What about weekly weeknight crits? We have 4 of them in the Dallas Fort Worth area. Tues/Wed/Wed/Thurs. I think they are making money? You can race for as little as about $20 at the minimum + bikereg fee. Say 100 riders paying an average of $27 (many do 2 of the crits). That's $2700 gross. Payouts are small. Pay the officials. Pay for the venue. Riders have to buy or rent their own timing chip. No police needed.
