The Amazing Race Preview for 'This is Where it Ends'

Season finale of The Amazing Race tonight as four teams are left.

The race will finish up in Miami after the teams go through Brazil.

The winner will be the first team in Amazing Race history to win after experiencing the taste of defeat in a previous season. This has been called an "all-star" season -inviting past contestants back to race one more time, but no winners. That guarantees a happy end to tonight's race, no matter who wins.

Looking at finishes through the race so far, best friends Zev/ Justin have finished 1^st in 4 of the legs. Father/ daughter team Gary & Mallory have finished 1^st in 2 legs as have basketball team mates Flight Time/ Big Easy. Sisters Kisha/ Jen’s best finish has been 2^nd place.

Tune in to CBS Sunday night at 8PM ET/PT to watch the Season Finale of The Amazing Race Unfinished Business to see who won and will hear host, Phil Keoghan declare them winners of the $1,000,000 prize at the final pit stop and earn Redemption in this season of do-overs
