Last year at this time we had our first endurance HoH competition of the season with the giant brick wall. The result of that week was Casey went home. Both events could happen again this week and being it has been a week of Deja vue with Jesse and HoH and the Brains on slop, I'd say it might all just happen again.
Today the HGs were given special tennis shoes for Thursday's competition. The house guests feel like this is so that they all have the same 'equiptment' and no one has a competitive advantage in whatever the Head of Household competition involves.
Being as they got shoes it would suggest standing or walking/running more than hanging, the latter of which would have been an advantage for lighter, smaller females (Natali and Chima?). Hard to say who would have an advantage in a running/walking competition. Casey actually seemed to spend the most time on the eliptical, followed by Russel.
It should be interesting to watch and remember that since Big Brother After Dark started - most endurance competitions have not lasted until the show kicks in at midnight eastern - so the only way to see the finish will be via the Live Feeds.
