Ride it out
There’s a moment at the end of a swim lap that you have to decide between stretching out and riding out your inertia — or doing one last stroke to reach the wall.
Of course there are different personalities: some prefer to hit the wall at full force, others do a final all out push just before the wall to glide into the finish.
A similar dynamic can also happen on projects. Some push their teams until a few hours (minutes?) before the deadline. I usually end up with a hard week and working weekend on the final stretch, but on the final days I let the team inertia set the pace.
