Speed Training

Initially I wanted to start my training only in March but it has been brought forward a couple weeks. My boss just asked a few of us to participate in a company organised 7km run. It seems like he wants to try to win the team event of the fastest 6 finishers. I guess I need to start training for some speed as the race is end March. The chosen runners have decided that all we need to do is to beat the boss in the race so that we wouldn't be blamed for losing the race. I guess it is down to doing intervals for the next few weeks.
