Race balancing

Since I won my first race ai have been put into leagues with players who can consistently outperform me by 10-20 timelines.

Before I won my first race, I was always at least in the top 5. But since the I can bearly hit the top 15-20. I end up in leagues with players who can finish almost double the amout of timelines that I can. This will be my 7th race in a row where I can’t even reach top 15.

I was wondering if anybody had this same issue.
