2014 USA Pro Challenge Power Analysis

The 2014 USA Pro Challenge takes riders across the state of Colorado over seven amazing stages. Featuring high altitude, big climbs and fast racing, it is one of the top races on the calendar. Take a look at the power these top athletes produce during this tough week of racing.

Stage 1 –  Aspen Circuit Race – 61 Miles Michael Rogers (Team Tinkoff Saxo)


View Rogers’ full file here.

  • The first stage was short, only 61 miles, but it wasn’t easy. Rogers put out a Normalized Power® of 285 watts for nearly three and a half hours.
  • At over 6,500 ft. of altitude to start, the altitude will supress both heart rate and power output. We see that Rogers average heart rate was only 149 for this stage.
  • Like we saw during the Tour de France, Rogers prefers a bit lower of a cadence, averaging 82 rpm.

Stage 2 – Aspen to Crested Butte – 105 miles
