Hidden locations

31 May, 2012 by David Johnstone

If somebody looks at the GPS data from a ride you did, they’ll be able to see exactly where you started and finished, and that will often be where you live. So, in the name of privacy, you can now provide addresses and no GPS points will be shown that are near that address.

Users can go to the privacy settings page (it’s one of the pages under Account) and add whatever locations they wish to hide. GPS points are only hidden from other users, so don’t worry if you go to one of your rides and can see points that should be hidden. If you want to make sure it’s working, copy the URL of a ride and go to it after you log out (you can also share rides with others by sharing the URL).

One known issue with this is that if you go for a ride entirely in a hidden area (like what you might do on a trainer), the map of the ride will show an area off the coast of Africa (where the latitude and longitude are 0). This will be fixed soon when this learns how to deal with rides on trainers better.

This is the first of a series of features to make sharing rides better. Automatic sharing… continue reading

Improved power curve

31 May, 2012 by David Johnstone

As of today you can see a lot more data on the power curve. Previously it only showed the all-time best powers, but now it can also show the best powers for any year, month or week.

If you’re not familiar with this graphic, it shows the highest average power achieved for all time periods. Therefore, it shows the highest average power sustained for five seconds, one minute, five minutes, twenty minutes, one hour and everything in between. It’s useful for seeing what one is capable of doing, and can indicate performance improvements when looked at over time.

On not holding data hostage

10 May, 2012 by David Johnstone

A good reason for continuing to use a system is because it works very well. A bad reason for continuing to use a system is because you have heaps of data stuck in it with no way to get it out. So, in the interest of openness, and in the general desire to make an exceptionally user friendly product, Cycling Analytics now allows users to download all the ride data that they have uploaded. Users can go to the profile settings page and download a big zip file containing all their rides in the format that they were uploaded in.

Introducing Cycling Analytics

7 May, 2012 by David Johnstone

With the emergence of bike computers that record everything and allow for later analysis, not to mention the rise in popularity of power meters, cyclists have never before had access to so much data. All this data needs to be analysed somehow if it’s going to be of any use. The short story is that I wasn’t completely satisfied with what currently exists, so I made my own. Here it is.

Cycling Analytics is a website where cyclists can upload ride data and analyse it. I could spend a few paragraphs describing the functionality of the website, but it’s easier to just look at it. Here’s a ride I went on recently. From there, you can go to my list of rides, and there’s a few handy analytical tools lying around — a power curve, showing the highest average power sustained for all time lengths, and a training load table, which gives some indication of how much cycling one is currently doing. There’s a few nice things you can’t see without having an account, like the ability to automatically upload rides to Strava when they’re uploaded here.

I’ve been using this site for a little while now, and now you can too. For the moment it is free to use, but as of the 22nd of July it will cost $80/year. This site has a particular focus on power data because that data is more insightful than any other. Therefore, having a power meter is highly recommended, but not necessary. This currently only supports FIT files (which Garmin devices create). Support for TCX and SRM files is coming, as well as any other file formats that there is a demand for. You can check to see if your files are compatible with this tool.

There are many more features planned, so don’t think that the site will stay just like it currently is. In the near future there is a lot of work to be done improving what currently exists to make it nicer and expose more data to make the analytical tools more powerful. And I have a few more ideas…
