I just ran the LeMans 10-lapper in Endurance Champions.  This is probably my new fame race, as it definitely adds a little excitement to the race.  I forgot to take a screenshot, but the fame payout was the same as the 10-lapper in Endurance Kings.  This one though is a rolling start, and you're put way back as the 22nd place bot can't be seen when you start.  

I had a couple of spin outs from trying to push the corners too hard trying to catch the bots.  In the end I finished 5000m ahead of the 2nd place bot, and lapped 5 cars.  And at least every lap you are trying to pass a bot, instead of the the 10-lapper in Endurance Kings where you are in first by the first couple of turns and you don't see any bots for the first 4 laps and end up lapping the entire field.    

Can't wait to get friends in this race.
