Wouldn't be in as I don't have FM6 (completely lost interest after FM5 and PCars has completely pulled me away from T10).
However, it does strike me that that 5000 miles is very high. As a comparison, I think the best distance achieved in the le Mans 24 Hours is 3300 or so miles at an average speed of 140ish mph, so you're looking at a distance of about 50% more than the 24 Hours. To add to that, my average speed across FM4 was in the 80's mph, so you're probably looking at about 60 hours racing. Unless you're talking a very long series (say 30 weeks or so), I suspect you'll need to bring down that 5000 miles to, say 1000 max for the series.

We all learn from our mistakes. I am very well educated...
