Your laps

How can I upload laps?
First, export the laptimes from your app. Have a look at your app's help section or the guides above if you are not sure how to do that. Save the exported files to your computer. An easy way is to email the files to yourself and then save them on your computer. If you have a lot of .CSV files, you can zip them up to easily upload them all at once. Now, go to the Serious-Racing upload page. Click ‘Browse’ or ‘Choose file’ and navigate to the location where you saved your .CSV files or zipped folder. Click ‘Upload’ and the progress of your files will be displayed in a table showing which ones are still to be processed. Once they are all processed you'll be able to start analysing and comparing your data.
Upload laps from a GoPro

If you have a GoPro camera with GPS you can upload the laps from your trackday videos to Serious-Racing. First, go to the Upload page. You will need to do this from a laptop or computer; it won't work on a mobile phone. Select the vehicle you used during the session and choose the .mp4 video file on your computer.

Once you select your GoPro video, you will see a popup to indicate the progress of extracting the GPS data in your video.

In most cases, Serious-Racing will already know your track and show you a list of options and configurations to choose from. If your track is in the list, you are all done after this step and your laps will be uploaded.

If the video was taken on a new track, you will be asked to put in the name of the track.

For any new tracks, we will also need to know the starting point. You do this by dragging the marker as close as possible to the starting point. For accurate lap times, it is important to do this as precise as possible. On the map below, you can see you can't really do it without zooming in.

Zoom in using the plus and minus buttons to move the marker as close as possible to the start line. If you are struggling with this, do it as good as you can while uploading your laps and send us an email afterwards so we can edit it if needed.

Next you will be asked whether the track is circular. This is the case for most tracks, the exception being hillclimbs for example, where the start line is not the same as the finish line. If your track is not circular, you will need to indicate the finish line in the same way as you just did the start. After that, you are done and your laps are ready to be uploaded.

Upload via email.

To upload laps via email, you need to use the same email address as the one you signed up with. Your email address is shown on your profile page. Full instructions and where to send your laps to can be found on Upload.

Please note that this is an experimental feature. Processing your laps may take a few hours, but you should get an email back when your laps have been processed, even if there were issues. Make sure to check your spam folder first, but contact us at if you are not getting any email back from Serious-Racing Uploads.

Edit session vehicle and time.

Go to one of your tracks and select one or more laps from a sessions where you want to change time or vehicle. Click 'Edit' at the top right.

You now see a dialog with current session time and vehicle. If you have selected laps from multiple sessions you can only change the vehicle. Make the changes you need and click 'Save'. All laps in the session will be automatically changed.

Add vehicle settings.

1. If you do trackdays and want to add settings to a lap or session, go to the track and select a lap of the session you want to add settings to. Click 'Edit' at the top right. In the dialog, click 'Edit settings'. You can now add notes and any settings you'd like to record. Settings are automatically applied to all laps in a session and will be pulled into the 'Analyse' tab when you are viewing or comparing laps. Settings are only visible to friends.

2. If you don't have any lap time data and you just want to record settings you are using for your car or bike, go to your profile, then click the vehicle you want to add the settings for. On the vehicle timeline, under the big photo, click 'Add an update'. In the update dialog, choose 'Settings'. You can now record notes and settings for your vehicle. These will be saved on your vehicle timeline, and they will only be visible to friends.

Add a Youtube video.

Please make sure your video is set to Public on Youtube. Go to one of your tracks and select a single lap you want to add video to. Click ‘Edit’ at the top right of the page. Tap the ‘Add a Youtube video’ link:

Add the link to your Youtube video in the first field. Fill in the exact time where your lap starts in the second field. You can specify minutes, seconds, and milliseconds for the most realistic replay.

You can find the link to your video on the Youtube site in the share area:

You can change the video link or start time by selecting the lap again and tapping ‘Edit’. And you can also remove the video completely if you change your mind:

Share a lap.

By default, only the fastest lap of each of your tracks can be viewed by people you are friends with. If you want to show a lap to a wider circle of people, go to your list of laps and look out for the share icon:

Tap it to open the share dialog, where you can copy and paste the link to your lap, or share it directly to Facebook, Twitter, or Google+.

Press ‘Done’ or the close button when you are finished. The share icon will show up red now the lap is shared. If you want to stop sharing the lap, press ‘Stop sharing this lap’ and it won't be available anymore.

You can also share a lap from the lap view by tapping the share icon next to your name. Please note that you can only share one lap at a time, not a comparison.

Analyse your performance

Stay safe.
Always ride within your limits, and obeying all the rules and instructions of the track organisers. And have fun! Remember to read our terms of use to find out more about using Serious-Racing safely.
On the graph view, how do I zoom in and out?
To zoom in an area, click and drag. To zoom back out, double-click anywhere on the graph.
How do I compare with friends?
Go to the page of the track you want to see. You need to be friends with someone who has data for the same track. Select the one single lap that you want to compare, then click the button ‘Compare’. This will take you to a list of friends who were on the same track. Select up to 3 friends and click ‘Compare with friends’.
I want to compare a rainy lap.

By default, when you compare with friends, you only get their fastest lap. There is a workaround if you want to compare with another lap, for example laps with rainy conditions. You can read more about it on the blog.

First, your friend has to share their rainy lap, and you go view the share. Now, click Log in at the top right of the page, or in the menu on mobile. If you have laps on the same track, you will now go to a page where you can select one of your own laps to compare with the lap your friend shared.

I am missing some laps.
We automatically archive any laps that are 10% shorter or longer than the median length of laps on that track. This means in laps and out laps won't be included
How come sometimes on the map view I seem to go off track?
GPS is only accurate to about 10 metres or so currently (this will improve as the technology improves), and we can only be as accurate as the data that your GPS device records.
Why is my sector data missing?
This is most likely because your GPS data is not accurate enough. To calculate sector performance, we find the point on your GPS trace that is nearest to the sector location. If your GPS trace doesn't come near enough to the sector location, we can't show sector performance for that lap. If you are looking at sectors other than the first on the map and one or more laps have no sector data available, the dots of the laps with no sector data will be hidden. To see all dots again, tap on sector 1 to return to the start of the lap.
How do I get faster?
Serious-Racing is a tool for analysing and comparing lap timing data online. It can't make you faster on its own, but it can be a tool to help you figure out how to get faster. For example, when you compare your performance with a friend's, you might be faster on the straights, while your friend is faster in the corners. Your friend might brake a lot later than you before a corner and speed up earlier. Or if you view a single lap of yourself and check the analyse section, you will see a sector by sector analysis of where your performance is stronger and weaker, so that you know what to work on next time you are on track.

Buy laps

What laps are available to buy?
Right now we have laps available on a few tracks in the UK. You can see them all on Sylvain Guintoli's profile page. Whenever you are comparing your own laps, if there are any laps available to buy, we will show them to you in the step where you select friends to compare with. You can also see laps you can buy on track info pages.
What happens if I buy a lap?
After you've paid for the lap or bundle of laps and have clicked 'Return to merchant' you are back on the lap page and will now see a list of the laps you bought. Click on a lap to view it. If you have already uploaded your own lap time data of the same track to Serious-Racing, you will also see a step where you can select one of your laps to compare with.
Where can I find laps I've bought?
  1. Go to your profile. Laps you bought will appear at the bottom of the page. They are visible only to you.
  2. Go to the track info page of the track you bought laps of. Any laps you bought will be listed on the left hand side of the page.
How can I compare with laps I've bought?

It works the same as comparing with friends:

  1. Go to the track of the laps you bought.
  2. You should see all your laps listed under 'Your laps'.
  3. Select one of your laps you'd like to compare with.
  4. Click 'Compare'.
  5. Any laps you bought on the same track will appear at the top of the list, above your friends' laps.

About Serious-Racing

Why are you doing this?
We are trackday enthusiasts like you! We wanted a service like this ourselves; to keep a history of our recorded data and compare it with our buddies on the track. Although there are a lot of laptimer apps and hardware on the market, we couldn't find a place to share and learn from our friends. So we went ahead and built it ourselves.
We want to thank our beta testers, and all those who've given us feedback on the site and helped us improve it, particularly the Trackday Riders community. Icons come from the amazing Fontello project, from the sets Font Awesome, Entypo, Typicons, Iconic, Modern Pictograms, Meteocons and Elusive.

Didn't find the answer to your question here? Email us and we'll get back to you as soon as we can.
