The plan was simple: if Klaus's team made it to Alpha first, all of them would enter and continue to a point they had selected on the map. He, on the other hand, would stay behind and thin down the number of their competitors.
The second part of the plan was that if they weren't the first to arrive, they would select their strongest members to fight while the weaker links tried to enter. It was the best strategy they could devise, knowing that the other regions would do whatever it took to stop Klaus's team.
Klaus knew that with 100 people traveling with them, he and his friends couldn't run off as they pleased. They would have to function as a team, and so, as a cohesive unit, they moved at a pace that everyone could benefit from.
