For those interested, the event can be done in one sitting.
Don’t have to go day by day for 5 days. I upgraded to all 3s just in case it was a day by day thing
So far after 2 days worth, there was only one event I had to redo a few times (stay under an average speed and come 6th.) combining the 2 was a bit of a challenge but fun. And there is no off track problem :)

Edit - 
Lol, I love their maths for some of the events, for eg, win by 220 meters with an average speed of 186 kph
You either don’t win with the average speed or exceed by a large amount ( my average was 213 kph)
And yea I know their goals are often “a minimum of” etc but not always stated and still not that close ( but fun)
