There is so much data, sometimes it can be a bit overwhelming! So let’s break things down a little and get you started.

What we’re all interested in… Lets look at a forecast!
Here’s an example forecast Friday 12th November 2021 -10am. Find out how to load a route into myWindsock here.

Finding Key Moments
The Course Navigator highlights areas of interest on the course, including headwind, climbs, and Strava segments. Also found in the Navigator menus are any intervals you have created.


Setting up your Virtual Rider
The Virtual Rider, rides the course for you. You simply specify what the parameters are that the VR adheres to.

Unit Preferences
If you’d rather have miles rather than kilometers or perhaps Farenheit instead of Celsius. It’s easy to make this change from your account page.
Go to the Account Page and change unit settings.
Unit options
Speed
- KM/H (Kilometers per hour)
- MPH(Miles per hour)
Wind Speed
- M/S (Metres per second)
- MPH (Miles per hour)
- KM/H (Kilometers per hour)

Creating a Ride Plan
The most powerful chart… ever!
The Last Change Delta sounds dull but it really unlocks alot of the analysis. We’ll demo this chart with two ‘go to’ experiments.
Exp 1. Biggest bang per Watt
First of all let’s see what impact reducing power by a relatively small amount, 5 Watts, has on our time. This experiment works by increasing power too. Only make a small change for best results.

Our Virtual Rider lost 29 Seconds, but it won’t be lost evenly across the course. What we really need to know is where on the course we lost the most time. If we know that, we can ensure we prioritise our power in those places. Additionally, we may find some free rest time… handy hey!
So lets look at the Last Change Delta Chart…

We can also see there are a few sections that plateau, the line becomes almost flat, meaning that the decrease in power output doesn’t actually have a massive effect. So if you need a place where you can ease off the power and recharge your batteries, this is where you can do this without a major impact on your overall time!
Exp 2. Where aero matters most
Let’s repeat with a similar test. This time we will discover where a positive change in aerodynamics will have the greatest impact. CdA is your efficiency at moving through the air. Learn more about it here.
This time we’ve reduced the Virtual Rider’s CdA by 0.005.

The dotted line shows the average change in time. Where the green line starts lowering at a steeper gradient than the dotted line, this means we are going quicker than the average time gain, so we should preference these points for aero.
Where the green line plateaus out, or starts levelling out at a lower gradient than the dotted line, it means we are gaining time at a lower than average rate. In these areas, we could relax our position a little in preference for power production.
Putting our findings together with Intervals
Now that we’ve made some observations, let’s form a plan. Creating an Interval breaks the Virtual Rider from it’s profile settings for the selected period. Find out how to Create Intervals here.
I like to create two identical Virtual Riders, a ‘Baseline’ Virtual Rider and a ‘Test’ Virtual Rider. The ‘Test’ rider will have intervals applied to it, we can then view the impact of our intervals vs the baseline.
We’ll add an interval to one of the climbs. Looking at our Last Change Delta above, this is where deviating from the overall plan will have the greatest impact on your time.

Remember you can find the Intervals you have created in the Navigator menu in the top bar.

Now that we’ve had a look at how to experiment with some of the data, lets have a look at some visualisation techniques to help prepare for the days conditions.
Wind impact
For us, the best way to manage the headwinds, is to visualise it as we would a hill. Here, we show how the wind can change our perception of a flat or inclined surface.

See how the wind will reduce the slope of the actual elevation. However, the flat middle section would feel a little up hill.
Also from the chart menu, check out the Feels Like Gradient chart.
There is more about Feels Like Elevation here.
