A very tough race. I qualified for it in January and just finished last week. I had to put it down for a while. When I finally did win, each win was by at most three or four seconds on every race. White knuckles the whole way.

Get out early and don't let them pass you.
Go to "practice" and try out each course so that you know what gear you should be in, etc.; you don't want any surprises.
Stick with it! In the beginning I would get a few seconds behind and re-start the race -- DON'T. (Unless you are absolutely getting whipped). The competition seems to "settle down" in the middle of the race. If you are in last place by three seconds in lap 10 you could still EASILY win it. Just hang in there.
Again, go to the practice section and try out different tunes, etc.; The first time I won I had on anti-skid and was using (gah!) automatic because I wasn't shifting fast enough.
You will get different opinions on this, but I would (and did) use traction control, which I don't use normally. Sometimes I consider it a "cheat," but when a car has this much horsepower with so little weight and my DS3 throttle is either "off" or "on," I consider it fair.
Have fun! If you aren't, put it down for a while. Who knows, you may be one of the people posting here who says it was easy the first time out. Good luck, let us know how you did!👍
(edit) P.S. -- I used Jorday's tune from the link which I recommended (above). Great tune.
