Since the 2019 calendar year these changes have been made:
New Series:  W Series.
New Name:  Blancpain GT series renamed to GT World Challenge.
Series Cancelled:  ARX Americas Rallycross.

The Coronavirus has caused significant impact on the 2020 race calendar. I am trying to keep up and changes are in the comments and in a separate blog post, which will be updated over time.

Why Use These Calendars?

June 2015 IWTM Calendar with 21st selected.
June 2015 IWTM Calendar with the 14th selected. (click for large)
Agenda for 21st June 2015
Agenda for 13th June 2015 and the following few days (click for large)

I’ve been updating these since the 2011 racing season. Many decisions have been taken with experience, such as to make the usability the best it can be and to reduce the admin overhead. I will always listen to feedback but that doesn’t always mean I’ll implement it!

One series = One calendar
Pick championships that interest you without getting lots of dates for things you don’t care about.

In Google Calendar you can colour-code each championship, e.g. you could make all the endurance series green, single-seater series red, or rally series brown (for dirt..!).

Races Only
Races are why we are all here. Races are most important. Practice sessions clutter the feed meaning you can’t find the races. Clarity is better.
When you know the race day you can go to the series website to look up other session times. Use these calendars as a tool to remind you which weekend a race happens.

Dates, Not Times
Sorry, it is a big job for me to track race start times! These are announced much later than race dates, sometimes only days before a race. I cover 30+ series, I just can’t monitor them on a weekly basis. There is also the issue of timezone conversion…

No TV Times
I don’t know where you live! The internet is global. It is up to you to find out what TV, radio and online streaming coverage is available where you are.

Event Titles
Event titles are as consistent as possible:

A short series name, the round number, the event title.

F1 [R1] Australian Grand Prix
IndyCar [R5]
Indianapolis 500
WEC [R3] 24 Heures du Mans

I sometimes have to remove sponsor names for brevity, especially for NASCAR, some of those race names are incredible, so
NASCAR Monster Energy Cup Series [R22] Helluva Good Sour Cream Dips At The Glen
NASCAR Cup [R22] Watkins Glen

This is because I’m aware a lot of people, including me, use these on their mobile phone screensavers and you actually want to be able to read it!

Different series number their races in different ways. e.g. one series of 30 races may choose to have 30 individual round numbers (BTCC), another series of 20 races may choose to have 10 rounds and call them ’round 1 race 1′, ’round 1 race 2′, or ’round 1 feature race’ and ’round 1 sprint race’ (FIA F2). I try to mirror the way the championship does it but I’ve probably got this wrong somewhere, so just use this as a guide and consult the championship itself for the correct numbers.

Many series have two or three races per weekend. I merge multiple races in a day into a single entry, but if there are different races over 2 days they get one entry per day. A single race over 2 days, like Le Mans, will have one entry lasting 24 hours.

All rallies are listed as single events lasting 3 or 4 days.

Example entries:
Apr 3:  BTCC -R1,R2,R3- Brands Hatch

May 7:  DTM – R1 – Hockenheim
May 8:  DTM – R2 – Hockenheim

‘Misc’ Calendar
Catch-all. It includes such things as the Dakar Rally, Goodwood Festival of Speed, Isle of Man TT, Nurburgring 24 Hours, Bathurst 12 Hours and anything else that pops into my head.

‘Other Sport’ Calendar
I made this for my own benefit for the 2012 Olympics & Paralympics. I like to know that I’m not going to miss the Tour de France or the FA Cup Final or the Six Nations! Or that racing isn’t going to clash with it. It is heavily biased toward sports I watch and isn’t updated very often.

  1. Jason: Yes bikes are next – after my last comment I remembered WSBK starts very soon, so I’ll do all the bike series in the next 3 or 4 days. Come back Sunday night, though if you add them now, they might appear as I go.

    Cindy: I hadn’t even thought of MXGP! I had a look and I’d no idea the history goes back to the 1950s! That definitely merits inclusion. It also starts this month so I’ll get on it once the Superbikes and MotoGP are done.
    It’s also a nice transition into another category so I can go directly into WRX etc. the week after.


  2. Done:
    World Superbike;
    British Superbike;
    GP3 Series;

    Not all series will have a blog update – for example I’ve done GP3 but I’m not going to do a post about it. I may do one for BSB in a day or so.

  3. Hi, I have been using your calendars for a couple of years now and find it very helpful to plan when to watch races I like. I cannot find a calendar for the V8 Supercars for 2018. Have you created one yet? Cheers, Ed


  4. Sorry but I do get frustrated. I can only do things when time allows, and I have said multiple times that other life events caused me to start late this year. The series left to be done don’t even start for another 4 or 6 or 8 weeks! Just be patient, please.
    OK, this is the plan:
    PWC; Blancpain GT + Blancpain Asia; GT Open; British GT; ADAC GT; VLN;
    I’m working to a 3-day routine, so I input a calendar one day, the next day I write the blog post, the next I have downtime. I am not going to change this schedule to be faster.


  5. Just came across this and grabbed the MotoGP calendar, it’s exactly what I was looking for, because as you say, it’s all about the races 🙂 Thanks for taking the time to put this together.

  6. Hi Pat,
    I was sorry to read the comment that annoyed you – for what it’s worth it annoyed me too! Is there any scope to help you? I’d be happy to put some calendars together in CSV format so you can check and then import them straight into the relevant Google Calendar. If you think that would help then drop me an email.
    Thanks as always for all your efforts – you are an absolute star!
    Cheers, Yohan

  7. Apologies Bob. Thanks Dave and Yohan. 🙂

    To be honest it wasn’t that specific comment that annoyed me. I’ve had several comments and Twitter and Facebook messages, asking the same questions, at what is quite a busy and stressful time for me elsewhere.

    Everything done last year will be done this year plus some new things. By necessity, things starting in March and April will be done last. I’m sorry if that’s your favourite series but that’s the way it has to be.

    I’m also trying to stick to groups. When I did motocross, it made sense to keep to the off-road theme with rallycross. The next big thing to start is Supercars so for me it makes sense to check off the rest of the Touring Car group straight away, even though DTM starts in April. That leaves one last group and that’s ‘Other Sportscar’ which really means all the different GT3 series.

    The answer is the same as it always is: any calendar will be done before the first round of the championship.

    Okay yes they are much later than I would like (my personal deadline is the Rolex 24 Hours of Daytona weekend), but really, they are not late. Every calendar has appeared before the first round of that championship. It is mid-February now. People are asking for things that are over a month away, I’ve been tied up doing stuff starting the next week!

    I could change the process to do calendar dates first, blog posts after, but I have thought about this and I do need to spread out the posts. It’ll be overwhelming having them all go up at once. This is why I average about 3 per week.

    One last thing. I work in accounting. I deal with numbers and spreadsheets all the time. That means I need mental downtime some evenings. That means I can’t be working on this every weeknight. I’m sorry if some of you don’t like that, but that’s the way it is.

    Thank you to those of you who continue to support this project.


  8. Hi guys – Supercars are done, by popular demand!

    I am not sure I got the race formats right – in researching 2018 I discovered I got a lot of race formats wrong for 2017 where they changed after ’16 and I missed it. I would really appreciate it if someone knowledgeable about the series could please just check and let me know?

    It has been (another!) fairly busy work week so I hope the blog post makes sense. My focus right now is getting calendars right and just banging up a blog when I get the chance.

    I think VASC is the last series with 30 dates, all the rest are much much shorter, so I really hope I can get through them faster. Also the busy spell at work is over so I’ll have more mental space (the first two weeks of every month are really full-on, then I get some breathing space). DTM, BTCC and WTCR will all be done by next Friday.


  9. Great work, thanks. Is the BSB iCal working fine? It just hangs when I click on it; wasn’t sure if it’s just my iPhone that is the issue …..


  10. Cancel my last! I use Google Chrome on my iPhone and normally have no problems. I decided to try your BSB iCal link via Safari and it worked!! Once again, many thanks.


  11. Hi Martin – yes I had a problem with the BSB calendar last week, it gave me a permissions error. I refreshed the links on this page and on the BSB blog post just in case and that seems to have cleared it.

    If anyone is stuck, please delete and resubscribe and let me know if still having problems.



  12. World TCR (World Touring Car Cup) added using the calendar for the WTCC (World Touring Car Championship).

    TCR Europe added (no blog post) using the existing calendar of the now-defunct TCR International. If you subscribe to TCR International from now on you’ll see dates for the Europe series.


  13. Hi everyone,
    I’m working on the GT series now, that’s the final group.

    To be done:
    Blancpain Series
    Blancpain Asia (new)
    GT Open
    British GT
    VLN (new)

    Nearly there!


  14. THANK YOU so much for taking the time to do this, Really, really appreciate the effort. This has saved me and the Mrs a lot of time as we are both big fans of motor racing. Thanks

  16. Hi everyone. All calendars done!

    There are blog posts scheduled over the next few days, however all of the dates for those series are now in place.

  17. Exactly what I was looking for – thank you for putting time into this, official calendars are often way too noisy / broadcast oriented.

  18. I really want to take you for one or two glasses of beer for this. you’re awesome man. anyway, if you can include F4 series and Formula Renault that would be cool too. but cheers dude!


  19. Hi,
    I will be updating 2019 calendars in autumn & winter. I have no intention of wasting a good summer sitting here typing in dates. 🙂

    One thing I will promise is that I will start earlier this time. Last time I had to wait until December because of other things going on in life, this time I hope to start in early October. By then most TBAs in various series will be firmed up.

    (The one exception I may make is Formula E because of the early season start.)

    Cheers and please do keep following.
