How to use Run123 to calculate (CdA,Crr)
The Run123 web-app analyzes a Notio JSON file. Run123 lets you inspect the sensor data, calculated (CdA,Crr), and validate the answer by comparing Measured with Virtual values.
The app has 8 primary pages: Info, User, Load, Map, Sensors, CdA, Validation, & Report. You start at the User page and work your way down.
Info describes why the app was created, this short how-to, a FAQ, further reading if you are interested in bike aerodynamics, ... and more.
User lets you register, login and manage your subscription. After registering you can run (free) demos, while other features are subscription-only. Computing the Run123 (CdA,Crr) analysis for your rides requires a subscription.
Load lets you load a demo file or load your own Notio or FIT ride. Loading demo files is free.
Run123 categorizes runs in a single file into Fast Downhill, Slow Downhill, and Slow Uphill runs. Run123 Options lets you control the solver settings for CdA testing or Crr testing.
Ride shows you info recorded in the Notio or FIT file, including total weight, assumed Crr, ANT+ sensors etc.
Map shows you a map of the loaded ride.
Sensors lets you graph any data value, but defaults to showing the computed Run123 ground speed.
Pre-Run123 automatically categorizes your data into Fast Downhill, Slow Downhill, and Slow Uphill runs. You can simply swipe left to manually override the category for any run.
Run123 lets you select which Fast Downhill, Slow Downhill, and Slow Uphill runs to analyze. You need at least 3 runs. View the speeds of the selected runs, then Calc to solve for the desired CdA and Crr.
Validation graphs the Virtual values (e.g. virtual elevation) and the corresponding measured values. The virtual values are computed without using the measured value. The computed values are accurate if and only if the graphs are similar.
You can learn more about Virtual Elevation that Robert Chung has popularized in Info>LearnMore.
Report shows a list of report items (screenshots and text). You add a report item by pressing the 'Camera' button on other pages. Selecting a report item lets you add html-formatted text to the item. Press < to cancel or checkmark to accept. Swipe left to delete an item. Press the 'PDF' button to create a PDF report of the report items.
