Basically, yes. And they'll let one or two groups win. How many episodes are left?
Just in the last episode.... we hear the runners were "totally off the grid", then the next thing you know, they get some real time "tip" or "clue" (the tranny license plate, the bank transaction). Walah, within minutes the hunters are in the correct mall parking lot because it's "lunch time". Walah, they are in the exact camping section they need to be in even though they say it's a massive area of undeveloped land. Those dudes are done in the first segment next week. It's not like 5 or 6 days passed after they got their info. They're always right where they need to be.
There have been 2 British versions of this show. The first season, 2 teams out of 6 evaded capture. The next season, 1 team out of 5 evaded. From the wiki:
