ganabathi: If I'm correct, my guess is that you be joining the FTAAA cross country race? Since it's only 2 weeks from now, my suggestion on what you can do is, go out on a hard and fast 5K run on this remaining few days of the week till say Saturday. But please watch yourself. Don't over do it. Next week, starting from Monday start from a 10K easy run running down to a 5K on Friday. This will allow your body to "temporary instantly" adjust to race conditions while recovering at the same time. I hope this will allow you an instant boost for the race in 2 weeks. Good luck.
