Since that list of names means nothing to me without context, here's photos of the teams...
This is much better than the original rumour that the entire race was just going to be former Big Brother people.
It's nice to see they went far into their own past to get Colin & Christie. I believe they were invited to participate in the original All Star Race season but they were unable to do it because she was near the end of a pregnancy.
TAR #5 with Colin & Christie was the first Race I watched (also, the first and - so far - only time TAR has had a real leg in Canada, when they came to Calgary). It was shot almost 15 years ago. I wonder if time has mellowed Colin much? They were definitely one of the strongest teams to not win their Race. IIRC, at one point, they were more than a full day ahead of all the other teams, but a bunch of "Hours of Operation" and travel bottlenecks allowed the pack to catch up to them.
The show ultimately made some significant rule and structural changes after Colin & Christie's first season because of how strong they and the other final 3 teams were. They introduced the rule requiring each team member to do a minimum number of roadblocks during the race (Christie only did 1 the entire race) and they started to tweak the travel and schedules to ensure that no team can really pull ahead of the pack from leg to leg anymore.
