MRF staff works hard to engage races and sometimes it will take a while to even convince the race directors to approve a discount. (Time is money and they invest a lot of time to gain exclusive discounts)
Race directors pull reports based off of code usage and at some races that is used for determining which clubs or groups they should continue to provide a discount for rather than others. (If you love saving money than please use the groups code so that businesses will continue to offer it to us)
If there is a race you would like a promo code for, please contact firstname.lastname@example.org with name of race, date and country the event is held at..
