I have an unhealthy relationship with McMillan’s Running Calculator. Some might call it obsession…
I recently posted about McMillan’s “equivalent performance” here.
I plugged in my latest marathon time of 4:26:02 to see what McMillan had to say.
Half Marathon prediction: 2:06:08
Actual Half Marathon: 1:52:29
10K Prediction: 56:41
Actual 10K: 47:59
5K Prediction: 27:19
Actual 5K: 22:36
So what does this mean? Do I just suck at marathons? (Kidding!) Do my strengths lie in shorter distances? Do I simply need more experience? Is it all mental?
Based on my 5K time, McMillan claims I could run a 3:40:19 marathon.
Based on my 10K time, McMillan claims I could run a 3:45:11 marathon.
Based on my half marathon time, McMillan claims I could run a 3:57:14 marathon.
With the right training and a good day, am I capable of achieving those times?
Who knows. I am well aware the McMillan is only a guideline. But with the numbers being so far off, I definitely feel a bit stumped.
Maybe I should just stop thinking about the numbers for a while…
