3km or 5km?

I left office before 6pm. SMS Slow_Runner that I will try to run 3km or 5km if not raining.

Not sure why, but I decided to go for 5km and then, another 1km to make it 6km. I completed the 6km in exactly 42 mins. Not fast but not slow either.
Hope I can survive the 3km x 2 Banana Relay @ East Coast on this Saturday morning. My 2nd Right toe is aching and my Left big toe is a bit pain. At least IMD clarify that can either walk/run/crawl and no need to worry about completion time.
