There is no current league ran in Indy Region. Please look into the SRF iRacing series that is part of the SCCA iRacing competition.
For more information, please visit SCCA.com at this link
If enough were interested, I would be happy to look into creating a league for us. I had a blast the one season we did this. Please let me know!
