Any other speculation as to who will compete, I imagine they will play as pairs rather than individuals like the race.
I'm imagining:
Cowboys, Globetrotters, Tyler & Korey, Adam & Bethany, Dave & Connor, Tiffany & Krista,
Hoping for:
Charla & Mirna, Ron & Christina, Dustin & Kandice, Rachel & Brendon (probably on BB version), Team Guido
