I had my VO2 max tested a couple of weeks ago and the result, 61.5, suggests that I’m in the “fit amateur” category, which is what I already knew. Most elite athletes fall into the 70 to 90 range.
But then I checked out an online calculator that claims to predict race times based on VO2 max and found out that my 61.5 means I should be able to run a marathon in 2:39.
2:39!
That is 13 minutes faster than my personal best performance after running 6 marathons and achieving what I thought was my peak.
That number got me all fired up about running again. I will train harder! I will run more! I will enter more marathons! Heck, there are some backwater races out there that I could win with a time like that! Bring on the trophies and shwag.
Then I talked to a coach who dampened my enthusiasm. He questioned the validity of my VO2 test, for one, and suggested that the online race time calculator was, well, bunk.
There are lots of things that determine race performance, like lactate threshold, and VO2 max alone doesn’t tell you much by itself. He said some people can run more efficiently than others at a given VO2, citing famous marathoner Frank Shorter who had a relatively low VO2 for an elite athlete but was incredibly efficient and able to run for a long time at a extraordinarily high percentage of his VO2 max.
The coach said if you want to run faster, this is what you’ve got to do:
1. Hire a coach and get on the right program.
2. Isolate variables so that you can measure your progress (such as running a set route under identical conditions and a set heart rate a couple times a month) and focus on improving your efficiency.
Those are two things I’ve never done in an organized way. So I may not go out and push myself to run a 2:39 marathon, but I know there are some things I can do to improve my running. Plus, thinking about this has got me fired up about the 2010 running season and building my distance so I can run 50 km days on the Bruce – even if takes me longer than the 3 hours 11 minutes that the online calculator predicts ( Ha!).
