The cost is $100 per bike (not per rider). You will not need to sign up or pay in advance or RSVP anymore for these Fridays. You can simply just show up and pay your $100 at the track on that Friday to test. This will make things easier on the MIROCK racers traveling for the events.
Also there will be no more lunches on the Fridays before MIROCK events, so please be sure to bring your own.
