.
The athletes are competing in four summer games.
They are track and field, soccer, swimming and power lifting.
