Tour de Tuscaloosa Power Data

March 26, 2012 at 7:28 pm 5 comments

First, before the power data – here’s a video that my wife got of the Pro/1/2 criterium finish Saturday night where I got 5th in the race, 4th in the field sprint.

And now for the data – first the summary data, splits, and HR/Power graph for the criterium and the road race.

Now for the detailed data graphs and plots … first the critical power curves for both the criterium and the road race. I tied one power record in the criterium, and I set three new personal power records for the road race as indicated on the graphs.

Here are the pedal force / pedal velocity graphs which highlight the different amount of force being applied to the pedals at different cadences.

And finally here are the power maps for the two courses:

    I’m kind of surprised that your 25 minute power is 307 watts, is that just a function of the fact that you rarely ever do a long sustained effort?

      Yes, most of my power meter data the critical power curve is based upon is coming from road races and criteriums where I am trying to use as little power as possible. So you just get a bunch of bursts of power of various durations which explains the reverse exponential at the beginning of the CP curve. I’m pretty sure I could maintain at least 325 watts for 30 minutes under the right conditions.

    ahhh i gotcha…that makes sense! i was thinking that you put all of your rides on there instead of just races. I’d be curious as to what you could do for a 30′ TT…mainly so i could compare it to mine :)

    I am guessing xPow is normalized power, yes?

Short very hot ride. Cahaba river at the lowest I've ever seen it - at Hoover east ballfields shortly before running over fresh gum and cutting the ride short to clean it off my tire. Today's rollercoaster experiment - 20 repeats with Garmin 1000 forwards and backwards. Movie theater roller coaster (top) and Green valley rollercoaster (bottom).

Quick reference stats

Anaerobic Threshold:
Power:315 watts
Heart rate:180 bpm
Maximums:
Power:1097 watts (5s)
Heart rate:198 bpm (5s)
AT power estimated by critical power curve in Golden Cheetah, which predicts I should be able to maintain 315 watts for 1 hour.
