All time low

The last two weeks had been really hectic(procrastination is a tough task master) as I had to work (some one said meticulous work ethic is the best..hmmph) towards getting tangible results for the evaluation which I had on the first of this month. And who said debugging was an easy job; just when you thought everything was fine and dandy, you suddenly realise that the program isn't compatible(for some strange reason) when you have a c source code and c++ header files. Anyway, I somehow managed to get it working in the nick of time.
I always thought (at least during the last two years) that "I could run 10 laps (4 kms) in the stadium any day, even if I hadn't run for more than 3 weeks". But today I discovered the amount of truth in that assertion when I barely managed 5 laps. My legs felt really weak during the run as if all the calf-muscles had been wasted (atrophy).
My fitness now is at an all-time low, but the good news is that the final evaluation isn't due till april end, so I might get a good amount of time to work on regularising my runs.
