Coach Conversations: Allen Lim and Metrics

Coach Conversations: Allen Lim and Metrics

There are a lot of algorithms and methods out in the world that can take your basic pattern of power output during a ride and use some fancy math to boil it down to other numbers. Power training expert Allen Lim prefers to keep things simple – like Occam's Razor simple. Occam's razor states that all things being equal, the simplest solution is the right one. For Allen, accuracy from a cycling power meter is everything.

  • Don't over complicate the metrics. According to Allen, you and your power coach can do a lot more with one accurate number than a bunch of other metrics that maybe aren't as on point.
  • Use metrics to understand the distribution of training zones and/or peak powers to help an athlete train properly.
  • The real value in using power output as a training tool is not the daily information, but the chronic, long-term data.
