A spirited fight can be good, but please don't burn yourselves out. Much like when running, people generally prefer the pace they set themselves, but when someone comes up from behind they can incite a competitive burst. Next thing you know you're both giving it your all, more is getting done and at a faster pace, but at the same time you're giving up more of yourself for your hobby. It puts a toll on you, and if you don't have the foundation it can lead to you losing interest in the action.
Be careful, whatever you do. It is in the reader's interest that things continue, so we will always selfishly ask for that, but deep down we know that it's not the same for the scanslators.
