ESPN Unified Challenge!


Underdog and FunCorp are excited to team up with the Special Olympics and ESPN to raise money for the athletes competing at the 2018 USA Games this Summer in Seattle!


Teams of 4 will join together with a Special Olympics athlete and a law enforcement officer to create a unified team of six people. Each team will participate in six activities, with top teams advancing to the playoffs and a champion crowned! 


Recruit your co-workers or friends and sign up to support some fellow athletes from Special Olympics USA as they visit Seattle for the first time!

Convert your Office Space into a Fun Center

Need to throw a party at the office?


With our Conference Room Olympiad, FunCorp will convert your existing conference room, parking lot, or open work space into a customized Friend-Building Party!


Our "Parties with a Purpose" will create memories, such as the time you sank a hole-in-one, hit the bullseye in Soccer Darts, or most important that moment you gave your co-worker a high five as you got to know them a little better.


Who says work can't be productive AND fun??

 Registration for Red Rubber Showdown 2018 is now OPEN!

Signing Up As An Individual?

Signing Up As An Individual?

Here's what you need to know!

Underdog is a great way to meet new people if you've just moved to town or are looking for something new to do. When you register as an Indivdual or "Indy" your name is put on a list and when enough people register we make an "Individual Team" and introduce you to a whole group of new people.


Have another friend or two who want to play with you as well?  No problem.  In your signup there will be a spot to enter their name(s) so that we can place you all on the same Individual Team. Also, be on the lookout for our Indy Parties - another great way to meet and socialize with people!


Check out our Indy Rundown Page for more info and upcoming leagues!
