Feature update: practice and qualifying lap downloads

You can now download a CSV containing every lap from practice and qualifying at any time, from the moment the session begins.

Feature update: practice and qualifying lap downloads

For a long time, you've been able to download a CSV of all the laps from a race. For example:

Lap Data - 2024 Cook Out 400 @ Richmond Raceway - Lap Raptor
Advanced analytics and loop data for all NASCAR series

And in the last few months, I've added session results, as here:

Busch Pole Qualifying - Final Round Results - 2024 Cup Series Cook Out 400 @ Richmond Raceway - Lap Raptor
Advanced analytics and loop data for all NASCAR series

Those are both only available post-race.

Now, we have live lap tracking of non-race sessions available from the moment the session starts. From a race preview page, you can download a CSV of all laps run in that session at any time:

Cook Out 400 Preview - Next Cup Series Race - Lap Raptor
Advanced analytics and loop data for all NASCAR series

You'll get something that looks like this:

series race_id run_id run_name flag_state_id leader_lap_number driver_id driver_name vehicle_elapsed_time status laps_completed last_lap_time last_lap_speed

After the race, when the preview has moved on to the next race, you can also download the laps from the session page on the race results page, like the Busch Pole Qualifying one above.

Thanks to Racing In The Draft for the suggestion. If you have anything you'd like see added to Lap Raptor, or anything you think can be done with lap-by-lap data since 2020, send me a DM on Twitter.


I find the current state of live race views lacking. I'm working on Lap Raptor Live, which will let you follow along with the race. Check out what I'm calling the alpha version below.
