Within the unending quest to present runners extra information (and extra causes to improve and spend extra on their watches), watch firms are squeezing each bit of knowledge they’ll consider into their watches.

Floor contact time, restoration charges, VO2 max, race predictions, and extra.

The unlucky half is, not solely are most of those measurements ineffective (as a result of they depend on imprecise formulation or information measurements), however they’ll really be an enormous detriment to your coaching.

Let me present you an instance from my VOmax measurement.

At first look that is pleasing to the attention.

I’d say “LOOK! I’m within the purple, the very best tier on the watch”. Let me bask on this health.

You may even assume I’d be joyful.

However, then I see this:


Hmm..

That appears fishy. Let me clarify.

5k: 14:37
10k: 29:39
Half: 1:06:17
Marathon: 2:16:59

In school, I participated in a analysis research inside our kinesiology program. As a part of the research, a number of athletes and I have been requested to carry out a lab-driven, VO2max take a look at.

My outcome: 84.5ml/kg/min.

After my take a look at, the researcher paused and instructed his colleagues to recollect today as a result of they might by no means see a better VO2max.

I received’t mislead you, this was gasoline to my delight. I paraded that piece of paper round like Charlie Bucket.

My teammate, who additionally participated within the research, scored 72 ml/kg/min. Based mostly on the appreciable distinction in our take a look at scores, you’ll assume my larger VO2max would equal a higher efficiency. Nonetheless, my teammate beat me in each single race that 12 months.

Why is that this?

I had a superhuman VO2max. I ought to have left him within the mud. But, not solely did I lose to him, however I commonly discovered myself mid-pack of most races.

Whereas on paper my VO2max is extraordinary, I used to be very a lot an peculiar collegiate athlete.

How may I, with a VO2max larger than among the biggest athletes of all time, not compete as one?

You’ve heard of the phrase “in case you don’t use it you’ll lose it” proper?

I may give you no higher instance of the serial marathoner trying to race a 5k.

No energy, no turnover, NO FUN.

We are able to keep away from this although, and we are able to achieve this whereas not solely enhancing energy and leg velocity, but in addition enhancing our marathon instances too.

Now, this pertains to all occasions. Not simply the marathoners!

To makes issues simpler, I’ve even taken the time that can assist you take this one step additional.
