The post-marathon mystery 5lbs. are gone, yet at 125 I'm at what feels like a "heavy" training weight. I suppose it's time to start whittling the weight down now so I can arrive at 115 racing weight in April.
Ever wonder how much those few extra pounds slows you down? There's a simple formula you can use to calculate a projected V02 Max based on a projected weight loss. Simply multiply your current weight by your current V02 Max, then divide the result by your projected weight.
For example, I currently weigh in at 125 lbs., and based on my most recent 5K and 10K race times at that weight my current V02 Max is around 40.8. If I wanted to see what my projected V02 Max would be if I were to lose 10 lbs, here's the formula...
125*40.8/115 = 44.3
As you can see, if I drop 10 lbs my V02 Max would go up over three points! A 5k time at V02 Max 40.8 is 23:42,while at V02 Max 44.3 it's 22:05. That's a pretty significant improvement for simply losing 10 lbs.
Now that's motivation!
P.S. The link below will calculate your V02 Max based on a race time.
