Will it be worth $1200 to you to double your mileage this year and achieve the goal? Cost obviously varies with the number of days needed for success. Would it cost you more or less to fail this year and achieve it next year? That is one way to look at it, if you believe your time has a value.
I don't think that really works.
My time doesn't have a dollar value so much as what I do with it. Someone might pay me to mow their lawn. They probably aren't going to pay me to watch my television.
His choice is to either take those vacation days or ride his bike and forfeit it. It makes no difference to his income either way unless he was going to spend his vacation mowing lawns.
