How Accurate is Strava for Mountain Biking?
Have you ever wondered just how accurate Strava is when it comes to recording your mountain biking activities?
Well, you’re not alone. Many mountain bikers question the accuracy of Strava and whether it truly reflects their performance on the trails.
Strava’s accuracy varies depending on the device used, with dedicated GPS devices generally being more accurate than phones. Strava is a tool for tracking and comparing rides rather than a precise measurement of performance. It is best used consistently with the same device, and personal performance comparisons are more reliable than comparing with others.
In this article, we’ll delve into the accuracy of Strava for mountain biking and explore the factors that can affect its reliability.
So, if you’re curious about how reliable Strava is for measuring your mountain biking achievements, keep reading to find out more.
Accuracy of Strava for Mountain Biking
Strava is a popular choice for tracking rides and analyzing performance. But how accurate is Strava for mountain biking?
Based on our experience and fellow mountain bikers’ report, here are some things you need to keep in mind regarding Strava’s accuracy:
While Strava may not be accurate enough for serious racing, it can still be a valuable training tool when consistently used with the same device.
Factors Affecting Strava’s Accuracy
Strava calculates segment times by drawing virtual start and finish lines on specific segments of a trail or route. When you pass these points, your time is automatically recorded and compared to other riders’ times in the same segment.
This allows you to compete against others and track your progress over time. Similarly, Strava calculates average speeds by dividing the total distance traveled by the total duration of the ride.
Here are some factors that can affect these measurements:
It’s important to note that the leaderboard can be dominated by people with less accurate GPS devices, and start/finish sections near loitering points can result in incorrect times.
Comparing your own performance on Strava can be reliable, but comparing with others should be seen as a fun aspect rather than a definitive measure of ability.
It’s worth noting that some users may exaggerate Strava’s inaccuracy when they believe they’re faster than they actually are, while others may achieve seemingly impossible segment times.
Is There a Way to Get Better Accuracy on Strava?
Yes, there are several ways to improve accuracy on Strava:
Devices Compatibility with Strava
Based on our experiments, Strava integration with Garmin watches has generally been smooth, as long as segments aren’t shortcutted.
The Garmin Fenix watches, including the Fenix 7 series, are known for their reliable GPS tracking on MTB trails deep in the forest.
However, many MTB riders trust the Fenix watches on Strava for tracking segment times.
We recommend comparing the watch’s measurements with trail data from platforms like Trailforks.
Maintaining the same line on an MTB trail for comparison can be challenging. Variables like tire pressure, suspension settings, rider weight, and kit weight can affect a bike computer’s accuracy on MTB rides.
Using Power Meters with Strava
According to a post on the Strava Community Hub, the Strava mobile app does not currently support direct connections to power meters or cadence sensors.
However, you can still use power meters with Strava by connecting them to a head unit or cycling computer and then syncing the data to Strava.
Once you’ve connected your power meter to a compatible device and synced your ride data to Strava, you can view a variety of power-related metrics on the app, including average power, normalized power, and power curve.
Strava’s Estimated Power Inaccuracy
When I recently visited Austin, I decided to leave my power meter pedals at home and use a regular set on the rental bike instead.
As an experienced rider with a power meter, I know what numbers I can achieve and how different power levels feel. However, Strava’s estimated power data for my ride was way off the mark.
According to their calculations, I supposedly averaged 327 watts over a three-hour ride, which is wildly inaccurate.
In reality, I would estimate it to be around 165 watts. Even my PR on a segment was exaggerated, with Strava claiming I achieved 432 watts for over 15 minutes.
The reason for such discrepancies is that Strava doesn’t account for factors like aerodynamics, road conditions, wind, drafting, and countless other variables that affect power output.
While the estimates can be somewhat close on certain climbs, they are not reliable for training purposes.
If you’re serious about training with power, invest in a power meter rather than relying on Strava’s estimates.
Ride for fun, not for Leaderboard!
Mountain biking is all about the pure joy of riding for fun. It’s about exploring trails, feeling the exhilarating rush of adrenaline, and immersing ourselves in the beauty of the great outdoors.
In today’s digital age, the focus seems to have shifted towards virtual trophies and chasing segment-based goals, like becoming the King or Queen of the Mountain (KOM/QOM).
However, we mustn’t forget that mountain biking is not just about numbers and statistics; it’s about the incredible experience, the deep connection with nature, and the electrifying thrill of the ride.
Let’s prioritize the sheer enjoyment of riding, relishing the trails, and creating unforgettable memories rather than becoming consumed by the pursuit of virtual recognition.
