Lap Times Explained

Each column represents a vehicle driven on different racing lines. For example, the first row of the first column is the time for the Miata driven on its own line. The second row represents the Miata driven on the Porsche's racing line, and so on. It is expected that when a vehicle is driven on its own line (large font) the lap time will be the quickest. Otherwise, Al has not done his job very well.

Line Miata GT3 RS Moto F1 beta

The Racing Line at Anglesey - Coastal Circuit

The Anglesey Coastal Circuit is a popular configuration for track day riders due to the replacement of the Tom Pryce straight with the Corkscrew, which results in a track that is even shorter, with very little time spent not in a corner. The Corkscrew itself is a challenging section with camber and elevation changes. For the guide to the rest of the track, see the main article for Anglesey International.

Set up for the corkscrew begins with the exit from Turn 8. Four wheeled vehicles will typically exit 8 wider, and also come back to the far right before entering 11. Motorcycles approach Turn 9 from near mid-track. The line for all vehicles exiting Turn 10 is similar, with the Motorcycle staying slightly toward the inside.

As a final note, compare the Motorcycle line at this track to the one for Anglesey International, you will notice two different approaches to Turn 6. In the Coastal Circuit, the Motorcycle stays out very wide in the braking zone, then sweeps in and hits a late apex. At Anglesey International, the optimized line for the same vehicle stays more to the inside and enters the corner early, taking a tight line around the kerbing.

What explains this difference? Well, as you may suspect, there can be more than one line that results in an equivalent time through a section of track, or even an entire lap. In this case, if you examine the videos, you\'ll see that the Motorcycle is done braking and is back on the gas well before hitting the apex of Turn 6 in the Coastal Circuit. Conversely, for the International Circuit, the bike trail brakes all the way through the corner, and in fact is not on the gas until just after the apex. That would suggest that the first line is suitable for qualification or trackday lapping. Because the braking is later and the line is more to the inside in the latter case, it would seem to make that line more suitable for racing, where protecting the inside from passing opportunities is a higher priority.

I hope this example provides a little insight into the tradeoffs and possible options when taking a corner.

Miata Laps

Founder's Notes

In the lap comparison at the beginning of this video you can see how taking a wider exit from Turn 10 allows the top driver to gain several tenths on the bottom driver. Other than the narrow line through 10, the laps are very good.

BRSC Porsche Championship

Founder's Notes

This is a good video for learning the track, but not necessarily the the lines, which are very wide everywhere.

RGB Lap Record 2008

Founder's Notes

Sorry for the crap audio. Pretty good Miata racing in this video. Most drivers stick the right-hand side coming out of Turn 10, and this particular driver stays too far left coming out of 6.

RGB Lap Record 2008

Founder's Notes

Now this is a nice lap! The line is very close to the GT3 RS optimized one, but this driver doesn't take a double apex at Turn 2. Notice how s/he drives toward 7 from 6 without turning back past the middle of the track. The only mistake I saw was not carrying enough speed through Turn 10 and staying too far to the right before entering 11.

TTXGP Lap Record - Jenny Tinmouth (Electric Motorcycle)

Founder's Notes

Jenny shows us how to set a lap record on an electric motorcyce! Cool stuff. Although, I wasn't sure what type of vehicle to classify this under, seeing as the lap is 3 seconds slower than the Al's predicted time for the Miata!

GSXR-1000 Trackday

Founder's Notes

Thanks for the high quality vid HARRISAKI. There's a pretty fun battle in this video at around 6 minutes. This rider generally stays too wide on corner entries - the rider s/he's chasing has the opposite approach, sticking the inside a lot of the time.

Supersport Chase

Founder's Notes

Nice riding without having to battle through much traffic.
