Run123

Select the Run123 app.

Press "Load" tab. Select Demo1 which is a simple test of positions. The checkmark shows that ride is loaded.

Press "Map" tab to show the geographical points of the ride data. This was recorded on a bicycle path.

Press "Sensors" tab to show ground speed and other recorded data.

Press "PreRun123" tab, then "Scissors" to create categorized runs from the FIT data.

Runs are created and categorized based on their velocities and GPS coordinates.

If a run is incorrectly categorized, swipe and recategorize the run.

Press the "Mappoint" icon to view the run paths. The green dot marks the start, and the red dot marks the end. Check the categorization so that starting and ending points are consistent.

If a run is incorrectly categorized, swipe and recategorize the run.

Press "Run123" tab. Initially this shows all available selected runs.

Click a run to hide/show it. All currently selected runs are shown in the lower graph.

Hide all runs which have "issues" ie weird velocities. For example hide the runs where the rider is still pedaling and accelerating inside the test section.

You need to select at least 1 Fast Downhill, 1 Slow Downhill, and 1 Slow Uphill run. You can select more runs for each category.

For convenience you can select demo runs from the right-most menu item.

Select the DemoA 112. This consists of 1 Fast Downhill, 1 Slow Downhill, and 2 Slow Uphill runs.

Use the default solver options for vector CdA and scalar Crr. Options can be set using the "Cog" icon.

Click "Calc" to see the Run123 solution for your selected runs.

The mean and standard deviation for the aero drag coefficient CdA, rolling resistance Crr and elevation H are listed and graphed.

The CdAs are very close to each other -- indicating similar position for all runs -- well done!.

Here there are 2 datapoints plotted since there were 1*1*2=2 combinations.

Press "<" to return to Run123.

Click some rows to add additional runs.

For convenience you can press "DemoAB 212" to select 2 Fast Downhill, 1 Slow Downhill, and 2 Slow Uphill runs.

Click "Calc" to see the Run123 solution for the selected runs.

The CdA row shows that 4 CdA values were calculated.

There are now 2 clusters of datapoints, indicating that the 2nd Fast Downhill had worse CdA then the 1st.

If you select nFD Fast Downhill, nSD Slow Downhill, and nSU Slow Uphill runs, then there are nFD*nSD*nSU combinations. The solver calculates solutions and variances for each combination. So picking a few similar runs can generate many datapoints and helps to improve the precision of the solution, and improves the solved values for *all* runs.

Run123 also enables you to easily compare rolling resistance AB configurations.

The Crr row shows that 4 Crr values were calculated. The solver reports a sigma of about 0.00006 which is quite precise.

The FIT demo contains several AB tests. Selecting two or more Fast Downhill runs using the same "A configuration" is an "AA" CdA test that lets you either see how consistent your baseline CdA is.

Selecting a Fast Downhill from "A configuration" and a second Fast Downhill from a "B configuration" lets you see the results of the AB test.

For convenience you can press "DemoAB 233" to select 2+3+3=8 runs, resulting in 2*3*3=18 combinations.

Note that all the Fast Downhill runs look similar to each other, the Slow Downhill runs look similar to each other, and the Slow Uphill runs look similar to each other. This indicates that the CdA & Crr for each category are similar, so we can expect good results from analyzing these runs.

Run123 enables you to easily compare aero drag AB configurations.

The CdA row shows that 18 CdA values were calculated. Note that several CdA values are so close that they cannot be distinguished in the graph.

Here we see 18 datapoints in 2 clusters (9 in each cluster). The 2nd Fast Downill was clearly worse than the 1st.

The 3-sigma CdA variation within a cluster is about 0.005, indicating that sigma~0.002. This is typical for a recreational rider. Pros can get even tighter clusters (lower sigma) since they can maintain a single position better.

Click the "Report" tab to show all report items that were created when you pressed the "Camera" icon on previous pages.

Change the order of report items as desired.

Edit each report item with markdown text.

Press the PDF icon to generate a PDF report.

Each report item has markdown template text. Press "Eye" to see what the formatted markdown text looks like. Press "Check" to save the edits.
